Looking for an answer to this. If I have a cylindrical tumbler that is rotating on its axis at a fast speed, on an inclined plane and I fill this tumbler with objects will the rate of speed that the tumbler is spinning affect the speed at which the objects fall out (due to gravity and mass)? Will a slower speed cause the objects to fall out faster because there is less centripetal force holding the objects to the walls? Or would a faster speed allow the objects to fall out quicker because there is increased mass due to their acceleration and speed or some other force acting upon them?
