Noun
(physics) the mass of a body as measured by its gravitational attraction for other bodies
Source: WordNetGravitational lensing observations of galaxy clusters allow direct estimates of the gravitational mass based on its effect on light coming from background galaxies, since large collections of matter (dark or otherwise) gravitationally deflect light. Source: Internet
As of 2009, the Earth's mass in kilograms is only known to around five digits of accuracy, whereas its gravitational mass is known to over nine significant figures. Source: Internet
General relativity models gravity as a curvature within space-time that changes as a gravitational mass moves. Source: Internet
At high speeds, relativistic mass always exceeds gravitational mass. Source: Internet
By finding the exact relationship between a body's gravitational mass and its gravitational field, Newton provided a second method for measuring gravitational mass. Source: Internet
Inertial vs. gravitational mass Although inertial mass, passive gravitational mass and active gravitational mass are conceptually distinct, no experiment has ever unambiguously demonstrated any difference between them. Source: Internet
