The Critical Mass Energy Project was formed by Ralph Nader in 1974 as a national anti-nuclear umbrella group. It was probably the largest national anti-nuclear group in the United States, with several hundred local affiliates and an estimated 200,000 supporters. Part of Nader's support comes from a Green agenda and the belief that "the most important office in America for anyone to achieve is full-time citizen." The organization's main efforts were directed at lobbying activitie…

- https://en.wikipedia.org/wiki/Mass
Mass is the quantity of matter in a physical body.It is also a measure of the body's inertia, the resistance to acceleration (change of velocity) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often ...

Energy density. In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. It may also be used for energy per unit mass, though a more accurate term for this is specific energy (or gravimetric energy density). Often only the useful or extractable energy is measured, which is to say that ...

Mass-energy equivalence - Energy Education
https://energyeducation.ca/encyclopedia/Mass-energy_equivalenceThe sun produces its energy by the conversion of mass into energy through the process of nuclear fusion. Mass-energy equivalence is the famous concept in physics represented mathematically by E = m c 2, which states that mass and energy are one and the same. This idea was not actually put forth by Einstein, but he was the first to describe an ...

The invariant mass of an electron is approximately 9.109 × 10 −31 kilograms, or 5.489 × 10 −4 atomic mass units. Due to mass–energy equivalence, this corresponds to a rest energy of 0.511 MeV. The ratio between the mass of a proton and that of an electron is about 1836.
