The match between theory and experiment is shown below. Note, the mathematics for a rolling ball is not simple, the potential energy is converted into translational kinetic energy Kt and rotational kinetic energy Kr. For a solid sphere, Kt/Kr =5/2 (see[http://cnx.org/content/m14391/latest/ Work and energy in rolling motion])
The match between theory and experiment is shown below. Note, the mathematics for a rolling ball is not simple, the potential energy is converted into translational kinetic energy, Kt and rotational kinetic energy, Kr.
Mgh = Kt + Kr = 1/2 Mv^2 + 1/2 Iw^2
For a solid sphere, Kt/Kr =5/2 (see[http://cnx.org/content/m14391/latest/ Work and energy in rolling motion])
