Conservation of mass — The law of conservation of mass, also known as the principle of mass/matter conservation, states that the mass of an isolated system (closed to all matter and energy) will remain constant over time. This principle is equivalent to the… … Wikipedia

Einstein's mass-energy relation — Relationship between mass (m) and energy (E) in Albert Einstein s special theory of relativity, expressed E = mc2, where c equals 186,000 mi/second (300,000 km/second), the speed of light. Whereas mass and energy were viewed as distinct in… … Universalium

mass, conservation of — ▪ physics principle that the mass of an object or collection of objects never changes, no matter how the constituent parts rearrange themselves. Mass has been viewed in physics in two compatible ways. On the one hand, it is seen as a… … Universalium
Conservation law — For the legal aspects of environmental conservation, see conservation movement. In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves. One particularly… … Wikipedia
Mass in special relativity — incorporates the general understandings from the concept of mass energy equivalence. Added to this concept is an additional complication resulting from the fact that mass is defined in two different ways in special relativity: one way defines… … Wikipedia
