I thought zero rest-mass particles also produced some gravity force, just less of it? ❋ Unknown (2010)
In the special case where O and S are in a state of relative rest the mass of S measured by O is called the rest-mass, which one often designates mo. ❋ Flores, Francisco (2007)
Lange begins his interpretation by arguing that rest-mass is the only real property of physical systems. ❋ Flores, Francisco (2007)
Typically, in these types of reactions, the potential energy that “contributes” to the rest-mass of one (or possibly) more of the reactants is transformed in a non-controversial way to the kinetic energy of the products. ❋ Flores, Francisco (2007)
The rest-mass of S is a measure of the inertia of S, i.e., of the tendency of ❋ Flores, Francisco (2007)
In the case of the ideal gas, as we have seen, when the gas sample is heated and its inertial mass concurrently increases, this increase in rest-mass is not a result of the gas somehow being suddenly (or gradually) composed of molecules that are themselves more massive. ❋ Flores, Francisco (2007)
However, if Lange adopts Lorentz-invariance as both a necessary and sufficient condition for the reality of a physical quantity, then he is committed to the view that rest-energy is real for the very same reasons he is committed to the view that rest-mass is real. ❋ Flores, Francisco (2007)
Finally, we can now appreciate why no interpretation of mass-energy equivalence can explain why the rest-mass of the constituents of a physical system contributes to that system's rest-energy, or why the energy of the constituents contributes to the rest-mass of the system. ❋ Flores, Francisco (2007)
Furthermore, the photons that are the products in reaction have zero rest-mass. ❋ Flores, Francisco (2007)
In other words, one can explain the change in mass and energy in reaction by saying (i) that the potential and kinetic energies of the nucleons that make up the 7Li nucleus contribute to its rest-mass and (ii) that the vast amount of energy of the α-particles was not “created” in the reaction, or ❋ Flores, Francisco (2007)
Let us suppose for simplicity that there are n molecules each of rest-mass m. ❋ Flores, Francisco (2007)
Thus, from now on, we will use E to designate rest-energy and m to designate rest-mass. ❋ Flores, Francisco (2007)
Bondi and Spurgin must explain the rest-mass of the 7Li in the familiar way, as arising from both the sum of the rest-masses of the nucleons, and the mass-equivalents of their energies. ❋ Flores, Francisco (2007)
However, in several other places, for example when Lange argues for the reality of the Minkowski interval (p. 219, 2002) or when he argues for the reality of rest-mass (p. 223, 2002), Lange implicitly uses Lorentz invariance as a sufficient condition for the reality of a physical quantity. ❋ Flores, Francisco (2007)
The rest-mass is related to the relativistic mass by the equation: ❋ Flores, Francisco (2007)
Before the collision, the rest-mass of the system is simply the sum of the rest-masses of the electron and positron plus the mass-equivalent of the total kinetic energy of the particles. ❋ Flores, Francisco (2007)
The simplest form of the Standard Model assumes that neutrinos, like photons and gluons, have zero rest-mass. ❋ Unknown (2004)
One discussed the then-current evidence for a neutrino with a huge 17 keV rest-mass (see _Analog_, December, 1991). ❋ Unknown (2004)
