WebThe Coefficient of Restitution plays a vital role in the design of sports balls. A basketball, for example, bounces more than a tennis ball because less energy is lost by the basketball when it hits the ground. We can determine the percentage of speed that the ball retains after the collision by use of the coefficient of restitution. WebThe coefficient of restitution (COR) of two colliding objects is typically a positive real number between 0.0 and 1.0 representing the ratio of speeds after and before an impact, taken along the line of the impact. An object (singular) is often described as having a coefficient of restitution as if it were an intrinsic property without reference to a second … WebSTEP 2: Form an equation using the coefficient of restitution.
