    Abstract

    The oblique impact between a golf ball and a rigid steel target was studied using a high-speed video camera. Video images recorded before and after the impact were used to determine the inbound velocity vi, rebound velocity vr, inbound angle θi, rebound angle θr, and the coefficient of restitution e. The results showed that θr and e decreased as vi increased. The maximum compression ratio ηc, contact time tc, average angular velocity ω̄, and tangential velocity v̄, along the target were determined from images obtained during the impact. The images demonstrated that ηc increased with vi while tc decreased. In addition, ω̄ and v̄t increased almost linearly as vi increased. A rigid body model was used to estimate the final angular velocity ω* and tangential velocity vt* at the end of the impact; these results were then compared with experimental data.
