(physics) The or the gravitoelectric field.Novello, M. ? VII Brazilian School of Cosmology and Gravitation, Rio de Janeiro, August 1993] Atlantica Séguier Frontières, 1994, p. 257 ? "In general, a system can have both translational and rotational accelerations, however. It follows from Einstein's principle of equivalence that locally—i.e., to the extent that spacetime curvature can be neglected—gravitational effects are the same as inertial effects; therefore, gravitation can be approximately described in terms of gravitoelectric and gravitomagnetic fields corresponding to translational and rotational inertia, respectively. This is the gravitational Larmor theorem, which is very useful in the post-Newtonian approximation to general relativity. The gravitomagnetic field of a massive rotating body is a measure of its absolute rotation."''Thorne, Kip S. ? [http://einstein.stanford.edu/content/sci_papers/papers/nz-Thorne_101.pdf#page=3&view=FitV Gravitomagnetism, Jets in Quasars, and the Stanford Gyroscope Experiment] From the book "Near Zero: New Frontiers of Physics" (eds.

''"From our electrodynamical experience we can infer immediately that any rotating spherical body (e.g., the sun or the earth) will be surrounded by a radial gravitoelectric (Newtonian) field ''g''''' and a dipolar gravitomagnetic field '''''H'' . The gravitoelectric monopole moment is the body's mass M; the gravitomagnetic dipole moment is its spin angular momentum S."''Grøn, Øyvind; Hervik, Sigbjørn ?

''"In the Newtonian theory there will not be any gravitomagnetic effects; the Newtonian potential is the same irrespective of whether or not the body is rotating. Hence the gravitomagnetic field is a purely relativistic effect. The gravitoelectric field is the Newtonian part of the gravitational field, while the gravitomagnetic field is the non-Newtonian part."

(physics) The work (energy) required to move a reference particle from a reference location to a specified location in the presence of a force field, for example to bring a unit positive electric charge from an infinite distance to a specified point against an electric field.

(grammar) A verbal construction or form stating something is possible or probable.
