Drive is the most common ball type of table tennis1, but there is a high-bouncing general drive and a low-bouncing drive. In order to clarify the mechanism of the latter drive, we used a table tennis machine and a digital camera (960 frames per second), and examined changes in the angle, rotation number, and velocity speed of the ball before and after the ground contact. As a result, it was found that a ball with a large number of revolutions before the ground contact does not bounce greatly, part of the rotational energy is converted into velocity energy, and it becomes a low-bouncing and fast drive.
