coefficient of restitution
Noun
Meaning
coefficient of restitution (plural coefficients of restitution)
(physics) Ratio of the final to the initial relative velocity between two objects after they collide
Examples
A perfectly elastic collision has a coefficient of restitution of one; a perfectly inelastic collision has a coefficient of restitution of zero.
In this case, coefficient of restitution does not equal one.
In this case, the coefficient of restitution equals one.
Then the kinetic energy of bodies reduces to its minimum during this phase and may be called a maximum deformation phase for which momentarily the coefficient of restitution becomes one.
This is the line along which internal force of collision acts during impact and Newton's coefficient of restitution is defined only along this line.
