Newtonian-Relativistic Comparisons

Return to Relativity

To gain an intuitive insight into general relativity, it is helpful to have a heuristic correspondence between relativistic quantities and equations and their Newtonian counterparts. In this section we will list relativistic quantities with their Newtonian counterparts.
