mass dilation, relativistic energy.
The Attempt at a Solution
Does Einstein's E=mc2 involve mass and energy as relative values? or does the equation mc2=moc2+Ek ie: the same eqn just with mass dilation and relativistic energy involved...?
I'm doing a presentation and I want to say that the second eqn above is the relativistic one and that einstein's one is the general one, but I have conflicting sources. If einstein's E=mc2 is relative then why doesn't it include mass dilation?
