Definition: Rest Mass |
Rest MassNoun1. (physics) the mass of a body as measured when the body is at rest relative to an observer, an inherent property of the body. Source: WordNet 1.7.1 Copyright © 2001 by Princeton University. All rights reserved. |

Aerospace | According to relativistic theory, the mass which a body has when it is at absolute rest. Mass increases when the body is in motion according to where m is its mass in motion; m0 is its rest mass; v is the body's speed of motion; and c is the speed of light.Newtonian physics, in contrast with relativistic physics, makes no distinction between rest mass and mass in general.

(From Wikipedia, the free Encyclopedia)
In special relativity, rest mass is an obsolete term used to describe what is today simply referred to as mass. Relativistic mass mr (formerly called "mass", but now called energy) increases with velocity (v), and the rest mass m is the inertial mass at v=0, which corresponds to the classical notion of mass.
When an object is travelling at a velocity v relatively to an inertial reference frame, then the relativistic mass increases according to:
The terms rest mass and relativistic mass can be still be found in elementary textbooks and popularisations of relativity, but their use is depreciated in graduate-level physics.
