IEVref: 113-03-06 ID: Language: en Status: Standard Term: relativistic mass Synonym1: apparent mass (deprecated) [Preferred] Synonym2: Synonym3: Symbol: Definition: for a particle, its mass when moving in an inertial frameNOTE 1 A particle with rest mass m0 and speed v has a relativistic mass equal to ${m}_{0}/\sqrt{1-{v}^{2}/{c}_{0}^{2}}$, where c0 is speed of light. When the speed v is non-zero, the relativistic mass is greater than the rest mass. NOTE 2 In the theory of relativity, the term “mass” generally means relativistic mass.
