It means "obeying the Lorentz transformation" which is necessary if your physics covers different inertial frames (as for example, a fast moving subatomic particle and a lab apparatus assumed at rest). This means that energy depends on relative speed.Honorable_Death said:can anyone explain to me wha relativistic is?
Seems to me that when someone is using that term they are referring to the sum of kinetic energy + rest mass energy.Honorable_Death said:wow sorry i dont no what was wit me when i wrote that forum, but what i ment to ask was can anyone explain to me what relativistic energy is?
Energy (sometimes referred to as "total energy") is an undefined quantity. Its a number associated with a system and this number is a constant. Energy is made up of various forms of energy each of which are well defined. One form is kinetic energy, one is mass-energy, one is potential energy etc. The quantityEl Hombre Invisible said:That's just energy isn't it?
That's true so long as the body is not under stress and has zero potential of position.El Hombre Invisible said:Relativistic energy due to observable differences in total energy due to differing reference frames. The total energy of an object is given by the root of (pc)^2 + (mc)^2, so relativistic energy is dependant on momentum, which may change frame to frame.
