Golf Physics
As anyone who has played a round of golf will attest to, the sport is based around many fundamental principals of physics. These basic laws are involved with every aspect of the game from how a player swings the club to how the ball moves through the air on its way toward the pin. It is the challenge that physics presents to the golfer that has allowed the game, and equipment used, to develop so drastically over the past one hundred years. The great sport of golf was introduced to me by my dad over ten years ago. I spend hours weekly fighting the physics this sport, and it is this challenge that attracts me to the game. When deciding what to research for my YOYO project, only golf was what came to mind. The physics of this game are so vitally important to becoming a great golfer; only those that can defy the laws soundly are able to achieve greatness.Before delving into an elaborate discussion on the physics of golf, it is necessary to know just how far the little dimpled ball has come. The first golf balls used were called featheries. They were made with a horsehide cover packed with wet goose feathers. When the balls dried they became extremely hard. The major flaw with the featheries was that they could not be used when t
Tait, performed the first experiments done with the aerodynamics of a golf ball in 1887. 5 This led to another major revolution in the design of the golf ball. He found that the ratio of the speed with which the ball leaves the floor to that with which the ball approaches the floor to be practically a constant over a large range of speeds. 1 The elastic properties of the ball come into place at this point because it is those properties that allow the ball to be compressed and then spring away from the face of the club at a high velocity. The stroke is actually three separate events; the swing of the club, the impact of the club head with the ball, and the flight of the ball toward the target. Torque: Torque is the term used to describe twist in a quantitative manner. Not only was this ball cheap to manufacture, but also it could be hit farther than any other ball previously used. Momentum is conserved: Since the club head is at the end of a somewhat flexible shaft, we may assume that the club head in its horizontal motion at the bottom of the swing acts as a free body. Thus, momentum is not conserved because a force acts and there is no displacement because the ha!nd remains still. As demonstrated by any golfer who can hit a ball in a straight line, the aerodynamic forces at work on a golf ball are what make the flight of the ball so unique. Its motion is the result of a lack of centripetal force rather than the result of an outwardly directed force being applied to the ball. Before investigating the details of the golf stroke, it is important for us to consider the general concepts of motion that control the swing of the golf club. It is the principles of these two men that will be used during this dissertation- oops, I mean discussion- of the physics of golf. The effective loft of any club is given as LE = L + a(i) - B(i) - Y. The energy is derived from the muscles in the golfers body.
