Newton's law of universal gravitation says 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.
The Gaussian gravitational constant (symbol k) is a parameter used in the orbital mechanics of the Solar System . It relates the orbital period to the orbit's semi-major axis and the mass of the orbiting body in Solar masses .
Feb 26, 2024 · In Newton’s law of universal gravitation, the attractive force between two objects ( F) is equal to G times the product of their masses ( m1m2) divided by the square of the distance between them ( r2 ); that is, F = Gm1m2 / r2. The value of G is (6.6743 ± 0.00015) × 10 −11 m 3 kg −1 s −2.

Aug 11, 2021 · The constant G is called the universal gravitational constant and Cavendish determined it to be G = 6.67 x 10 −11 N • m 2 /kg 2. The word ‘universal’ indicates that scientists think that this constant applies to masses of any composition and that it is the same throughout the Universe.
