The law of universal gravitation states that any two objects in the universe attract each other with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
It’s a general Physics law derived from the observations by Isaac Newton. In modern language, the law states: every point mass attracts another single point mass by a force pointing along the line intersecting both the ends.
The universal gravitation force formula is given by
Where,
F = Force of attraction between two objects (N)
G = universal gravitational constant = 6.67259 x 10–11 N m2/kg2.
m1,m1 = two different masses (Kg)
r = is the distance between them
