noun, Physics, Chemistry.
any law stating that some quantity or property remains constant during and after an interaction or process, as conservation of charge or conservation of linear momentum.
Any of various principles, such as the conservation of charge and the conservation of energy, that require some measurable property of a closed system to remain constant as the system changes. Conservation laws can be directly related to principles of symmetry. See also invariance, Noether’s theorem.
noun, Physics. 1. the principle that the total angular momentum of a system has constant magnitude and direction if the system is subjected to no external force.
noun, Physics. 1. the principle that the total baryon number remains constant in all processes involving the interaction of elementary particles.
noun, Physics. 1. the principle that the total electric charge of a system is constant. noun 1. the principle that the total charge of any isolated system is constant and independent of changes that take place within the system conservation of charge A conservation law stating that the total electric charge of a closed system […]
noun, Physics. 1. the principle that in a system that does not undergo any force from outside the system, the amount of energy is constant, irrespective of its changes in form. noun 1. the principle that the total energy of any isolated system is constant and independent of any changes occurring within the system apparently […]
