Coefficient of restitution ( two objects)
Description
The 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 object, in this case the definition is assumed to be with respect to collisions with a perfectly rigid and elastic object.In the case of a one-dimensional collision involving 2 objects, Object A and Object B, the coefficient of restitution is related to the velocities of the objects before and after the impact..
