Of the two, the ball loses by far the most energy when a shot is hit because it can squash as much as 30% of its diameter against the face of the driver. This is because the face flexes inward and the ball is compressed against the face. In the collision of the clubface and the ball, there is always some energy lost. Actually, higher COR faces work like this. When you think of spring face, it is easy to think that the ball causes the clubface to flex inward, and upon flexing back out the ball is propelled as in the manner of a trampoline sling shotting a gymnast up. The COR rule also became known as the “spring face rule.” This was a little unfortunate because in fact, a higher COR clubface does not really act like a spring. For example, when the USGA put a COR limit of 0.830 on driver faces, that meant no driver would be deemed to be conforming to the rules if more than 83% of the energy in the collision of the driver head with a golf ball were transferred from the head to the ball. It can be expressed in a number between 0 and 1. COR is actually a measurement of the energy transfer in a collision of two objects. The terms 'coefficient of restitution' and 'COR' came into the mainstream golf lexicon as ultra-thin-faced drivers began to. The lower compression works synergistically with a high COR face. These are a low compression ball that will enhance performance and durability on shaved drivers. Acting before ever doing any testing, the USGA blamed the pros’ distance increase on the use of the relatively new (at that time) titanium drivers and enacted a rule that placed a limit on the COR of all driver faces. COR made its way into the golf industry’s vernacular back in 1998 when the United States Golf Association got freaked out at the distance the pros were hitting the ball.

Experienced golfers know the COR is a number which represents how “hot” the face of their clubhead(s) is made – or rather how much distance they can get out of the shot for their swing speed. One that has been a buzz-acronym in the golf equipment industry since 1998 is COR – short for Coefficient of Restitution.
Companies, organizations and industries love to use acronyms because these abbreviations of longer terms can so easily roll off the tongue.
