Conservation of energy in a CM system moving at constant velocity

[QUOTE="Leo Liu, post: 6448213, member: 660839"] My book uses ##1/2m_1v_{1c}^2+1/2m_2v_{2c}^2=1/2m_1v_{1c}'^2+1/2m_2v_{2c}'^2## to show that the angles of deflection of the collision between two particles are the same in the centre of mass frame. However, I am doubtful that one can apply the conservation of energy to a "moving" system because the kinetic energies of the same object measured at different observers are different. Is this method valid? [/QUOTE]
