Question
Which physical quantity is conserved in a collision (in
the absence of external forces)? ÂSolution
In any collision, total momentum is conserved if no external force acts.  Momentum p = mv is a vector quantity.  This is based on Newton’s third law.  Energy may not be conserved in inelastic collisions, but momentum is.
