Noun
coefficient of restitution (plural coefficients of restitution)
(physics) Ratio of the final to the initial relative velocity between two objects after they collide
A perfectly elastic collision has a coefficient of restitution of one; a perfectly inelastic collision has a coefficient of restitution of zero. Source: Internet
In this case, coefficient of restitution does not equal one. Source: Internet
In this case, the coefficient of restitution equals one. Source: Internet
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. Source: Internet
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. Source: Internet
