The Physics of Golf
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 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 the conditions were wet because they would soften again.[5] Despite the flaw of the featheries, they remained the only ball used up until the middle of the 19th century when the revolutionary gutta-percha ball was invented. The new ball, sometimes referred to as a "guttie", was molded from the warmed, dried gum of the sapodilla tree.[5] These balls were cheap to manufacture and opened up the game of golf to a more diverse socio-economic group. This in turn made the game of golf very popular, which led to dramatic improvements in golf balls in the
However, drag is also produced, which threatens to pull the ball back toward the earth. Newton was the first to experiment with this property of collisions. [ ] The constant is called the coefficient of restitution. Momentum is conserved: Since the club head is at the end of a somewhat flexible shaft, one may, to a fair degree of approximation, assume that the club head in its horizontal motion at the bottom of the swing acts as a free body. This also applies to collisions that happen at an angle such as with the face of the golf club and the ball. drag which causes the ball to slow down and fly closer to the ground). This is important to understanding how the whip works. The other two illustrations show a three-dimensional (on the top) and a two-dimensional (on the bottom) view of some of the vectors involved with the flight of a golf ball. The moments of inertia in the two cases differ by a factor of 10. This generates the tremendous amount of spin necessary to keep the ball a loft for drives at or above 230 yards. This action gives the ball a rotation around its horizontal axis, which creates lift and drag. The energy is derived from the muscles in the golfers body. It is the principles of these two men that will be used during the discussion of the physics of golf. As the collision occurs the ball begins to slide toward the top of the face of the club.
