## gravitational mass

[‚grav·ə′tā·shən·əl ′mas]
(physics)
The mass of a particle as it determines the force it experiences in a gravitational field; equal to inertial mass according to the equivalence principle.

The analogous quantity in our nonperturbative simulation is proper separation to gravitational mass, [d.sub.P]/m.
Other parameters of GSA like the gravitational variable G, the active gravitational mass [M.sub.ai], the passive gravitational mass [M.sub.pi], the inertial mass [M.sub.ii], and the acceleration [a.sub.d.sub.i] will be, respectively, computed by other equations.
where the symbols stand for: [MATHEMATICAL EXPRESSION - Gravitational force, NOT REPRODUCIBLE IN ASCII] G - Gravitational constant, [M.sub.A] - Active gravitational mass, [M.sub.P] - Passive gravitational mass, [M.sub.I] - Inertia gravitational mass, R - Euclidean distance between masses [M.sub.A] and, [M.sub.P] [MATHEMATICAL EXPRESSION - Acceleration value NOT REPRODUCIBLE IN ASCII] of object 1.
This has physicists puzzled, but it could be explained if gravitational mass was not the same as inertial mass, which is a paradigm in physics.
In RKD's case, the phenomenological law, showing the possible violation of the equivalence between inertial and gravitational mass, was first searched for as well; then it was translated into its empirical relationship.
In this account, once we have made the interpretation of the causal transportation equations and then, coupled with the dynamical equation, we found the factor 1-[LAMBDA] + [DELTA]; the roll of this factor reduced the inertial energy density and effective gravitational mass density that appears in the system.

In his recent comment , Crowell criticizes one of the experiments, suggested by us , which can demonstrate inequivalence between passive gravitational mass of a composite quantum body and its energy.
Hence, the frequency change of a photon of frequency [v.sub.0] moving relative to a gravitational mass is hv = h[v.sub.0] (1 - GM/r[c.sub.2]).
The notion of gravitational mass of a composite body is known to be non-trivial in general relativity and related to the following paradoxes.
This raises the additional question whether full symmetry also requires the photon to have a positive or negative gravitational mass, as given by
