WebApr 3, 2015 · Photons are said to have zero "rest mass", ie no mass when they are at rest (stationary). But photons are never stationary, so this really has no physical meaning. That they would have no mass at rest is required by relativity or else their energy when … WebSuch a couple of objects would accelerate without limit (except a relativistic one); however, the total mass, momentum and energy of the system would remain zero. This behavior is completely inconsistent with a common-sense approach and the expected behavior of "normal" matter.

For single particles, the rest mass is simply the energy of the particle at rest. For composite systems, we can define the "mass" of the system as E^2-p^2 where E is the total energy of the system, and p is the total momentum, however, … graham cuthbertson

WebYou're confusing mass with weight. Say, somewhere in space, there's a ball, and nearby there's no other sun/planet/anything. Then that ball will experience no force and thus would appear to have no weight. but it will still have mass. Weight is a force that a mass experiences due to gravity. mass is due to atoms and molecules.
