Anthony stated that the shotgun pellets slow as they arrive back to earth, after being shot in the air. Well, all objects, when sent away from earth at a velocity return via gravity to the same point with the same velocity, because gravity is constant.
I laymans...Gravity pulls on things. If you shoot away from the earth gravity immediately begins slowing the pelllets with it's pull. When those pellets reach their peak they begin falling back towards earth and gravity then increases their velocity equivalent to the exact amount it decreased their speed on the way up....

Well then you forgot a little thing called "terminal velocity" which dictates the maximum velocity a falling body can attain in a free fall due to gravity. In other words, the pellets falling back to earth can only get to a certain speed due to gravity which may or may not be equal to their inital upward velocity.

For example, if you shot a wad of paper in the air with high explosives at a rate of 500 miles-per-hour, no matter how high that paper wad went, it would not reach 500 miles-per-hour upon its decent. Not even close. The same goes for bullets, birdshot, human bodies, etc.

THAT's physics, shitdick.

You forgot air resistance. Air resistance will slow down the pellets do to friction.

That would be true in a vacuum.

Also, earth is curved so the curvature would affect it's landing. So would its spin.

Terminal Velocity for a small object like a rain drop is 76 m/s.

Yeah...Um...we're talking about bullets...Shot...Not paper..OBVIOUSLY things have air resistance, however the air resistance of a lead sphere is much less than that of paper. Shot is going to still be moving very fast and be very dangerous when it gets back to earth. They have had a lot of calls from the south lately and i don't want some moron getting killed trying to catch pellets.

32 is acceleration due to gravity, not velocity. ACCELERATION is measured in ft per second per second (ft/s^2).

TreeFort is correct. Although the pellets won't be going the 800fps that they left the muzzle of the weapon, I promise tha they'll be going fast enough to fuck you up more than just someone throwing a handfull of gravel at you.

And yes, I did send in an instant feedback, but he didn't read it.

32 feet per second / per second is actually the acceleration of a falling body due to gravity, the only thing that influences terminal velocity is the actual shape of the object.

The pellets falling back to earth from a shot straight in the air would not be enough to do serious damage, they dont have the mass or velocity to pierce the skin, let alone go through the skull or muscle tissue.

Mythbusters did the whole penny off the empire state building thing, and although the penny would create more air resistance than the pellets, the penny has more mass. I believe the a penny and a pellet falling at their respective terminal velocities would do about the same damage, which is little to no damage, maybe a bump or 2 on the head.

Anthony actually made another minor mistake but it's so nitpicky that you can't hold it against Professor Anthony. He said that if you shot shotgun pellets up on the moon that they would only hit with 1/6 the force on the way back down. Since there is no atmosphere on the moon, only the moon's gravity would slow the pellets down, not wind resistance. So first of all the pellets would go farther up than they would if the moon had an atmosphere similar to that of the earth. Then on the way back down, since there is no atmosphere, there is no wind resistance to make the pellets hit terminal velocity. Therefore the pellets would keep accelerating downward until they hit the groung or the person who took the shots.

Also, just to show where the moon's gravity being 1/6th as strong as the earth's gravity comes from, the force due to gravity is given by F = Gm1m2 / r^2 where G is a constant equal to 6.67x10^-11 Nm^2/kg^2, m1 is the mass of one object, m2 is the mass of the other object, and r is the distance between the two masses. The mass of earth is 5.98x10^24 kg and its mean radius is 6.37x10^6 m. The mass of the moon is 7.35x10^22 kg and the mean radius is 1.74x10^6 m.

Let's say you want to find the force due to gravity on a 10 kg mass on both earth and the moon. On earth the force would be equal to
F = (6.67x10^-11 Nm^2/kg^2 x 5.98x10^24 m x 10 kg) / (6.37x10^6 m)^2
F = 98.2 Newtons

On the moon it would be
F = (6.67x10^-11 Nm^2/kg^2 x 7.35x10^22 kg x 10 kg) / (1.74x10^6m)^2
F = 16.2 Newtons

Divide the force on earth by the force on the moon
98.2 N / 16.2N = 6
The force of gravity is 6 times greater on the earth than is is on the moon. The force is a result of both the masses of the two objects and the distance between the two object. Sorry, Jimmy, it has nothing to do with the rotation.

Just for the sake of it, the sun which is thousands of times more massive than the earth and whose gravity is thousands of times that of the earth only spins once about its axis every month, whereas the earth obviously does every day.

I used to work at a gun club. There was a course in the woods, and then basic skeet and trap. while in the woods I was peppered on more than one occasion. It stings, but it does not break skin. pellets have very little weight, and have a low terminal velocity. Also they would have been using steel pellets and not lead, so they may have been lighter depending on the size of the shot

I would bet that shot gun pellets would achieve escape velocity if shot straight off the moon...

Don West
02-15-2006, 06:35 PM
And here's another interesting tidbit of information. Since the earth is rotating, due to the centripetal acceleration, the earth slightle bulges at the equator (this same force would make you weigh less if the earth had the same shape but was not rotating, just as Anthony mentioned on the program) and it is kind of squished down at the north and south poles so that the earth is kind of like an oval. Therefore, since you would be closer to the earth's center of mass at the north or south pole than you would at the equator, you would weigh more at one of the pole than you would at the equator. The rotation of the earth would slightly make you weigh less as well but its effect is negligible.

You neglected air resistance, which is reasonable at times, but definitely not in this situation. When you are shooting something out of a gun its already well past its terminal velocity, so it instantly starts slowing down. Just because it went out of the gun very fast, doesn't mean its terminal velocity is that fast, or that it will come back down at the same speed.

Nothing on Earth can fall faster than 32 feet per second (without another influence).

I know a thing or two about a thing or two...

STFU you idiot.

Mythbusters did the whole penny off the empire state building thing, and although the penny would create more air resistance than the pellets, the penny has more mass. I believe the a penny and a pellet falling at their respective terminal velocities would do about the same damage, which is little to no damage, maybe a bump or 2 on the head.

The penny started to spin on mythbusters though, and caused more air resistance. Regardless, you're right. The bullet would not harm you on the way back down.

Don West

Escape speed is given by
v = ((2GM) / R)^1/2
Where G is the gravitational constant again, M is the mass of the planet, and R is the Radius of the planet. So on the moon it would be
v = ((2 x 6.67x10^-11 x 7.35x10^22 kg) / 1.74x10^6m)^1/2
v = 2373.8 m/s
Which is equal to 7788 feet/second or 5310 mph. When a bullet comes out of a gun's barrell it's travelling about 900 feet/second and it may be lower when your talking about a shotgun. So no, the pellets would not exceed the escape velocity of the moon.

Never ceases to amaze me how fucking smart (or damn good at fast research) some Wackbaggers are. I totally forgot about terminal velocity, too, when I started reading this. However, on the moon, wouldn't the pellets theoretically eventually stop accelerating because the gravitational field wasn't strong enough to give them additional velocity(assuming they hit 0 velocity far enough from the surface)? Or am I a fucko that's misremembering his High School physics class?



Edit: Actually, I think the theory of relativity says you cannot ACCELERATE to the speed of light. You can come within a hairs width of C, but not actually reach it. Technical difference. Bending space and/or time changes that, though. The thesis also states time likely stops if you achieve the speed of light.

If its initial velocity was 2300 m/s or more, then yes that would be correct. Any less and it would still be sufficiently under the influence of the moons gravity to pull it back down.

ChrisC_EIT
02-15-2006, 07:41 PM
Well... Nothing you shoot into the sky will come down with the same velocity. Never. The air resistance going up and down guarantees that. While it’s likely that any “shotgun blast” (including bird and other shot) will reach terminal velocity by the time that it reaches earth again, it’s unlikely that the shot would necessarily produce grand injury in the victim. I do not know exactly what the shot size or load was, but I’ve been hit with shot before and while it “hurt” it didn’t break skin and mostly was just annoying.

Let’s not forget that the Professor has some experience with shotguns. It’s not just him talking about his ass about what he saw three years ago on Discovery.

Point was that Cheney’s friend wasn’t “peppered” but was SHOT.

But if you were able to creae a stable worm hole, you could arrive at another place in the universe, possibly light years away, in a fraction of the time traveling directly to that point. And then theres the warp drive theory. Both theories go around the dilemma of mass inceasing as you approach the speed of light.

If you drop a cannon ball off a building will it hit the ground at a slower speed than a cannon ball fired from a cannon up to the hight of the building, arching, and returning to the ground?

Your theory would have the fired cannon ball hitting the ground with at the same velocity it left the cannon at! RE-fucking-diculous.

Wouldn't the cannon ball fired on top of the building hit the ground at a higher velocity b/c it has more time on its way down to pick up speed? I think a falling object on earth accelerates at 32 fps ^2^2... I think

Anyone care to comment on Ant's theory of the airfoil effect generated by the hog bulge of male lugers? According to fluid dynamics, the air will increase in velocity as it passes over resulting in a localized low pressure zone = lift. This will reduce friction on the runners which will increase speed. However, I believe it would negatively impact turn-in ability and control. Also, depending on the size of the hog, the air stream may detach sufficiently high enough to smooth flow over the helmet (the one covering his face) reducing drag. I'll need to listen to the replay again but I think Ant said it would act like a reversed airfoil on a race car that generates negative lift or "downforce". Or is this another thread...

Okkk if the ball peaks at the building height then yes they will hit the ground at the same speed. But a 'wicked aerodynamic' projectile (discounting all the wind crap) if fired straight up at 800m/s will come back down and hit the barrel at 800m/s because the + and - effects of gravity cancel out, decreasing velocity on the way up at the same rate as it increases velocity on the way down...
Now i don't know if you heard the show today WBL :icon_wink But Professor said "Peppered is when you fire off your round. the blast goes up and the pellets fall down and hit you. There is no velocity left from the actual shotgun blast from the gun powder. The only velocity is now gravity...." (MyFi)
The point of my ned nitpicker post was that ALL of the velocity is due to the shotgun blast because the pellets had a velocity that was + (up) from the barrel that had gravity acting on it - (down) and then they hit a peak where then the - gravity of up is now a + force accelerating the pellets back to the barrel. If a player throws a baseball straight up at 90mph it will fall back down and be going 90mph when it reaches the height he let it go. Gravity is constant and the principle applies to the shotgun pellets as well, (but the wind restistance steals a lot of the velocity..)
WBL ROCKS :)

I'll need to listen to the replay again but I think Ant said it would act like a reversed airfoil on a race car that generates negative lift or "downforce". Or is this another thread...

But if you were able to creae a stable worm hole, you could arrive at another place in the universe, possibly light years away, in a fraction of the time traveling directly to that point. And then theres the warp drive theory. Both theories go around the dilemma of mass inceasing as you approach the speed of light.

now we just need to figure out how to take 2 points in the space/time fabric, pinch them together and then travel through it. WOW we got alot of fucken work ahead of us!

Good thread, though. I have nothing to add that hasn't been mentioned though, aside from also agreeing that a 28 gauge spraying bb's up, is not going to fuck you up on the way down as bad as TFR said in the opening post. That's just not the way it works. Not even in the least. Someone likened it to getting a handful of gravel thrown on you, that's about accurate. It'd require gravel larger than said bb's however.

Any idea how heavy, in measurement those bb's were, anyone?

I would just like to point out that my post intially had nothing to do with injury. My prob was with the assertion that the shotgun pellets had no remaining velocity from the initial firing upon their return to their origin. That's all...Now granted as usuall this is all over the place now, but I love it. I just wanted to point out that because the pellets got in the air from the gun all of their velocity is from the gun. Gravity is constant.

If a player throws a baseball straight up at 90mph it will fall back down and be going 90mph when it reaches the height he let it go.

No it won't.

I don't know if it was your example regarding shooting the same shot on the moon - but yes, disregarding any effects from the motion of the moon itself (it's spin or wobble) or it's shape (curvature), shot fired from a shotgun would arrive back on the moon at the same speed.

REGARDLESS of the speed at which the objects leave the cannons, once they reach apogee and start their decent, the most basic of gravitational laws takes over.
They are now just two objects of equal mass being dropped from the same height. The speed at which they left the cannons now has nothing to do with the speed that they will hit the ground even though the object leaving the cannon on the left would have been fired at a much higher velocity.

Your post is very correct, and would be aprropriate if there were 2 groups of hunters, 2 on different hills overlooking a valley w/ 2 different types of guns....but your example is not the same as my original post. At the point the cannoball returns to the exact altitude of the cannon it was fired from it is going the same speed as it was when it left the cannon...The cannon on the left must have a higher muzzle velocity to elevate the cannon ball against gravity than the cannon on the right. The extra fall distance once the balls fall below their origin is all gravity. I was never talking about that...I want to go so far as to apply the ole 'apples and organges' here... My whole point in all of this, nothing else, was that the velocity of the pellets from the gun is all due to the gun. I promise this is the last time i write this velocity up = velocity down...gravity cancels out. That is all.

Your text is poorly written, as it is completely disregarding air resistance. What is the title and author and publisher if you don't mind my asking?

The baseball thrown vertically at 90 mph will not reach EARTH 1 at 90 mph when it returns. It meets air resistance on the way up so it never reaches the height at which it needs to fall to once again achieve it's initial velocity.

Interestingly, in the case of the baseball, it's terminal velocity is just a shade over 90mph so the air resistance on the way down doesn't really come into play.

The air resistance still works against the ball when it starts to fall though. It starts accelerating from its maximum height reached at 9.8m/s^2, but air resistance slows down that acceleration as the ball picks up speed on its descent.

WTF r u talking about? weaker load? the force on both c-balls is the same, so they should both travel the same distance, as long as there both at the same angle..im guessing 90 degrees... if the cannon on the hill is 200 feet higher then that ball should peak, or it's apogee should be 200 feet higher that the other ball launched from the lower hill.

Ok, I get your point but I can not accept your saying that if I fire a shotgun into the air and stand underneath it I will be injured as if it was fired at me from point blank range. I know I would not be hit by every piece of shot but even one hitting me at the speed it had coming out of the barrel would kill me if it hit my head. It just wouldn't happen.
I know that. I am not denying that. I don't think it would do more than dent you...All I was saying when I started this 'Thread that is just exploding' is that you said on the....Anthony said on the air that there is none of the original velocity of the gun left. All of the velocity of the falling shot is from the gun, but it is not all there anymore. The majority of it is lost due to wind resistance, but NONE of it is lost due to gravity. On it's way up gravity has a -9.8m/s^2 effect, and on it's way down gravity has a +9.8m/s^2 effect on the shot. These 2 cancel each other out. Then air has a - effect on both the up and down and continually slows the object, but all of the remaining velocity is from the gun(only a lot less) and not gravity.

the object took a certain amount of force to get to its peak. This force is a + vertical force, with a -9.9m/s^2 force of gravity acting on it for the duration of its vertical travel. Then when it peaks and begins decending it has a +9.8m/s^2 force on it. That will act on it for a period of time = to the amount of time it takes to get back to it's origin. This is the same amount time it took it to get from the origin to the peak. Because you have the same force of gravity acting on it you end up with the same speed.

see, here is the problem with this logic.

the pellets in this case are at rest before the gun is fired. In the split second that they start moving, their accelleration is almost infinate in comparison. Even though the pellets have moved only a fraction of a centimeter, their accelleration is an enormous amount. Even by the time they have left the barrell of the gun they have slowed down tremendously compared to the initial blast. when they return to earth, they will not be accellerating at the same speed as they were at first.

I will try to exmplain this as simply as I can. When the "object" is being shot upward it is being propelled by in this case gunpowder. If I fire my SKS straight up the air the bullet is leaving the muzzle at about 2300 fps. It is going that fast because of the explosion forcing it out that fast. As the bullet reaches its apex it has used up all of that energy given to it by the gunpwder.

The bullets return trip to earth is courtesy of gravity alone and its terminal velocity (a couple of hundred mph) will NEVER come anywhere close to what it was when it left the gun with the help of the gunpowder.

Let me know if I can elaborate further.

Although i find all of the stories about firing bullets in the air fascinating, I will tell you again, please read carefully. I am not, nor have i ever, been talking about wind resistance (Ie term velocity). If an object is thrown/shot/flung/catapulted away from a mass...and read carefully...is in a HUGE vacuum(No air, and no air resistance) and that mass has the same exact mass as the earth, so it's gravitational pull is 9.8m/s^2 (not an equation, a constant) the object will return to it's origin at the exact same speed it left it's origin. The ONLY!!!! Force acting upon this object is gravity.

I am a pilot and I regularly have some fun at the shooting range and I have common sense.
I am being honest when i tell you I know you have not take a physics course b/c what you are saying is like someone telling you your plane is flying faster into the wind because the prop is going faster. where as a pilot you know that your speed is relative to the ground and you will actually be going slower into the wind...Please just agree...please...or my head will xplode! :action-sm

That link is still talking about ideal projectile motion without air resistance, which acts in the opposite direction of the movement upward and then downward.

Physics starts out with the ideal concepts(easy to grasp) and then adds non-ideal/real world applications(slightly harder to understand) later in the lessons.

See skydiving example which shows how the Force of air resistance affects you as you fall.

I will concede that in a vaccuum and with the bullet then having unlimited downward acceleration it is then possible for the bullet to pass the gun at the same speed it was fired. However, anthony's diagram didn't assume that we were in a vaccuum. When you start taking things like air out of the hypothetical situation it loses its relevance to the topic.

02-15-2006, 09:52 PM
TFR is right... ignoring all other factors, a projectile fired up will expend all of its kinetic energy to reach its peak, after that it will be accellerated downward at 32 fps/s (gravity on earth) landing with the exact same speed that it left with. If air resistance is factored in than the projectile will fall at terminal velicity, if it reached a height sufficient for it to acclerate to terminal velocity. and i did physics in college.

The force dues to air restistance is given by F = 1/2 CdAv^2 where C is the drag coefficient, d is the air density, A is the cross sectional area of the object and v is the velocity. At terminal velocity the force due to gravity is equal to the drag force so you set them equal (the simplified equation for the force due to gravity is F = mg).
1/2 CdAv^2 = mg
Solving this for v gives
v = (2mg / CdA)^1/2

The only problem is getting the coefficient of drag which is pretty much different for every object and is usually found experimentally


And whoever said something about something having gone faster than the speed of light earlier is wrong. It hasn't happened nor will it ever happen. You can get infinitely close to the speed of light (they've gotten subatomic particles to go over 99.99% of the speed of light) but never reach it. Impossibly long distances may be traversed eventually but it will not be due to going faster than the speed of light, it will be due to taking advantage of the curvature of spacetime.

Are you insane?
If you drop a cannon ball off a building will it hit the ground at a slower speed than a cannon ball fired from a cannon up to the hight of the building, arching, and returning to the ground?

Your theory would have the fired cannon ball hitting the ground with at the same velocity it left the cannon at! RE-fucking-diculous.

Its going to depend on the height youre dropping it from. However, if you wanna get silly with this, the same amount of force applied to the fired cannonball to get it to the height of the building was ALSO applied to the dropped cannonball....by hauling it the roof of said building to start with. Again, on assumption, if the fired cannonball came to a dead stop at, say, 100m above the ground, and began its fall, it would hit the ground with the exact same force as a cannonball DROPPED from the same height.

So, yes, they hit the ground at the same velocity, regardless of how damn fast the fired one was going when it left the cannon.
I guess its key to remember that since the ball comes to a DEAD STOP at the apex (vertically anyway) then its speed on impact is totally determined by the height of said apex.

Basically, WBL is right. Took me all that fucking typing just to agree with him. I stink.

Yes, the objects hit the "ground" at the same speed, but they also travel at the same speed at points A and B.

TreeFortRichard would have you believe that at point A they travel at the initial velocity of the low velocity cannon, and at point B they are up to the initial velocity of the high velocity cannon.

One of the undeniable axioms in physics with regard to terminal velocity is that the more dense and compact an object is the greater it's speed, of course the drag coefficient has to be considered as well. However, an even less considered byproduct is the Wile E. Coyote factor wich would allow you to say, stand on the previously discussed cannonball as it fell to the earth and at the last moment before impact- step off to the side without sustaining injury.

Okay, your original post:
Anthony stated that the shotgun pellets slow as they arrive back to earth, after being shot in the air. Well, all objects, when sent away from earth at a velocity return via gravity to the same point with the same velocity, because gravity is constant.
So you're saying the pellet's speed of motion (velocity) is the same falling from the sky as it is being shot from the barrel?

Gun powder creates the ascent, gravity creates the decent. Gun powder is stronger than gravity, if it wasn't the fuckin things wouldn't go up in the first place. Therefore, they move faster after being propelled by gunpowder than if just gravity pulled it down.

Bravo WoodenPlank! Best damn explanation in the whole thread. TFR, you're wrong - sorry.

If two identical things "fall" from the same height - regardless of how they got there - their potential energy prior to the fall is the same.

One may have gotten there by being shot out of a cannon and ultimately losing upward velocity due to gravity until it's motionless for a split second at a particular height.

The other could be carried to the exact same height up a ladder.

If both "things" have the same physical characteristics (ie - identical cannon balls), then they will fall at the same rate - REGARDLESS OF HOW THEY GOT TO THE POINT WHERE THEY STARTED DESCENDING!

The initial velocity out of the gun, cannon, whatever has nothing to do with it.

IF gravity were the only factor, TFR's (theoretical) argument that an object fired into the air reaches it's initial velocity upon return is absolutely correct. But here in the real world, such factors as air resistance and terminal velocity actually exist.

And I'm not sure the Wile E. Coyote theory is accurate either, as I rarely see the Coyote escape injury. (But I have seen him stand in mid air, at least until he looked down and realized there was nothing supporting him).

I am going to have to disagree with the whole thread, and please feel free to flame away at me if i am wrong because i didnt get a chance to catch todays show, but this thread is assuming that the bullet was shot at a 90 degree angle, meaning straight into the air. i believe that if it is 85-95 degrees, the bullet will go up, stop, and come back down at terminal velocity (given it has time to reach it, or maybe it is automatically there, i dont know/care). however, if it is fired at any other angle, the bullet will not actually stop in mid-air and come down, it will arch, and by doing so, it will not lose all of the force from the gun firing it

i guess they did use the right term for how the guy was shot!peppering - Collaborative International Dictionary of English v.0.48 :

Pepper \Pep"per\, v. t. [imp. & p. p. Peppered; p. pr. & vb.
n. Peppering.]
1. To sprinkle or season with pepper.
[1913 Webster]

2. Figuratively: To shower shot or other missiles, or blows,
upon; to pelt; to fill with shot, or cover with bruises or
wounds; as, to pepper him with buckshot. "I have peppered
two of them." "I am peppered, I warrant, for this world."
--Shak.
[1913 Webster]

Peppering \Pep"per*ing\, a.
Hot; pungent; peppery. --Swift.
[1913 Webster]
and from dictionary.com
tr.v. pep·pered, pep·per·ing, pep·pers

1. To season or sprinkle with pepper.
2. To sprinkle liberally; dot.
3. To shower with or as if with small missiles. See Synonyms at barrage2.
4. To make (a speech, for example) lively and vivid with wit or invective.

and just to be thorough here is the definition of missile
mis·sile Audio pronunciation of "missile" ( P ) Pronunciation Key (msl, -l)
n.

1. An object or weapon that is fired, thrown, dropped, or otherwise projected at a target; a projectile.
2. A guided missile.

well apparantly not all of us paid any attention in school.

A projectile is in 2 vectors, and the y vector (height) stops when deceleration due to gravity = velocity (differential equations). Then it returns to earth with an acceleration of 9.81ft/sec*sec. UNTIL it reaches terminal velocity which DOES NOT equal exit velocity of the gun.

Stupid people. :fight6: Keep claiming you know physics...:icon_roll :icon_roll


Oh yeah, SPINNING OF THE PLANET HAS NO EFFECT ON GRAVITY fuckheads. Its all mass atTraction. The equation to determine gravity is M1M2/D. Mass of object 1 times mass of object 2 divided by distance.

DUMBASSES.

This is WACKBAG my friend...I think half of us are just monkeys hitting the right keys every once in a while...:icon_bigg

There are *some* of us who are engineers who apply years of physics to design the fun things you use on a daily basis. There are also *some* of us who have hunted with birdshot and know that birdshot falling from the sky with the full force of gravity to propel it doesn't have the kinetic energy to break skin or do anything more than greatly annoy.

I was going to let this die, but you bumped it :) All i will say is that if you read my first post i was simply trying to explain that the falling pellets are falling at a rate determined by the force at which they were elevated by the shot, and I was not including wind resistance because that is a - force. The Velocity of the falling pellets was determined by the shotgun force they were fired with, and not gravity. I know that gravity is pulling them down, but what people forget is that it was always pulling down at the same rate and that rate is - on the way up (slowing it) and + on the way down (Speeding it back up) at the same rate.
...Gravity pulls on things. If you shoot away from the earth gravity immediately begins slowing the pelllets with it's pull. When those pellets reach their peak they begin falling back towards earth and gravity then increases their velocity equivalent to the exact amount it decreased their speed on the way up....
ChrisC if you read the first post you will get what i am saying.(please!!!)..I can't believe this thing made it to 9 friggin pages....

I have read everything you've written. Much to my dismay, I might add.

You aren't correct. You are very wrong. You are also confusing two things in further posts - wind resistance and air resistance. *Wind* can theoretically "help" in that if air is moving in the direction of travel, then it applies a net positive force. Yes, wind can be vertical. The presence of *air*, however, is ALWAYS a detriment to motion.

An object propelled away from earth, no matter what the propellant is, no matter what the initial velocity is, will not reach earth (or as we would prefer, the initial elevation) with the same velocity except for one case - a vacuum. Where there is air resistance (not wind - AIR), an object will never reach the height that is required for that item to fall to earth with the same velocity as it was propelled.

This is completely ignoring the issue of "terminal velocity." Terminal Velocity doesn't even need to be part of this issue. However, the fact that a shotgun would be fired into the air, propelling objects FAR FAR FAR beyond their terminal velocity should really tell you something about your hypothesis and the point that Mr. Cumia was making during the show in regards to the notion of the term "peppering" and how it's being used to make it sound like VP Cheney didn't *shoot* Harry Whittington.

Frankly, your science stinks sir. Your reference to a textbook example was oversimplified because the writers wanted you to crawl before you ran. It's far easier to work on and understand F = ma without worrying about the problems of friction. You've made about 37 references to gravity being constant. Yes it is. So is the presence of air here on earth. I sincerely hope you've noticed that air is all around us. There is also no reason to discuss topics like vectors, since we're only concerned with the vertical component anyway.

I suppose I shouldn't have bumped the thread this morning. I guess I just feel it necessary to protect my own sometimes. I honestly smell a Mythbusters on this although frankly, it's probably a little dangerous in that it would get kids to start shooting each other, I'm sure.

Wrong. Re-read your link.

The rotation of the earth about its axis has NOTHING to do with gravity. :icon_roll
