coefficient of restitution

coefficient of restitution

dimensionless (no units) number representing the ratio of separation velocity to approach velocity after impact of two bodies or objects. Dependent on elasticity of the objects. For example, during impact of a golf ball on a golf club face, ball and club deform and then rebound, which means that the ball increases its velocity. Likewise with a ball and racquet strings.

The coefficient of restitution quantifies the extent to which a perfect collision is modified by the material properties of the colliding objects.
Particularly, the coefficient of restitution would depend on the amount of deformation of the foot and the ball at impact.
The ball demonstrates a higher forward velocity compared with the foot velocity, depending on the coefficient of restitution (Wesson 2002).
In the case of the model (6), the coefficient of restitution is equal to 0.
In this case the coefficient of restitution of the velocity e does not depend on the pre-impact velocity and is determined by
This means that children were able to hit the LC balls harder despite the smaller coefficient of restitution of the LC balls.
The slower LC balls are manufactured to have a lower coefficient of restitution than SC balls, and consequently they have a lower rebound height (Wilson, 2010).

Summating the above diverse facts it could be stated that further research to evaluate of the coefficient of restitution at a particle collisions is required.
