概要

One of the performance of the racket is to control a ball, and which relates to the motion and the rotation of the ball after impact. But there is few research which considers the rotation of the ball. The purpose of this research is to analyze the motion of the ball which impacts the face of strings aslant by taking high speed photograph. By using the mirror and the racket whose flame is cut, the motion of the impact is shown three dimensionaly. And this research notices how the ball with spin influences the motion of the impact and rotation after impact. The higher the negative rotational speed becomes, the lower the rotational speed after impact becomes. The rotational speed of the ball after impact is high when the deformation of the strings is smal and the velocity of the ball relling on the strings is high.
