The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton 's law of universal gravitation and in Albert Einstein 's theory of general relativity. It is also known as the universal gravitational constant, the Newtonian constant of gravitation, or the Cavendish ...
Jun 21, 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.
