equivalence principle

n.
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.

Why does the coupling of the gravitational force to the SM satisfy the equivalence principle to such a high accuracy?
A form of equivalence principle was proposed by Derek Paul [6], and when it is applied to the potential energy (4) yields
General relativity's strong equivalence principle states that gravity should have the same effect on this binding energy as it would on an equivalent amount of mass.
The system gives the scientists the best opportunity yet to discover a violation of a concept called the Equivalence Principle.
In a scenario such as this, to "make up for" any contaminant that might fail to meet the appropriate standard for a period of time, an equivalence principle should be established that allows such trade-offs to be made.
More on inertial frames and introduction to the equivalence principle lead us into inertial forces and, finally, the bending of light by gravity.
Testing for the constancy of the fundamental constants has proven to be an efficient test of Einstein equivalence principle that can be performed on astrophysical scales.
General relativity is established on two principles (Einstein et al 1923, Einstein 1954), namely: 1) Einstein's equivalence principle, which requires the Einstein-Minkowski condition that a free falling point-like particle in a gravitational field is along a geodesic and results in a co-moving local Minkowski space; and 2) the principle of general relativity, that is "The law of physics must be of such a nature that they apply to systems of reference in any kind of motion.
Wilkinson, New test of equivalence principle from lunar laser ranging, Phys.
This equivalence principle between the inertial and gravitational masses, introduced in classical physics by Galileo Galilei and in modern physics by Albert Einstein, has been confirmed with a very high level of accuracy.
18], do not contradict the existing Eotvos type measurements [11], which have confirmed the equivalence principle with the accuracy of the order of [10.
Abstract: The equivalence principle is at the heart of the geometrisation of gravity and one of the building block of general relativity.
