High Speed Energy

    In the equation:

    KE = mc^2 - m0c^2

    (can be seen more cleary: http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/releng.html#c1)

    What does " m0 " stand for?
    And this equation will give me the kinetic and rest mass energy of only a high speed particle???

    Im no expert but i think this is how it is!

    The m0 stand for the particles rest mass (the mass you can look up in a physics book) and m stand for the relativistic mass


    The total energy Etot = EK + m0*c^2 = m*c^2

    Did this help?
