Golf Ball Flight Dynamics - Union College

Golf Ball Flight DynamicsBrett BurglundRyan Street5-13-20111 AbstractProjectile motion is a field of study that has many practical appli-cations. In this case the projection of a golf ball will be analyzed. Thegolf balls projection is effected by many different forces, here the spinand drag will be the main areas of concern. A system of differentialequations will be interpreted from aerodynamics and drag to aid inthe discussion. Specifically, the magnus effect and resistance due toaerodynamic drag are IntroductionGolf balls didn t all ways have dimples on them. The dimpled golf ballwas first introduce in 1905 by Wiliam Taylor, an engineer. He found thatdimpled balls were more aerodynamic , allowing golfers to have better controland further drives. The number of dimples on a typical golf ball ranges from250-450. Each manufacture has a different theory on the number of dimples,depth of dimple and in the pattern in which the dimples are placed.

plotted to show the e ects of angular acceleration and aerodynamic drag. One system is used to model a smooth ball while another is used model a dimpled ball. Throughout the models the initial velocity and angle of attack a ect the trajectories. Initial velocity is …
