1. And all because there is agreement on the matter of coefficient of restitution . 2. The featherie and the guttie ball had low to modest coefficients of restitution . 3. A coefficient of restitution is some number, 0 \ le e \ le 1. 4. A slightly more complicated strategy that offers more control would involve using the coefficient of restitution . 5. They measured whether the Coefficient of Restitution ( COR ) is in keeping with major-league rules. 6. So you really need to know the'coefficient of restitution 'of the various structures that are impacting and being impacted. 7. The origin is a hard surface, and a coefficient of restitution between it and the ball of e. 8. This depends on the coefficient of restitution , which is zero if the body in question is the OP's brother. 9. Just how well any given ball jumps off the club depends on what's known as its coefficient of restitution . 10. Lab technicians measure the coefficient of restitution , calculated by dividing the outgoing velocity of the ball by 58.4 miles per hour.
