When a golf ball is being hit by a club face, there are three separate and distinct phases of the collision. First, the clubhead makes contact with the ball and COMPRESSES and DEFORMS the ball. This compression is stored energy in the ball. Second, when the ball cannot be compressed anymore, the clubhead starts pushing the compressed ball along the path of the swing with clubs from heygolfer online shop. Third, when the clubhead is slowing down from the impact with the ball, the compression on the ball is released and the ball literally JUMPS off the clubface. The energy of the JUMP comes from the materials of the golf ball returning to their original shape. How much the initial energy input into the ball on first impact is returned when it jumps off the clubface is called the coefficient of restitution. If the CR is 100%, then 100% of the energy input into the ball is returned when it jumps off the clubface. In the real world, this is not possible due to friction and heat. High quality golf balls hit with a very clean impact can reach a CR of appropriately 80%. So, lets now walk through the clubface hitting the ball with clubs from heygolfer.com with some speed. And I will simplify the numbers to make the mathematics easy. Just assume for a moment that the clubface is traveling at 100 km/hour and hits a golf ball that is standing still. The clubface then comes into contact with the ball and starts to deform it. The energy from this deformation is stored in the golf ball. Therefore, with a clubface swinging at 100 km/hour, we have been able to hit a golf ball with a speed of 130 km/hour by combining the energy stored in the ball with the energy of the swinging the club from heygolfer.com. This is why a golf ball has more speed than the moving clubhead! All of the values in this second case are exactly the same as above EXCEPT the speed at which the clubhead is moving when the ball jumps off the clubface is not 50 km/hour, but 80 km/hour. The golfer has achieved this NOT by swinging faster, but rather by resisting the tendency of the clubface to slowdown during impact with the ball. The golfer has continued to either hit or swing all the way through and past impact. Simply improving on getting a very clean sweet spot hit on the clubface with help you to get closer to the 80% value, and get more distance without swinging faster. |
