In a one-dimensional collision between two particles, their relative velocity is `vec(v)_(1)` before the collision and `vec(v)_(2)` after the collision.

In a one-dimensional collision between two particles, their relative velocity is vecv_(1) before the collision and vecv_(2) after the collision

In an elastic one dimensional collision between two particles the relative veloctiy of approach before collision is
