    What is E = [itex]\frac{m_{0}c^{2}}{1-v^{2}/c^{2}}[/itex]

    Hi Lizwi,

    I think you are missing a square root in the denominator? The expression:
    [tex]E= \gamma m c^2 = \frac{mc^2}{\sqrt{1-v^2/c^2}}[/tex]
    Is the relativistic expression for the total energy of a moving body.

    What Nabeshin said
    You can also drop the 0 from the [itex]m_0[/itex], I've not seen the term 'rest mass' used since highschool. Once you're out of highschool it simply becomes mass as far as I know :p

    its a term that pops up in the four-momentum if you use the convention that x0 = ct rather that x0 = t

    if you use x0 = t then you just get p0 = gamma*m
