You hear a lot of people talk about how your weight changes based on how you're accelerating, but your mass stays the same, but according to Einstein, mass and energy are interchangeable. So if you were going very fast, and had a lot of kinetic energy relative to some fixed point, would your mass also be greatly increased relative to that frame? Basically, is mass relative like energy, speed, time, etc.?

Every particle having a non zero rest mass has a rest energy:
Er = (M0*C^2)
Er = rest energy
M0 = rest mass
C^2 = speed of light squared.
When a particle is moving with respect to an observer, it has a total energy = kinetic + rest energy given by:
E = (M0*C^2)/sqrt[1-(V/C)^2]
sqrt[ ] stands for square root of the argument between the two symbols [ ].
So, the equivalent mass is:
E/C^2 = M = (M0)/sqrt[1-(V/C)^2]
it is easy to see that the mass corresponding to the energy of a moving particle increases to infinite as its speed V approaches the speed of light C.
