Coefficient of restitution of a golf ball
WebThe coefficient of restitution (COR, also denoted by e), is the ratio of the final to initial relative speed between two objects after they collide.It normally ranges from 0 to 1 where … WebJan 22, 2024 · Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity.
