Attributive form of conservation law, noun
Any of several laws that hold that some physical property remains constant in a closed system regardless of other changes that take place
law of conservation of energy
The law stating that the total amount of energy in any isolated system remains constant, and cannot be created or destroyed, although it may change forms
conservation law
or law of conservation In physics, the principle that certain quantities within an isolated system do not change over time. When a substance in an isolated system changes phase, the total amount of mass does not change. When energy is changed from one form to another in an isolated system, there is no change in the total amount of energy. When a transfer of momentum occurs in an isolated system, the total amount of momentum is conserved. The same is true for electric charge in a system: charge lost by one particle is gained by another. Conservation laws make it possible to predict the macroscopic behaviour of a system without having to consider the microscopic details of a physical process or chemical reaction
law of conservation of energy
basic law of nature which claims that energy is neither created nor wasted but rather changes form, basic law of physics
law of conservation of mass
basic law of nature which claims that mass is neither created nor wasted but rather changes form
