1R40.10 - Coefficient of Restitution
To demonstrate the different values of the Coefficient of Restitution for different balls made of a variety of materials.
Place the restitution board behind a steel plate that is the same height as the lowest mark on the board. Provide the professor with a minimum of 3 different types of balls with very different coefficients of restitution.
Hold the ball even with the top of the restitution board and release it. Observe the rebound height of the ball. The numbers indicated on the restitution board are percentages of the original height value. Compare the different ball's coefficient of restitution.
