The Law of universal gravitation is the law of gravity that explains the interaction between objects
published by Sir Isaac Newton in 1687 in The Mathematical Principles of Natural Philosophy. The law
is as follows: any two particles are attracted to each other by forces in the direction of the heart.
The magnitude of the gravitation is proportional to their mass product and inversely proportional to
the square of their distance. It is independent of the chemical nature or physical state of the two
objects and the intermediate substance. The formula says: F=GM1M2/(RR)(G =6.67×10^-11N·m^2/kg^2).
Based on the research of his predecessors (J. Kepler, R. Hooke, C. Wyen, and E. Halley), Newton proved
with his extraordinary mathematical ability. In 1687, the law of universal gravitation was published in
The Mathematical Principles of Natural Philosophy. The discovery of the law of universal gravitation is
one of the greatest achievements of the natural sciences of the 17th century.
Newton's law of universal gravitation
Gravitational force: F = Gm1m2/r2
Here
G = gravitational constant = 6.6726 x 10-11N-m2/kg2
M1 = object 1 mass
M2 = object 2 mass
r = distance between two objects
