conservation law | law | A quantity that remains unchanged in the course of the evolution of a dynamical system. There are seven known quantities that are conserved: energy (including mass), momentum, angular momentum (including spin), charge, electron-family number, muon-family number, and baryon-family number. | |
conservation of momentum | conservation law | momentum | The principle that the linear momentum of a system (in Newtonian mechanics, mass times velocity) remains the same as long as no external force acts. |
