![]() In this study, the determination of the coefficient of restitution was carried out in two ways: by comparing the height of the ball’s bounce and the time intervals for the n and n+1 bounce. The rounder a thing is, the higher the level of accuracy will be. This error is highly dependent on the shape of the object. Furthermore, the average error value of the overall measurement is 0.97%. The results show that the value of the coefficient of restitution for each marble was 0.93, 0.92, and 0.92, while the average error was 0.65%, 0.85%, and 1.43%, respectively. In this study, the determination of the height of the bounce from the “bouncing ball” was measured using the Phyphox application, which was analyzed based on the sound of the bouncing ball and the time interval of the reflection. Theoretically, the value of the coefficient of restitution is obtained based on the square root of the final height of the object’s reflection divided by its initial height. The produced sound came from a reflection between marble and the floor. The experiment used a Phyphox-based smartphone. This study aims to determine the restitution coefficient based on the reflected sound from the “bouncing ball” experiment.
