## Radius of gyration of a steel ball

Apr 23, 2021

The radius of gyration is an account of the location of the mass inside a given bowling ball and relates whether the ball mass is concentrated toward the center of the ball (low RG), toward the coverstock of the ball (high RG), or between the two points (medium RG)
