Jul 23, 2015 at 16:05 comment added dmckee --- ex-moderator kitten The problem with taking $\gamma m v$ as "inertia" in relativity is that it is not correct for forces applies transverse to the current direction of motion. See for instance mathpages.com/home/kmath674/kmath674.htm . To go this route you end up with two different relativistic inertias for the same particle (one in the direction of boost and one perpendicular to boost). People have gone that road in the past, and some defined it as clear and useful, but I never mastered it to my own satisfaction.
