Why is the gravitational constant a constant?

It is because of the set value of the gravitational constant that we’re able to accurate determine the mass of two orbiting objects. We can calculate the amount of force imparted on us by the Earth to keep us on the Earth – 9.81 m/s^2.

Does gravitational constant depend on the nature of medium?

The value of the gravitational constant remains the same for all astronomical systems and does not depend on the mass of the bodies or nature of the medium.

What is the value of gravitational constant G on the earth and on the moon?

The acceleration due to gravity on the surface of the Moon is about 1.625 m/s2, about 16.6\% that on Earth’s surface or 0.16 ɡ.

Does the gravitational constant depend on mass?

Perhaps the most difficult constant to measure is the gravitational constant (G). In this expression, the gravitational force depends on both the masses of the two interacting objects as well as the distance between them (the r) in the expression.

Why gravitational force does not depend on medium?

The gravitational force present between the two masses will always remain the same no matter whether the masses are in air, vacuum, water, or separated by some hindrance. Therefore, the gravitational force is not dependent on the intervening medium.

What is the value of gravitational constant G is on the earth?

The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2.

What is the value of gravitational constant G 1 on the earth and?

Gravitational constant

Values of G	Units
6.67430(15)×10−11	m3⋅kg–1⋅s–2
6.67430(15)×10−8	dyne cm2⋅g–2
4.30091(25)×10−3	pc⋅M⊙–1⋅(km/s)2

Does the value of g depends on the mass of the body?

The value of ‘g’ does not depend upon mass of the body, but gravitational pull of earth depends on mass of the body, comment. Both the statements are true. This is because g=GMR2,g does not depend upon mass (m) of the body.
