Impact Velocity and Coefficient of Restitution of a Table Tennis Ball
by Krin Muangsiri
Abstract
The impact of a table tennis ball upon a paddle was recorded using a high-speed camera. The effect of the ball’s initial impact velocity on its coefficient of restitution was determined for impact velocities ranging from 1.4 m/s to 20.2 m/s. It was found that the coefficient of restitution decreased linearly with increasing impact velocity.
