## 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.

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. This effective coupling takes care of the perturbations that arise from the effect of other gravitational objects.
Applying Newton's law of gravitation, the scientists then estimate the amount of mass that must be present to account for such rapid motion.
The Newton's law of gravitation is arrived if we introduce an assumption that C and the masses of particles are changing so slowly that they can be treated as constants.
