Experiment Ms-02

Rotational Energy

Description: A large yo-yo is hung by two strings.  The yo-yo is wound up in the string.  When the string unwinds from the axle and converts the gravitational potential energy to kinetic energy of rotational and a very small amount of translational energy.  When the yo-yo reaches the bottom, the string rewinds and allows the kinetic energy to be restored as potential energy.
