What is the value of g being used as a constant and why is this value used?

The value of g depends on latitude because the Earth is wider at the equator than at the poles.
g = 9.80612 - 0.025865 cos (2 x latitude) metres/sec/sec
It expresses how quickly an object accelerates after being dropped.
The formula gives 9.7802 at the equator and 9.8320 at the poles.
The weight of a 1 kg mass is g Newtons.

Does the value of a g and G vary.how?
The value of universal gravitational Constant(G) doesn't change it is constant at any place in the universe, it's value is 6.67259 x 10-11Nm2/Kg2 But the value of g varies from from place to place on earth,planet to planet and star to star because g=GM/R2 As G is constant g depends on M=mass of planet,R=radius of planet,so g varies with the change in M and R.

What is the value of g in space?
G usually stands for the gravitational constant, wich is rounded to 9.8 for the whole surface of the earth. The second decimal is used for cases that need greater accuracy and is dependant on the location you are at. For example, Scandinavia uses 9.82 as the gravitational constant.
What is G in physics and what is the value of G?
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.
What happens to the acceleration of a body as it falls freely?
The free fall acceleration of the earth is approximately related to the distance from the surface by the following formula. g = GM/(R2 + h) where G = universal gravitational constant, M = Mass of Earth, R = Radius of Earth, h = distance from the surface of the earth g = 3.98 * 1014 / ( (6.0 * 106 )2+ h) as h increases to a very low value near the surface of the earth the value of g can be approximately taken to be constant near the surface of the earth. So the acceleration is constant near the surface of the earth.
Value of g in universe?
I think that g (the gravitational constant) varies dependent on your proximity to other massive bodies. For example the value of g on the moon is less than the value of g on earth. It is not constant throughout the universe.
What is the value of 'G' on earth and on moon?
The average equatorial surface gravity on Earth is 0.99732 g On the moon it is 0.1654 g The numerical constant G that is used in Newton's Law of Universal Gravitation is a constant no matter where you are. (6.67 X 10-11).

Why G is called universal constant?
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
Value of gravitational constant on earth and moon?
It's the same as that of Earth but the value of g varies from one object to the other. The value of the gravitational constant or the BIG "G" remains constant. I think you confused it with the LITTLE "g" which is the gravitation of a object (one with mass) or the acceleration due to gravity. The value of g on Earth and Moon is 9.8m/s^2 and 1.6249m/s^2, respectively. I hope this answers you all.
What is non numeric constant?
An algebraic letter. e/g 5a 'a' is a non numeric constant. Remember in algebraic , when a letter is given , it means that the value of the letter is a constant, but the value is unknown .

Proof of universal gravitional law where did come from ' G' value?
What is g equals rz for r?
In the equation g = rz, r represents a variable or a constant value. The specific value of r would need to be provided in order to determine its numerical value in the equation.
Who calculate the value of universal gas constant 'G'?
The universal gas constant is denoted by R = 8.314 J/kgK, (but not G which denotes the Gibbs free energy of a given reaction at given conditions.
Why is it necessary to use the universal gravitation constant in the universal law of gravitation?
To rationalize the units on both sides of the equation, E= -GmM/r, e.g if feet is used as the unit of distance r then the Constant G would have a different value.
