Kinetic energy of two moving objects

  1. Nov 29, 2011 #1
    Assume a body of mass m moving with velocity V1 towards a body with a mass M and its velocity is zero
    The kinetic energy of the first body with respect to the second body is 1/2mV2 in the reference frame fixed to the non moving body
    The kinetic energy of the second body with respect to the first body is 1/2MV2 in the reference frame fixed to the moving body

    There is difference in KE 1/2(M-m)v^2

    Do you think that is a meaningful quantity?
