Hello, I tried a different route to derive relativistic kinetic energy and I cannot see why it doesn't work. Here is my work: 8.00000000000000E+01 RM

Mass Derivation (The Mass Creation Equation) M CT 0 = ≥=ρρ 0, 1 as the ρinitial condition, C the mass creation rate, T the time, a density. Let . V be a second mass creation rate, and . T ' a second mass creation time, defined at a … In classical mechanics, the mass of a moving particle is independent of its velocity. But in special theory of relativity one can see that mass is also relative.

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 . This is a generalization to four dimensions of the notion of ordinary, or 3-vectors. Just like the components of all 3-vectors (like force, momentum, velocity, ) transform like the coordinates are rotated, components of all 4-vectors transform just like the prototype 4-vector (ct,x,y,z) under a Lorentz transformation - the rule which describes how The derivation of special relativity depends not only on these two explicit postulates, but also on several tacit assumptions (made in almost all theories of physics), including the isotropy and homogeneity of space and the independence of measuring rods and clocks from their past history.

in the non-relativistic limit when v is small, the higher order terms not shown are negligible, and the Lagrangian is the non-relativistic kinetic energy as it should be. The remaining term is the negative of the particle's rest energy, a constant term which can be ignored in the Lagrangian.

Energy can exist in many forms, and mass energy can be considered to be one of those forms.

This action is very elegant: it is brieﬂy written in terms of the geometrical quantity ds,ithas a clear physical The relativistic wave equation, the relativistic energy momentum relation, and Minkowski space can all be represented by simpler equations when we understand mass at a deeper level. The kinetic energy of such systems depends on the choice of reference frame: the reference frame that gives the minimum value of that energy is the center of momentum frame, i.e. the reference frame in which the total momentum of the system is zero. This minimum kinetic energy contributes to the invariant mass of the system as a whole. Derivation We derive the expressions for relativistic momentum and mass starting from the Lorentz transform for velocity.

In particular, its value is the same in the frame in which the particle is (at least instantaneously) at rest. In this frame #E=mc^2,vec p=0#, so that in this frame the invariant is #((mc^2)/c)^2-0^2=m^2c^2#
2021-04-12 · Note that at β=0 this supposed kinetic energy is −m 0 c² and at at β=1 this supposed kinetic energy is zero. Negative kinetic energy is of course complete nonsense. Apparently conventional physicists are so set on the formula mv for relativistic momentum that they are willing to accept a derivation of it from nonsense. I have come across a weird integration during derivation of relativistic kinetic energy. Our professor states that i can get RHS out of LHS using integration by parts: $$ \int\limits_0^x \!
