Coefficient of restitution experiment
WebThe coefficient of restitution (COR, also denoted by e), is the ratio of the final to initial relative speed between two objects after they collide.It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision.A perfectly inelastic collision has a coefficient of 0, but a 0 value does not have to be perfectly inelastic. It is measured in the Leeb rebound … WebAn experiment was performed in which 15 drivers produced by a particular club maker were selected at random and their coefficients of restitution measured. In the experiment the gold balls were fired from an air cannon so that the incoming velocity and spin rate of the ball could be precisely controlled. It is of interest to determine if there ...
