grav·i·ta·tion·al constant

(grăv′ĭ-tā′shə-nəl)
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.

It must be pointed out that the gravitational constant G(t) is important in determining the performance of GSA and is defined as a function of time t:
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.
This means that the gravitational constant is substituted by [G.
The rate of forced height growth, after the second culmination of height increment, is determined with the gravitational constant of height structure:
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.
If the gravitational constant were infinitesimally different one way or the other, the force of gravity would be much lesser or much greater, with bad consequences for the evolution of stars and planets.
However, measurements of the most universally recognized constant, G, the gravitational constant are known to vary leading today to a relative standard uncertainty CODATA value of G that is twelve times larger than measurements of the late 1980's.
The only way to work out the problem was to discover what scientists call the gravitational constant - or The Big G.
The two most common mechanisms are a decrease in the universal gravitational constant and the creation of new matter where matter already exists.
Meanwhile G is gravitational constant, m is the mass of the earth, c is the velocity of light, r is the distance between the Geocentric and the object.
Adams simulated conditions in other universes by simultaneously varying three parameters: the gravitational constant, which determines the strength of gravity; the fine structure constant, which sets the strength of the electromagnetic force; and a number that determines the rate of nuclear reactions, which keep stars shining.
