| Conservation of Energy. Article courtesy of http://RacingSecrets.com In physics, a conservation law states that a particular physical quantity cannot change during the evolution of an isolated physical system. The following are conservation laws that have never been shown inexact: * conservation of energy (encompasses mass) * conservation of momentum * conservation of angular momentum * conservation of electric charge * conservation of color-charge? There is an important connection between conservation laws and the invariance of physical laws with respect to certain transformations and. For instance, in can be shown that time invariance implies that energy is conserved, that translational invariance implies that momentum is conserved and that rotational invariance implies that angular momentum is conserved. Some approximate conservation laws hold in many circumstances, but exceptions to them have been observed.
