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

mass-energy equation — ˈ ̷ ̷| ̷ ̷ ̷ ̷ ̷ ̷ noun : an equation for the interconversion of mass and energy: E = mc2 where E is energy in ergs, m is mass in grams, and c is the velocity of light in centimeters per second called also Einstein equation; compare conservation… … Useful english dictionary
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
Conservation of energy — This article is about the law of conservation of GPE in physics. For sustainable energy resources, see Energy conservation. Prof. Walter Lewin demonstrates the conservation of mechanical energy, touching a wrecking ball with his jaw. (MIT Course… … Wikipedia
mass — massedly /mas id lee, mast lee/, adv. /mas/, n. 1. a body of coherent matter, usually of indefinite shape and often of considerable size: a mass of dough. 2. a collection of incoherent particles, parts, or objects regarded as forming one body: a… … Universalium

energy, conservation of — Principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant, though it may take different forms (e.g., kinetic energy, potential energy, thermal energy, energy in an electric current,… … 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
