Abstract

When a free falling ping-pong ball collides on a horizontal surface, it loses kinetic energy. The ratio between the height reached by the ball after the collision and the initial height is called restitution coefficient. A method to measure it by using a home-made cathetometer was proposed during the Olimpiadi di Fisica 2018. In this paper we show how to measure it also by using the PhyPhox app and Arduino board.
