Quite frankly, there are a number of movements that are related to physics that help us achieve a proper impact position. The first one is lag pressure, which is the natural lagging of the club as you move with weight shift and turn into the downswing. The second is centrifugal force, which helps you release the club as it attempts to fly away from you during the downswing, away from the center of the circle. Both of these actions happen naturally, as long as your hands and wrists stay soft throughout the motion. Any undue influence on the club can make you hit the ground too soon. As long as you shift weight and pivot into the downswing with your hands and wrists soft, you will get your ball first and then the turf impact!
