What Is COR Rule? How Does It Work?

lowpriceaugolf -
In golf, there are many golf rules and terminologies which you need to understand and use. Some rules are very important in golf playing. For example, each golf player is requested to take only 14 cheap golf clubs. Everyone should comply with this rule. And there are also some other rules used in golf skill. Today, I would like to talk about COR. It is rule and a way to calculate the ball speed and club speed. Once you swing the Titleist 917 D2 Driver Australia out, there is a speed. Then you can know your COR.

Actually, COR is a measure of the efficiency of the transfer of momentum between two colliding bodies. To better understand the concept of COR imagine that a ball is flung at a rigid brick wall at 100 mph and it bounces back at 75mph the COR is 75/100 = 0.75 .Exit Velocity divided by Approach velocity = COR

It is not possible to get a COR of 1.00 as this would mean that there was no energy loss during impact. There is a limit to COR which is governed by the Laws of Physics. We all intuitively know that a ball will not bounce higher than from where it was dropped, no matter how resilient the ball or how "springy" the surface. No matter how technology advances or new materials develop, the resilience of impact is limited.

From a practical point of view knowing that even sound is a form of energy loss the estimated high on COR is about 0.930. COR OF A Scotty Cameron Select Newport Putter australia AND BALL COLLISION. Taking into account the weight of the ball and the club head and the speeds of these two colliding bodies, before and after impact one can calculate the COR.

If the face of the Titleist 917F2 Fairway Wood Australia deforms and recovers during impact, like a trampoline, this takes up some of the deformation that would have otherwise been in the ball, the COR would increase as there are fewer losses in the deformation and recovery of the club face than in the ball. COR RULE In 1998 The USGA set the COR limit for woods at 0.822 with a test tolerance of .008 effectively taking the limit up to 0.830. This is about 0.06 above no SLE and equivalent to about 10-15 yards in distance based on the resulting increased ball velocity and change in launch conditions.

So, if your COR value is bigger, then your efficiency of the transfer of momentum between two colliding bodies is bigger. But COR rule would be different in translation in different area or country. Many golf players seldom us this rule. If you are playing golf, you can calculate your own COR to check about your swing speed.
