Question

Define coefficient of restitution​

Answer 1

The coefficient of restitution (COR), also denoted by (e), is the ratio of the final to initial relative velocity between two objects after they collide. It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision.

Answer 2

Coefficient of restitution is defined as the ratio of relative velocity after collision to the relative velocity before collision. If u

1

& u

2

are the velocities of 2 bodies before collision & v

1

& v

2

are velocities after collision then coefficient of restitution,
