grav·i·ta·tion·al constant

n. Abbr. G
The constant in Newton's law of gravitation that yields the attractive force between two bodies when multiplied by the product of the masses of the two bodies and divided by the square of the distance between them. Also called newtonian constant of gravitation.

Gravitational Constant. The gravitational constant G(t) is a function of the initial value ([G.sub.0]) and decreases as time passes.
At this point, it should be noted that, even though G is referred to as the "gravitational constant", it will no more be a constant as seen in (8) under these assumptions.
Setting [W.sub.2] = 1 and [W.sub.i'] = 1 in variational principle Eq.(15), and other weighted constants are all equal to 0, namely applying Eq.(7) and Eq.(13) to derive the changing rule for the gravitational coefficient G' (instead of the gravitational constant G) and make the gravitational formula in accordance with the inverse square law.
The Planck time is also calculated from the gravitational constant, the speed of light and Planck's constant in such a way that moving at one Planck length per one Planck time would be equal to the speed of light.
G stands for the universal gravitational constant ([m.sup.3] x [kg.sup.-1] x [s.sup.-2]), [rho] is the 3-D mass density function (kg x [m.sup.-3]).
where r is the scalar curvature at any point of the space time and K is the gravitational constant [6].
Nor is the gravitational constant G changing measurably.
In the Einstein's field equations the Gravitational constant G has been introduced via the Newtonian approximation of the Einstein field equation.
The rate of forced height growth, after the second culmination of height increment, is determined with the gravitational constant of height structure:
where G is the Newtonian gravitational constant. The value for g at the earth's surface is [g.sub.s] = G[M.sub.e]/[R.sub.e.sup.2].
I guess the next thing is for the politicians to pass a law requiring more BTU's per gallon of gasoline or a decrease in the gravitational constant.
