Our objective is to study the deformation of the trampoline when something is thrown from a determined height, as well as the movement of the articulations of our body while we are jumping on the trampoline.
The behaviour of the ball is based on the gravity and the loss of energy. When the ball goes down the gravity is the only force that has an influence above it. When the ball hits the trampoline, the last one undergoes a deformation and then gets back to the initial position. In that moment the ball is propelled by the trampoline. If it was an elastic collision, it would obey the law of conservation of energy and in every bounce the ball would reach the same height. But as it’s a partially inelastic collision, in every bounce an amount of energy is lost and the height that reaches the ball is getting cushioned.Coming soon
