• ## Invariant mass - Wikipedia

en.wikipedia.org/wiki/Invariant_mass The invariant mass, rest mass, intrinsic mass, proper mass, or in the case of bound systems simply mass, is the portion of the total mass of an object or system of objects that is independent of the overall motion of the system. More precisely, it is a characteristic of the system's total energy and momentum that is the same in all frames of reference related by Lorentz transformations.

• ## particle physics - What determines invariant mass ...

physics.stackexchange.com/questions/328357/what-determines-invariant-mass Very succinctly: a system's total energy, as measured from its rest frame, is the invariant mass. The rest frame is determined by the frame wherein a system's total momentum is nought. You are probably a little confused by the photon and other so-called massless objects.

phys.libretexts.org/Bookshelves/Particle_Physics/.../9.02%3A_Invariant_Mass No headers. One of the key numbers we can extract from mass and momentum is the invariant mass, a number independent of the Lorentz frame we are in $W^2c^4 = (\sum_i E_i)^2 - (\sum_i {\vec{p}}_i)^2 c^2.$ This quantity takes it most transparent form in the center-of-mass, where $$\sum_i {\vec{p}}_i = 0$$.
• ## Invariant Mass vs Proper Mass | Physics Forums

www.physicsforums.com/threads/invariant-mass-vs-proper-mass.1661 Invariant mass is the more general name which applies to systems of particles. And that, of course, means it applies to single particles as a special case. The name "invariant" is used over "rest" since there's nothing which is at rest. Only thing they have in common in this respect is a zero-momentum frame,

This is the "m" both in Newton's second law of motion, F=ma, and in Einstein's equation, E=mc 2 (in which E must be interpreted as the energy of the ...
