How is the relativistic energy concept stated?

The relativistic expression for kinetic energy is obtained from the work-energy theorem. This theorem states that the net work on a system goes into kinetic energy. If our system starts from rest, then the work-energy theorem is Wnet = KE. Relativistically, at rest we have rest energy E0 = mc2.

What is relativistic mass Quora?

Relativistic mass is inertial mass that is added over rest mass due to velocity, ie the natural phenomenon of relativity.

Why relativistic mass is important?

It explains simply and quantitatively why a body subject to a constant acceleration cannot reach the speed of light, and why the mass of a system emitting a photon decreases. In relativistic quantum chemistry, relativistic mass is used to explain electron orbital contraction in heavy elements.

What are the consequences of the special theory of relativity?

Specifically, Special Relativity showed us that space and time are not independent of one another but can be mixed into each other and therefore must be considered as the same object, which we shall denote as space-time. The consequences of space/time mixing are: time dilation. and length contraction.

What is the relativistic mass in these equations?

Relativistic mass m in these equations is a kind of a stub of a four-vector.These equations are based on a naive but unfounded requirement that masses in relativity must have the property of additivity. They are based on the purely non-relativistic concept of mass as the measure of inertia.

Is there an invariant mass in old and new theories?

A paper from 1976 (Eriksen and Voyenli, “The Classical and Relativistic Concepts of Mass,” Found. Phys. 6, 115–24 (Feb.1976)) pointed that there is an invariant mass in the old and new theories but only in the old theory a sum is conserved.

When did the relativistic mass movement start?

The “movement” against relativistic mass was started by Adler in 1987 with Does Mass Really Depend on Velocity, Dad? (his answer, ” actually no, but don’t tell your teacher “). It got a boost from Okun’s two 1989 papers.

What is Adler-Okun’s argument against relativistic mass?

Here is the gist of Adler-Okun’s argument as expressed by Okun in 2008:” The concept of relativistic mass, which increases with velocity, appears only in the framework of a language which is not compatible with the standard language of relativity theory and therefore impedes the understanding and learning the theory by beginners…
