Whats the equation for the coefficient of restitution again? Went blank!
Coefficient of Restitution = Speed of Separation = v[sub]1[/sub]-v[sub]2[/sub]

Speed of Approach u[sub]1[/sub]-u[sub]2[/sub]
The Coefficient of Restitution, also known as COR or e, is a dimensionless number that represents the ratio of the final velocity of an object after a collision to its initial velocity. It is a measure of the elasticity of a collision, with a higher COR indicating a more elastic collision and a lower COR indicating a more inelastic collision.
The COR is calculated by dividing the final velocity of an object after a collision by its initial velocity. This value can range from 0 to 1, with 1 representing a perfectly elastic collision and 0 representing a completely inelastic collision.
The COR can be affected by a variety of factors, including the materials of the colliding objects, the surface properties of the objects, and the angle at which the objects collide. Other factors such as temperature and air resistance can also play a role in the COR of a collision.
The COR is an important concept in physics and engineering, as it helps us understand the behavior of objects during collisions. It is also used in sports, such as in determining the bounce of a ball, and in the design of safety equipment, such as helmets and car bumpers.
The Coefficient of Restitution and the Coefficient of Friction are both measures of the interaction between objects, but they are different in their definitions and applications. The COR relates to the elasticity of a collision, while the Coefficient of Friction relates to the resistance to motion between two surfaces in contact. They also have different units of measurement, with the COR being dimensionless and the Coefficient of Friction having units of force.
