:Until someone who understands this turns up, you could do worse than read Mass # Inertial and gravitational mass.
22.
Unlike the parameter m, interpreted as the attractive gravitational mass of the drainhole, the parameter n has no obvious physical interpretation.
23.
That would be enough to give us a flat universe, one with just enough gravitational mass to balance the current expansion.
24.
This is true even when relativistic effects are considered, so long as inertial mass, not rest mass, is equal to gravitational mass.
25.
Gravitational mass is the mass related to F g = mg or F g = Gm 1 m 2 / r 2.
26.
Gravitational mass is measured by comparing the force of gravity of an unknown mass to the force of gravity of a known mass.
27.
In these descriptions, the distinction is purely a matter of convenience; inertial and gravitational mass are different ways of describing the same behaviour.
28.
:: : Perhaps the gravitational mass and inertial mass could theoretically be decoupled, with only the gravitational mass remaining in the black hole.
29.
By finding the exact relationship between a body's gravitational mass and its gravitational field, Newton provided a second method for measuring gravitational mass.
