Abstract
An evaluation method includes determining, by a computer processor, the times of occurrence of states of a golf ball during its contact with a collision surface, from the behavior of the golf ball based on its collision with the collision surface. A slide time or slide amount is calculated by the computer processor, based on the times of occurrence of the states. The slide time is a period from the start to the stop of a slide of the golf ball on the collision surface. The slide amount is the amount of the slide during the period. Information on the slide time or slide amount is output by the computer processor.
