Definitions specific to this category can be found in Definitions/Coefficient of Restitution.
Let two solid bodies $B_1$ and $B_2$ be in collision.
Let the components of the relative velocities of $B_1$ and $B_2$ in the direction of their common normal be respectively:
- $\mathbf u_1$ and $\mathbf u_2$ before the collision
- $\mathbf v_1$ and $\mathbf v_2$ after the collision.
By Newton's Law of Restitution:
- $\mathbf v_2 - \mathbf v_1 = -e \paren {\mathbf u_2 - \mathbf u_1}$
The coefficient $e$ is known as the coefficient of restitution.
