In 1687, Sir Isaac Newton explains the force of attraction between any two objects in the universe with a formula. It is known as Newton's gravitational formula. The formula is: "Every particle in this universe attracts each other to itself, and the value of this attraction ball is proportional to the quality of the mercurial value of the particle, the proportional to the square of the distance between them, and this force acts along the straight line connector."
Let's think that 2 objects of m1 and m2 are located at each other. According to Newton's sources, two objects are attracted to each other. The m1 object is drawing the object m2 by the F2 and the m2 object by the F2 force. In fact, F1 = F2, think, F1 = F2 = F, then Newton's formula
Then, according to Newton's formula, according to the formula

The continental constant is also called universal constant. https://wikimedia.org/api/rest_v1/media/math/render/svg/d22c14ff92a490fb9fc75ed9eff432bdf2ada748 Because its value is fixed at any place in this universe and there is no change in its quality in place and time change. Its value is being
At the CGS unit, its value is,

Henry Cavendish test a test for the first G rating, although he did not count the value of G. Thus, Newton's gravitational theory was first tested in laboratory
