The Bouncing Ball


Drag the mass with the mouse to its new starting position.
Once in motion, the mass can be 'caught' by clicking and holding it with the mouse.
You can also change the angle of the floor by dragging in the horizontal direction on the bar under the "dip" in the floor.

This applet shows the mass bouncing from the walls of the box. The mass moves under the force of gravity, and all collisions are elastic. The angle at which the mass hits the surface is equal to the angle at which it leaves the surface.
