Coefficient of restitution of a tennis ball
WebApr 16, 2024 · In 1998, the USGA implemented COR (coefficient of restitution) limitations on golf clubs. According to the rules, COR could not exceed 0.822 with a tolerance of 0.08, meaning any driver... WebHere is the equation for the coefficient of restitution. e = √ hb / hd. Coefficient of restitution= the square root of the height of the bounce divided by the height of the drop. For this project we measured the COR of a Titlelist 4 golf ball. We dropped the ball from a height of 1.24m five times to get a consistent height of the bounce.
