The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).
The constant of proportionality, G, in this non-relativistic formulation is the gravitational constant. Colloquially, the gravitational constant is also called "Big G", distinct from "small g" (g), which is the local gravitational field of Earth (also referred to as free-fall acceleration).
The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. Also known as "Big G" or G, the gravitational ...
GME, the gravitational parameter for the Earth as the central body, is called the geocentric gravitational constant. It equals (3.986 004 418 ± 0.000 000 008) × 1014 m3⋅s−2. [3]
The standard acceleration of gravity for Earth is defined (CODATA 2018) as 9.80665 m/s 2 (exact).
Gravitational constant, physical constant denoted by G and used in calculating the gravitational attraction between two objects, which is equal to G times the product of the masses of the two objects divided by the square of the distance between them. The value of G is 6.6743 x 10^-11 m^3 kg^-1 s^-2.
If a person has a mass of 60.0 kg, what would be the force of gravitational attraction on him at Earth’s surface? G is given above, Earth’s mass M is 5.97 × 10 24 kg, and the radius r of Earth is 6.38 × 10 6 m. Putting these values into Newton’s universal law of gravitation gives
