Conservation law

Jump to navigation Jump to search


In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves. Any particular conservation law is a mathematical identity to certain symmetry of a physical system. A partial listing of conservation laws that are said to be exact laws, or more precisely have never been shown to be violated:

There are also approximate conservation laws. These are approximately true in particular situations, such as low speeds, short time scales, or certain interactions.
