Does inertia apply to EVERYTHING in the universe? Even subatomic particles? Or is there a certain mass limit where something no longer has the property of inertia?

Quantumgravity said:Does inertia just mean that it takes energy to move a mass?
arunma said:Of course, there are some particles which physicists believe do not have mass. Neutrinos are an example that comes to mind.
jtbell said:Nope, for the past several years it's been widely accepted that neutrinos do have a very small mass (a few eV or less). It's studied via neutrino oscillations.
The only massless particles now, so far as I know, are the photon, the gluons, and the graviton (if it exists).
But why don't photons have kinetic energy?
