I believe i have found a realism failure.

There are two weights (red and blue) exactly the same size dropped from the same height.
One is twice as heavy as the other (blue)
Notice that the blue weight falls much faster than the red

That's supposed to happen because of air resistance. Turn off air friction, and they will fall at the same rate.

That's not a bug. It's supposed to happen due to the relationship between the air's density compared to the ball's

The redone is 1.00 KG and the blue one 2.00 KG.

Since the mass is double, Its Kinetic energy is double (mass*gravity*height) Another fact is the law of conservation of energy, according to which the energy in a body will remain constant, though its form may change. What is happening here is that through free fall the potential energy is changing to Kinetic one. To stay consistent with the law of conservation of energy, the blue ball will have double the velocity.
