coefficient of restitution


Also found in: Acronyms, Encyclopedia, Wikipedia.

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.

According to the classical theory of impact, coefficient of restitution e can be calculated from the following equation:
The coefficient of restitution was chosen to be fxed at e = 0 for the least-square reconstruction.
It is important to notice at this point that the coefficient of restitution (or elasticity, as used throughout this paper) is a property of collisions, not objects.
It would be advisable that future research take into account the physical differences between SC and LC balls, such as mass, diameter, and coefficient of restitution, in order to determine their influence on corresponding performance variables.
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.
To accomplish this, we will assume that the shock pulses are roughly half sine shaped and that the coefficient of restitution is 0.
He assumes, for example, that the collision between a bat and a ball has the same coefficient of restitution as that measured officially by firing a baseball at 85 feet per second at a wall of ash.
foot] = velocity of the foot, M = effective striking mass of the leg, m = mass of the ball and l = the coefficient of restitution.
Crosslinking polybutadiene with metals salts of either acrylic acid or methacrylic acid results in very hard rubber with high compression and high coefficient of restitution.
Sports Authority, the nation's premier full-line sporting goods retailer, today announces the availability of Batted Ball Coefficient of Restitution (BBCOR) baseball bats at all 462 Sports Authority locations.
It is expressed as the coefficient of restitution, or COR, the ratio of relative velocity after impact to that before impact.
