Paddle Angle and Ball Spin in Table Tennis
by Broca, B., Chen, A., Kraivisitkul, N., Poprom, P.
Abstract
The relationship between the impact angle of a table tennis ball with respect to the paddle and angular velocity of the ball leaving the paddle was investigated. A table tennis ball was dropped onto a paddle oriented at impact angles ranging from 10° to 80°. It was found that the sine of the impact angle is proportional to the angular velocity of the ball as it leaves the paddle for all impact angles tested.
