What has physics got to do with fast bowling?
I have found that there are three concepts that govern fast bowling. Good technique allows you to successfully perform all three of the key concepts in the correct order. The good news is that good technique is very easy to understand. First let’s look at the three concepts: • The generation of ‘kinetic energy’ in the run-up. In a human body, kinetic energy (think of it as movement energy) arises from the contraction or shortening of muscles. These muscles are fuelled by chemical energy stored in the body. • The stretching of elastic tissue prior to delivery. Like an elastic band, the muscles store ‘elastic’ potential energy. This stored energy allows the muscles to return explosively to their original length. Correct technique will allow us to use these stretched tissues to speed up our bowling • The efficient transfer of energy to the ball. An efficient bowler uses the kinetic energy generated from his run-up and transfers it to the ball by using correct technique. This is ultimately
