Coefficient of Restitution

Coefficient of Restitution (COR)
The amount of energy put into a golf ball as compared to the amount of energy at (after) impact. The COR is the relation between rebound velocity and initial velocity. Putty would have a COR of 0.

Coefficient of Restitution (COR) - A USGA adopted test of measurement of the rate of rebound of a golf ball from a standard collision surface. The current USGA standard is 0.82.

Coefficient of Restitution: The relationship of the clubhead speed at impact to the velocity of the ball after it has been struck. This measure is affected by the clubhead and ball material.

The Coefficient of Restitution (COR) is a scientific ratio which measures the efficiency of the impact between the ball and the clubhead.

COR: Coefficient of restitution. Measures the amount of bounce effect if the face caves in at impact.
Core: The center of the golf ball.

R: Coefficient Of Restitution — The measurement of the “spring' of a golf ball off of the club face at impact.

- 152 mph, John Daly - 143 mph, Tiger Woods - 137 mph, average tour player - 115 mph, average amateur - 80 mph (Note: these are approximations and averages, and readings can vary significantly between measuring devices) coefficient of restitution ...

A proprietary combination of metals designed by the Liquidmetal™ Golf Company. The special alloy is designed to feel soft, yet have a high coefficient of restitution.

Instead, these balls are measured by a coefficiency rating, which is the ratio of initial speed to return speed after the ball has struck a metal plate. This procedure measures the coefficient of restitution.

Face flexibility at the point of contact, commonly known as 'spring-like' or 'trampoline' effect or COR (coefficient of restitution), plays a significant role in a driver's ability to provide maximum distance.
