Answer to Question #204044 in Mechanics | Relativity for Xavier

Question

Build the relation between relativistic momentum and energy

Answer 1

energy–momentum relation, or relativistic dispersion relation, is the relativisticequation relating total energy (which is also called relativistic energy) to invariant mass (which is also called rest mass) and momentum. It is the extension of mass–energy equivalence for bodies or systems with non-zero momentum. It can be

written as the following equation:

$E^2=(PC)^2+(M_0C^2)^2$

Thi is known as energy Momentum relation
