the principle that the linear momentum of a system has constant magnitude and direction if the system is subjected to no external force.
- Conservation of momentum
noun 1. the principle that the total linear or angular momentum in any isolated system is constant, provided that no external force is applied conservation of momentum A conservation law stating that the total linear momentum of a closed system remains constant through time, regardless of other possible changes within the system.
- Conservation of parity
noun 1. the principle that the parity of the total wave function describing a system of elementary particles is conserved. In fact it is not conserved in weak interactions
noun 1. a member of a Protestant denomination (Conservative Baptist Association of America) organized in Milwaukee, Wisconsin, in 1948.
- Conservative evaluation
Under this parallel evaluation strategy, no evaluation is started unless it is known to be needed. Opposite of speculative evaluation.
