There is no evidence to suggest that the gravitational constant 'G'
is not the exact same number everywhere in the universe.
Cavendish measured the gravitational constant "G".
g, the force of the Earth's gravitational attraction, is not a constant.
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
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
An upper case (capital) G.
The gravitational constant, denoted as G, is considered to be a constant value in physics. It is a fundamental constant that is believed to remain the same over time and across the universe.
In 1789 Henry Cavendish measured G
It is m3kg-1s-2
1.
Gravitational constant was determined by lord Henry cavendish in 1798 using a torsion balance .....G=6.67 *10^-9
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
Why g is called the universal gravitational constant.Answer:Because it's the constant in Newton's Law of Universal Gravitation.It's "gravitational" because it is related to gravity; "universal ... constant" because it is the same in all cases."Universal" because it applied to the whole of the Universe.Another answer. But, g isn't called the universal gravitational constant.g is the acceleration due to gravity on our planet only.= 9.81 m s-2The universal gravitational constant is G (often called big G ) = 6.673 x 1011 m3 kg-1 s-2.It appears in Newton's equation f= Gm1m2 / d2 .
