The value of g is independent of the mass of the object and only dependent upon location - the planet the object is on and the distance from the center of that planet. Investigate! Even on the surface of the Earth, there are local variations in the value of g.

The measured value of the constant is known with some certainty to four significant digits. In SI units, its value is approximately 6.6743 × 10 −11 N⋅m 2 /kg 2. [1] The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys.
An approximate value for gravity at a distance r from the center of the Earth can be obtained by assuming that the Earth's density is spherically symmetric. The gravity depends only on the mass inside the sphere of radius r. All the contributions from outside cancel out as a consequence of the inverse-square law of gravitation. Another ...
Sep 23, 2024 · 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.

Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Sep 21, 2022 · 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...
The size of the gravitational attraction between two bodies increases in proportion with their masses, diminishes with the square of the distance between them, and has an absolute value ultimately...
