grav·i·ta·tion

(grav'i-tā'shŭn),
The force of attraction between any two bodies in the universe, varying directly as the product of their masses and inversely as the square of the distance between their centers; expressed as F = Gm1m2l -2, where G (newtonian constant of gravitation) = 6.67259 × 10-11 m3 kg-1 s-2, m1 and m2 are the masses (in kg) of the two bodies, and l is the distance separating them in meters.
[L. gravitas, weight]

gravitation

(grăv″ĭ-tā′shŭn) [L. gravitas, weight]
The force and movement tending to draw every particle of matter together, esp. the attraction of the earth for bodies at a distance from its center.

For example, Newton's law of gravitation has already been given this form and the equations of general relativity theory and of fluid dynamics can, in principle, be expressed in this way.
Thus one gets a rather modified Newton's law of gravitation and Kepler's laws defined with this effective constant while retaining their usual forms.
Researchers failed in several searches for deviations from Newton's law of gravitation to establish the existence of a previously unknown "fifth" force (141: 14; 142: 215).
We have found that instead of considering perturbation to the Earth-Moon system, we suggest that these effect can be modeled with having an effective coupling constant (G) in the ordinary Newton's law of gravitation.
