Friction Physics Lab

Game description:

"The plank controls friction. When friction is on, the yellow objects will slow down when they collide with each other. When friction is off, the yellow objects will continue moving at the same speed when they collide with each other. The screen background controls gravity. When gravity is on, the yellow objects will fall down when they are not on the plank. When gravity is off, the yellow objects will float in the air."
