The Law of universal gravitation is the law of universal gravitation formulated by Sir Isaac Newton in 1687 in the Philosophy of Nature math The gravitation Law explains the interaction between objects. The law is As follows: arbitrarily, two particles attract each other through a force in the direction of the Central Line. The force magnitude is proportional to the product of their Quality, and inversely proportional to their distance square, and independent of the chemical nature or physical state of the two objects and the intermediate substance, formulas are expressed: F=G*M1M2/ (R*R) (G=6.67×10^-11N·m^2/kg^2).

Newton built on the work of his predecessors (Kepler (J.Kepler), Hooke (R.Hooke), Wren (C.Yen), Halley (E.Alley)) and demonstrated with his extraordinary math ability, In 1687, the universal gravitation law was published in Principles of math, Philosophy of Nature. The discovery of universal gravitation was one of the greatest achievements of Nature scientists in the 17th century. Newton's law of gravitation

universal gravitation: F = Gm₁m₂/r²

Here

G = gravitation number = 6.6726 x 10^-11N-m²/kg²

m₁ = object 1 Quality

m₂ = object 2 Quality

r = distance between two objects
