The oblique impact of golf balls with a rigid steel target was studied using a high-speed video camera. The video images recorded before and after impact were used to determine the incident and rebound velocities and angles of the balls. The rebound velocity was found to decrease to about 80% of the incident velocity. The rebound angle also showed that it decreases with the incident velocity. The video images during the impact were employed to evaluate the contact time, compression ratio, tangential and angular velocities of the balls. The result showed that the contact time decreases with the incident velocity, while the opposite relation was obtained for the compression ratio. It is found that the tangential and angular velocities increase linearly with the incident velocity. A rigid ball model was also employed to analyze the tangential and angular velocities of the ball during the oblique impact with the target
