... One useful result: for elastic collisions, the magnitude of the relative velocity is the same before and after the collision: |v1,i – v2,i | = |v1,f – v2,f | (This is true for elastic collisions in 2 and 3 dimensions as well). An important case is a particle directed at a stationary target (v2,i = ...
