Impact tests were carried out with two different kinds of golf balls, a two piece ball and a wound ball. Dynamic contact time between the ball and target was experimentally determined by using FSR (Force Sensing Resister) sensor. To examine the applicability of FSR sensor to the impact measurement, the experimental results werecompared with those obtained from a load cell and high-speed pictures taken by a Cranz-Schardin type camera. The results showed that FSR sensor is applicable to the appropriate measurement of the dynamic contact time, especially at impact velocities lower than 25m/s.
