WebIn physics, the energy–momentum relation, or relativistic dispersion relation, is the relativistic equation 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. WebSep 12, 2024 · Note that the total velocity squared is the sum of the squares of its components, so that ¯ v2 = ¯ v2 x + ¯ v2 y + ¯ v2 z. With the assumption of isotropy, the three averages on the right side are equal, so ¯ v2 = 3¯ v2 ix. Substituting this into the expression for F gives F = Nm¯ v2 3l. The pressure is F / A, so we obtain
