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 ms-1 to 20.2 ms-1. It w

We investigate estimation methods of aerodynamic coefficients for a ball in sports by using characteristic quantities of its trajectory. One method is based on the quantities representing the whole shape of trajectory while the other utilizes local q

The coefficient of restitution (COR) of a bouncing table tennis ball was measured at varying ball temperatures with a Motion Detector. It was found that there is a negative linear relationship between the COR and the temperature of the table tennis b
