Rocking Roly Poly Toy

This Demonstration simulates the rocking motion of a Roly Poly toy.
This hollow toy is bottom weighted with its center of mass beneath its center of rotation. When pushed from its upright equilibrium position and released, it oscillates vertically. Because of frictional damping, it eventually moves back to its equilibrium position.
