equivalence principle
equivalence principlen. A principle central to the theory of general relativity stating that a gravitational field is locally indistinguishable from the effects of an inertial force, such as the acceleration caused by a source of propulsion.equivalence principle
equivalence principle (i-kwiv -ă-lĕns) The principle that, on a local scale, the physical effects of a uniform acceleration of some frame of reference imitates completely the behavior in a uniform gravitational field. This equivalence of the two frames of reference was introduced by Albert Einstein in his general theory of relativity. It is a generalization of the observed direct proportionality between gravitational and inertial mass.equivalence principle[i′kwiv·ə·ləns ‚prin·sə·pəl] (relativity) In general relativity, the principle that the observable local effects of a gravitational field are indistinguishable from those arising from acceleration of the frame of reference. Also known as Einstein's equivalency principle; principle of equivalence. ThesaurusSeeprinciple of equivalence |
