Dynamic collision and object mass

[FredZX]

I’m starting to play with dynamic collision.
Maybe this is a trivial question, but why do objects with different masses (A = x, B = 9999x ) fall at the same speed ?

Generally, physics engines doesn’t calculate and apply air resistance.

[niclas_aberg_winkel]

Mathias is right, this isn’t a standard feature of physics engines. However you may be able to manipulate linear_damping and angular_damping to achieve something close to air resistance.

It’s been a long time since I studied physics, but isn’t mass irrelevant anyway? In a vacuum, a cannonball and a feather would hit the ground at the same time.
