The dimensions are [L^3M^(-1)T^(-2)] and the units are m^3 kg^(-1) s^(-2).
In 1789 Henry Cavendish measured G
G is called The universal gravitational constant because at any point of the universe the value of G is constant. G=6.67*10^-11 N m^2/kg^2...!!!!1
It means that the force of electrical attraction (or repulsion) between two particles with units charges will be greater than the gravitational attraction between two particles with unit mass which are the same distance apart.
It is the measure of the gravitational force experienced between any two bodies, anywhere in the universe. So, the same number is used to calculate the gravitational attraction between bodies anywhere in the universe. There are, however, some questions as to whether is is (or was) a constant over time.
The answer depends on the units used for 2.500: pounds, milligrams, tons?
Cavendish measured the gravitational constant "G".
g, the force of the Earth's gravitational attraction, is not a constant.
You can find the dimensions of derived units in the Wikipedia article on "Planck units".
There is no evidence to suggest that the gravitational constant 'G' is not the exact same number everywhere in the universe.
There are two gravitational constants. The 'real one', the Universal Gravitational Constant, is always known as G. As its name implies it works everywhere. * The other one, acceleration due to gravity, is g. It is good only on our own planet. Units of g are m s-2 . Units of G are m3 kg-1 s-2 . *Some physicists are not quite sure about this. If one starts talking to you about "Planck-length gravity" you might want to remember an urgent appointment elsewhere.
Among other things, it may refer to the gravitational constant - the constant of proportionality for the universal law of gravity. In SI units, it's magnitude is 6.67 x 10-11 m3kg-1s-2.
Force gravitational = (mass of the object)(the gravitational constant) F=mg "g" is the gravitational constant, it is equal to 9.8 m/s^2
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
An upper case (capital) G.
The attraction between two objects is: G x m1 x m2 / distance squared where m1 and m2 are the two masses involved, and G is the gravitational constant - approximately 6.674 x 10 to the power -11, in SI units.
It is m3kg-1s-2
