A Cure for Hooks and Slices? Asymmetric Dimple Patterns and Golf Ball Flight

Science Fair Project Idea

Scientific Method

Have you ever wondered why golf balls have a pattern of dimples on their surface? The dimples are important for determining how air flows around the ball when it is in flight. The dimple pattern, combined with the spin imparted to the ball when hit by the club, greatly influence the ball's flight path. For example, backspin generates lift, prolonging flight. When the ball is not hit squarely with the club, varying degrees of sidespin are imparted to the ball. A clockwise sidespin (viewed from… Read more
