It is the extension of mass–energy equivalence for bodies or systems with non-zero momentum. It can be written as the following equation: Deriving relativistic momentum and energy 3 to be conserved. This is why we treat in a special way those functions, rather than others. This point of view deserves to be emphasised in a pedagogical exposition, because it provides clear insights on the reasons why momentum and energy are deﬁned the way Relativistic Energy The kinetic energy of an object is defined to be the work done on the object in accelerating it from rest to speed v. (2.1.13) K E = ∫ 0 v F d x Using our result for relativistic force (Equation 2.1.12) yields Basically, you start with an object at rest, integrate the work-energy theorem, apply the form of Newton's Second Law that says F = dp/dt, and use relativistic momentum: [tex]K = \int {F dx} = \int {\frac {dp}{dt} dx} = \int {\frac {dx} {dt} \frac {dp}{dv} dv} = \int {v \frac {dp}{dv} dv} = \int {v \frac {d}{dv} ( \gamma mv ) dv } [/tex] Lagrangian dynamics provides a way to derive the formula for relativistic linear momentum rather than just assuming it. If K is the kinetic energy of a system and V is the potential energy then the Lagrangian of the system is defined as L = K − V The four quantities ( E c,px,py,pz) ≡ ( E c,→ p) form a 4-vector, called, rather unimaginatively, the energy -momentum 4-vector .

I'm mathematically putting it down - gotta get up to get down. Relativistic momentum is defined by p = mv(1 - v^2/c^2)^-.5 You need to use implicit derivation to take the derivative of this with respect to t. Thus you should have dp/dt and dv/dt term. Once you are finished getting the derivative and combining terms you should end up with dv/dt = F(1-v^2/c^2)^3/2 /m begins to make the transition from non-relativistic to relativistic: ρ = µ eM(3π2)2 5 12π2 3 m ec ¯h 3.
