37. Coefficient of Restitution, mathematical value; defined by Isaac Newton in 1867. In physics, the ratio of the difference between the speeds of two colliding objects, as measured after and before their impact. For most collisions between two objects—say an Eastern Cottontail rabbit and a car on its way somewhere down the mountain—the coefficient of restitution will range between 0 and 1. The higher this value climbs, the greater the elasticity of the collision will be. In a collision with a COR of 1, the entirety of the energy each object was carrying at the time of impact is transferred to the other, and they will trampoline apart. The lower this value drops, the greater the inelasticity of the collision will be. In a collision with a COR of 0, the entirety of the energy each object was carrying at the time of impact is lost or absorbed, and both come to a complete stop. I know it happened sometime before the cock crowed, but not much. No one collected measurements.
