2012). Essentially‚ it measures the rebound of a ball after a collision with another object‚ like a golf club striking a stationary golf ball. A perfectly elastic ball will have a COR of 1‚ and a perfectly plastic ball will have a COR of 0. In golf‚ the coefficient of restitution comes into play when the club head impacts the ball‚ and has a direct effect on how far the ball will travel after impact. Once the club head strikes the ball‚ the ball is deformed and flattened by the impact and the transfer
