Abstract
The normal impact between a golf ball and a rigid steel target was studied using a high-speed video camera. Video images recorded before and after impact were used to determine the inbound and rebound ball velocities. The images during impact were also employed to analyze the deformation of the ball. Displacement at the center of the ball was measured during impact to determine the instantaneous ball velocity and acceleration. Reaction force was evaluated by the product between the mass and acceleration of the ball. It was found that the force increased linearly with the inbound velocity.
