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...

The word "mass" has two meanings in special relativity: invariant mass (also called rest mass) is an invariant quantity which is the same for all observers...

of the conserved mass if the mass being measured is the invariant mass (i.e., invariant mass is both conserved and invariant). The mass–energy equivalence...

which is independent of the composition of the matter. Rest mass, also called invariant mass, is a fundamental physical property that is independent of...

particle physics, the electron mass (symbol: me) is the mass of a stationary electron, also known as the invariant mass of the electron. It is one of the...

two reference frames. The mass of an object as measured in its own frame of reference is called its rest mass or invariant mass and is sometimes written...

particle physics, a massless particle is an elementary particle whose invariant mass is zero. At present the only confirmed massless particle is the photon...

kinds of mass are defined: rest mass (invariant mass), and relativistic mass (which increases with velocity). Rest mass is the Newtonian mass as measured...

relationship between mass and energy. "Relativistic mass" is a deprecated term. The term "mass" by itself refers to the rest mass or invariant mass, and is equal...

four-momentum gives a Lorentz invariant quantity equal (up to factors of the speed of light c) to the square of the particle's proper mass: p ⋅ p = η μ ν p μ p...

vacuum, accounts for almost 99% of the proton's mass. The rest mass of a proton is, thus, the invariant mass of the system of moving quarks and gluons that...

energy value. Also conserved, and invariant to all observers, is the invariant mass, which is the minimal system mass and energy that can be seen by any...

energy of a particle collision approaches infinity. It differs from the invariant mass as usually understood because the latter includes the 'clothing' of...

gives the rest mass (invariant mass) of the system: m 0 = E 0 c 2 . {\displaystyle m_{0}={\frac {E_{0}}{c^{2}}}.} The invariant mass of the system is...

{\displaystyle s} is also known as the square of the center-of-mass energy (invariant mass) and t {\displaystyle t} as the square of the four-momentum transfer...

the electron has spin 1/2. The invariant mass of an electron is approximately 9.109×10−31 kg, or 5.489×10−4 Da. Due to mass–energy equivalence, this corresponds...

The transverse mass is a useful quantity to define for use in particle physics as it is invariant under Lorentz boost along the z direction. In natural...

A gyrovector space is a mathematical concept proposed by Abraham A. Ungar for studying hyperbolic geometry in analogy to the way vector spaces are used...

presented as being based on just two postulates: The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference...

total mass moving at the speed of the center of mass. The kinetic energy of the system in the center of momentum frame is a quantity that is invariant (all...

relativistic energy) of a particle or compound object, is also the invariant mass (times the scale-factor speed of light squared). It is also the reference...

second law, with mass fixed, is not invariant under a Lorentz transformation. However, it can be made invariant by making the inertial mass m of an object...
