Paintball in space...wow.  No Flatlines/Apex's needed!  Who's game?  I'll see you on the dark side of the moon.

You misstated that a little bit.  Gravity causes the same accelleration for all objects, regardless of mass.  On the moon, a bowling ball and a feather will fall at the same rate.

But greater mass does allow an object to better overcome air resistance, which is why heavier objects often fall faster.

In a vaccuum, all objects fall at a constant rate, which is proportional to the gravity in the area. However with air resistance factored in, an object can only fall at its terminal velocity, or slower.

sooooo.....

Since the BB has a similar mass to a paintball, but is much smaller, that means it is more dense, therefor it should hit the ground before the paintball.

Really as soon as each on leaves the barrel it begins falling. The real question you should ask is, if you fire a paintball out of a gun with no mods, and drop a paintball from the same height at the same instant, which will hit the ground first?

The answer is that they will hit the ground at the same time. Even though the fired paintball has lateral movement, it is still pulled down by gravity at the same rate as the dropped paintball.

Ok, I got my rootbeer float now. I just have to copy this whole article to the clipboard in case the forum has a seizure.

Actually, it wouldnt work. Paintballs spin coming out of the barrel regardless of how fast. Without proper gravitational force, the spin would make the ball do a loop.

actually, in space there is no air to act upon the spin, so it would still go straight.

He speaks the truth. The spin has to have some type of friction in order to have any affect on the ball.
