Definition: for a particle, its mass when moving in an inertial frame

NOTE 1 A particle with rest mass m0 and speed v has a relativistic mass equal to m 0 / 1− v 2 / c 0 2 MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaad2gadaWgaaWcba GaaGimaaqabaGccaGGVaWaaOaaaeaajugabiaaigdakiabgkHiTerb c92BRbsqUrxAXvxyaGqbciaa=zhadaahaaWcbeqaaiaaikdaaaGcca GGVaGaam4yamaaDaaaleaacaaIWaaabaGaaGOmaaaaaeqaaaaa@475E@ , 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.
