Oblique impact tests of a golf ball and a transparent PMMA plate target were carried out to study the dynamic contact behavior. Using a high-speed video camera, the contact behavior was photographed as a function of time. The result showed that the maximum contact area increased linearly with the incident velocity of a ball, while the contact time decreased with the velocity. The video images were also analyzed to study the tangential and rotational velocities during the contact, and compared with the results determined from the steel target and the rigid ball model.
