We introduce new relativistic mechanics of a material particle, where the rest mass of the particle is not a constant, but a known function of the Lorentz factor, alternative to the relativistic mechanics of Einstein's special relativity, where the rest mass of the particle is a constant. We first introduce a new relativistic linear momentum alternative to the relativistic linear momentum in special relativity, and then we find a new relativistic force law alternative to the relativistic force law in special relativity. After that, we introduce a new relativistic electromagnetic force law alternative to the Lorentz force law in special relativity, and then we use the muon g-2 experiments, done by J. Bailey et al. Nature 268, 301-305 (1977) and G. W. Bennett et al. Phys. Rev. D 73, 072003 (2006), to see whether those experiments are supportive evidence for the new law alternative to the Lorentz force law in special relativity.
