Fundamental laws of physics are based on core principles, including several conservation laws. Energy, linear momentum, angular momentum, and electric charge are quantities that are conserved in isolated systems according to fundamental physical principles.

Conservation means that the total amount of the quantity remains constant over time within a closed system, even though it may be transformed or transferred between different forms or parts of the system. These conservation laws are derived from symmetries in nature and are cornerstones of physics.

Conservation of energy (first law of thermodynamics) states that energy cannot be created or destroyed, only transformed. Conservation of momentum (linear and angular) arises from Newton’s laws and implies that the total momentum of a system remains constant in the absence of external forces or torques. Conservation of charge states that the net electric charge of an isolated system remains constant.
