The 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 … See more Line of impact – It is the line along which e is defined or in absence of tangential reaction force between colliding surfaces, force of impact is shared along this line between bodies. During physical contact between bodies … See more In the case of a one-dimensional collision involving two objects, object A and object B, the coefficient of restitution is given by: • $${\displaystyle v_{\text{a}}}$$ is the final speed of object A … See more • Bouncing ball • Collision • Damping capacity • Resilience See more The equations for collisions between elastic particles can be modified to use the COR, thus becoming applicable to inelastic collisions, as well, and every possibility in between. • $${\displaystyle v_{\text{a}}}$$ is the final velocity of the first … See more • Wolfram Article on COR • Bennett & Meepagala (2006).
