A proper golf swing obviously has an enormous impact on your game of golf. The golf swing has physics written all over it and is a great example of angular motion. The twisting swing produces torque on the club. This torque force changes the angular velocity of the club, causing rotation. Most club heads weigh about the same, so the key to being able to hit the long ball lies in the club head velocity. The faster your club head is going at the bottom of your swing, the greater the amount of kinetic energy that will be transferred from club head to the ball.
