Conservation of Momentum in Relativity

    I had gotten into this discussion in several places and didn't want to do the math out. But I've decided that it's time to stop being lazy. I just completed deriving the conservation relations for angular momentum and linear momentum for conservative systems.

    I put it here


    In that page three relations are derived. For a conservative system

    (1) The total angular momentum is conserved

    (2) The total linear momentum is conserved

    (3) The "center of mass/energy vector" R is related to P, the total momentum of a conservative system, by P = M(dR/dt) = MV where M = "Total (relativistic) mass = "total energy"/c^2

    Also "center of mass vector" = "center of energy vector"
