Determine the coefficient of restitution between two colliding objects from their approaching and separating velocities — a measure of how elastic (bouncy) the impact is.
输入碰撞前后两物体速度,求恢复系数。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Coefficient of restitution | e = |v_rel,after| / |v_rel,before| | Newton's impact law, 1686 / Poisson 1817 |
| Range | e=1 elastic, e=0 perfectly inelastic | Impact mechanics texts |
