Temperature of the object will increase with friction as it falls. But I guess your genius mind must had already know that.

No moving of the goal posts.
Besides even a hot bowling ball will have air resistance.
but would it decrease the air resisitance? if you had a ten pound ball at 3,000 f and a same sized ball at absolute zero, would they fall at eh same rate? would the temp difference affect it enough for the lighter ball to fall faster?

oops...the absolute zero ball would weigh twenty pounds while being the same size as the ten pound ball....

Why do you claim that the propelled object will hit the ground first.

I will tell why the answer is "it depends" for the case of a vacuum if you do.

Now a question that will fry your brain.
Drop a 22 bullet and fire a 22 bullet on a level plane of equal height. Negate wind and air resistance effects.
Which one will hit the ground first?
Depends on the velocity and gr of the bullet a typical 40 gr 22 bullet will have a muzzle velocity somewhere around 1250 ft per second and will travel over a mile so the fired bullets gunna have a hell of a head start on the one you just drop

does gravity work differently on the bullet with more velocity? why?

in some places, yes. and for both objects...

absolutely nothing to do with my question, though...but then you probably DIDN'T know that...

Ooh, that could get nasty. If the ball is hot enough any air leaving it will pick up speed. And if the ball is cold enough air hitting it will leave the ball moving slower ( the temperature is directly related to the speed of the molecules in the air ). I could formulate a reason why either one would fall slower than a ball of the same temperature as the air. Hotter and colder and I am not so sure.

The difference would be minuscule.

you said it would be the same from the top of a house or as high as i can reach. you were incorrect.

Well its going a lot faster to begin with by the time they are travelling at the same speed again the fired bullet is way ahead so of course it will hit the ground first

Ok it is a depends, theoretically they will hit the ground at the same time. Meaning a bullet dropped that takes 1 second to hit the ground. And a bullet fired from the same height will hit the ground 1 second later 1250 feet from the other.

But...

Then we have the answer given by those who've achieved spiritual awareness as a result of regular reading of the Straight Dope. This may be summarized as follows: it depends. If the fired bullet travels only a short distance, then yes, both bullets hit the ground at the same time. However, if the fired bullet travels far enough, the earth, being round, curves away from it.(Remember Newton's first law of motion: moving objects tend to travel in a straight line.) Since the fired bullet has farther to fall, it takes longer to hit the earth, so the dropped bullet hits the ground first.

What's more, if the fired bullet travels fast enough (roughly five miles per second — a practical impossibility given atmospheric friction, but never mind), it goes into orbit around the earth and never hits the ground at all. Amazing, no? Try this one out in your next physics class and you'll kill the whole hour, guaranteed.

Myth busters did it and found slight variations. But surprisingly they will hit nearly the same time. Just one a long ways from the other.

Actually retard the higher temp would decrease air resistance and the force needed to push the air out of the way making the heated object less air resistant. And you act like you are smart. Go read some more books and come back in a year or two.

I said "But if you still think two objects of different weights fall at the same speed I will bet you what ever you want that a 20lb weight will reach the ground faster than a ostrich feather when dropped from a house top or even from as high as you can reach."

Being reach is a well respected term of standing and reaching plus you will never be higher than that.

as miniscule as the air resistance difference against a ten pound ball that is the same size as a twenty pound ball?

or more?

No vacuum the propelled will be pushed way ahead. As I said in a no vacuum space I am not sure. I would almost say no difference being there is no resistance at all but that is a guess.

Here's the video. The problem is their synchronization could be off , so I say it's within
+-that error. They hit same time.

why would gravity pull the speeding bullet down faster than the dropped bullet?
