Why Low Bounce Balls Exhibit High Rolling Resistance
Cross, Rod
Physics Education, v50 n6 p717-721 Nov 2015
A simple experiment is described to measure the coefficient of rolling friction for a low bounce ball rolling on a horizontal surface. As observed previously by others, the coefficient increased with rolling speed. The energy loss due to rolling friction can be explained in terms of the measured coefficient of restitution for the ball, meaning that low bounce balls have a higher coefficient of rolling friction than high bounce balls.
