Me and a few friends of mine were discussing if mass plays a role in the speed of a free falling body. They argued that equal bodies (same volume, same geometry) with different weights (mass) would fall at different velocities. I defended that mass has no part on the matter, but only air resistance. Meaning that if two equal balls (same radius), one made of iron another made of cork, were dropped from an airplane, both would reach the ground at the same time. I am aware that in vacuum as long as both bodies are dropped from the same height they will hit the ground at the same time, regardless the shape or weight. Since there's no air resistance. Was I right or wrong? Is air resistance affected by mass or just by the contact surface (geometry)?
