In a typical collision the interaction first compresses both bodies and
then acclerates them. The amount of compression and acceleration of the
bodies need not be same. In come cases the direction of acceleration can
be opposite to the direction of motion so the speed is reduced.

Sometimes one of the bodies is so massive that the acceleration is too
small to be detected, e.g. when someting falls to the ground.
