We'll look at what happens during the golf swing, during impact, and during the ball's flight. Nowhere near everything, of course. We will focus on some issues which are important for clubfitting, especially: Where does the power for the swing come from? The answer will probably surprise you. What happens during impact, and how does it turn clubhead design and path into launch conditions? This is the bottom line, turning a swing into a golf shot. What determines the ball's flight? How do the launch conditions (ball speed, launch angle, and spin) translate into distance and direction. Once we have these fundamentals under our belts, let's look critically at a few myths that have perpetuated themselves in golf lore. What powers the swing? Many golfers, especially in the United States, grew up with sports in which a ball is thrown o...
