This simulation compares the motion of a ball experiencing uniform circular motion to two different simple harmonic motions, one vertical and one horizontal. The point of the simulation is to show that the horizontal motion of the ball exactly matches that of the ball attached to the horizontal spring, and that the vertical motion of the ball exactly matches that of the ball attached to the vertical spring.

The graph also shows that the position versus time graphs of these motions are sinusoidal.
