WHAT DOES REST MASS MEAN IN ENGLISH?

Invariant mass

The invariant mass, rest mass, intrinsic mass, proper mass, or simply mass, is a characteristic of the total energy and momentum of an object or a system of objects that is the same in all frames of reference related by Lorentz transformations. If a center of momentum frame exists for the system, then the invariant mass of a system is simply the total energy divided by the speed of light squared. In other reference frames, the energy of the system increases, but system momentum is subtracted from this, so that the invariant mass remains unchanged. Systems whose four-momentum is a null vector have zero invariant mass, and are referred to as massless. A physical object or particle moving faster than the speed of light would have space-like four-momenta, and these do not appear to exist. Any time-like four-momentum possesses a reference frame where the momentum is zero, which is a center of momentum frame. In this case, invariant mass is positive and is referred to as the rest mass. If objects within a system are in relative motion, then the invariant mass of the whole system will differ from the sum of the objects' rest masses.

Definition of rest mass in the English dictionary

The definition of rest mass in the dictionary is the mass of an object that is at rest relative to an observer. It is the mass used in Newtonian mechanics.
