Okey thank you for your answer. Is this the equation you are referring to? E = p^2 c^2 + m^2 c^4 So if one uses " the invariant rest mass" does it imply the center of mass frame of reference of one of the particles? If that is the case, does that imply that the energy of the particles...

Homework Statement Two particle P and Q each of restmass m0 and moving in collision course at 2/3c in the laboratory frame of reference. In the same collision but in particle P's frame of reference, P is at rest. Homework Equations As the total energy of the particles depends on the frame...
