Formula: F=G*M 1M2/(R*R).
(g=6.67× 10^- 1 1n？ m^2/kg^2)。
The attraction between two objects.
G: constant of universal gravitation
M 1: the mass of the object 1.
M2: mass of object 2
R: the distance between two objects
According to the international system of units, the unit of f is Newton (n), the unit of m 1 and m2 is kilogram (kg), and the unit of r is meter (m). The constant g is approximately equal to 6.67×10-11power nm2-2 (cow
law of universal gravitation
It was published by Newton in Mathematical Principles of Natural Philosophy in 1687 on the basis of previous studies. Newton declared that any two objects in nature are attracted to each other, and the magnitude of gravity is directly proportional to the product of the mass of the two objects and inversely proportional to the square of the distance between the two objects.
