    In an elastic collision, the relative speed of separation of colliding objects is same as the relative speed of approach of the two. If the speeds of approach of the two objects are
    v1,v2v_{1}, v_{2}v1,v2 and the speeds of separation are v1′,v2′v_{1}^{\prime}, v_{2}^{\prime}v1,v2 respectively, then v1+v2=v1′+v2′v_{1}+v_{2}=v_{1}^{\prime}+v_{2}^{\prime}v1+v2=v1+v2
    Also the linear momentum of colliding system is always conserved, both for elastic and inelastic case since there is no external force acting on
    the system
