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.
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.
Also known as "Big G" or G, the gravitational constant was first defined by Isaac Newton in his Law of Universal Gravitation formulated in 1680. It is one of the fundamental constants of nature,...
Sir Isaac Newton's Law of Universal Gravitation helps put the laws of gravity into a mathematical formula. And the gravitational constant is the "G" in that formula.
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.
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.
What is the Gravitational Constant? The gravitational constant is the proportionality constant used in Newton’s Law of Universal Gravitation, and is commonly denoted by G. This is...
