The Lorentz factor in special relativity is used in both cases as follows. One deals with momentum and the other deals with energy. $r'=\gamma{r}, dr'=\gamma{dr}$$\partial{r'}=\gamma\partial{r}$ γ is a function of speed, which in turn is a function of distance (r) and time (t). Then, are γ and r independent of each other? In other words, there is a question as to whether it should be treated as ..
