Coefficient of Restitution by Video Analysis,at this is a simple method to obtain the restitution coefficient of several pair of materials, measuring just the initial height of the ball made of one substance and the maximum height after the collision with the floor formed of another material.

Bi-Dimensional Collision,) and one glass ball (target), both differing in mass and diameter. The setup consists in abandoning a projectile ball on the top of a curved launching platform suspended and attached on a support bench. At the end of the platform seats the target ball a bit misaligned. Upon reaching the base of the

The free software Tracker is an efficient tool for obtaining measurements of position and time of the center of mass in both phases of the movement. The experimental results allow to measure the kinetic and rolling friction coefficients.
