Answer:
What is the Universal Law of Gravitation?
Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
The universal gravitation equation thus takes the form
F
∝
m

r

Universal Gravitation Equation
Newton’s conclusion about the magnitude of gravitational force is summarized symbolically as
F
=
G
m

m

r

where, F is the gravitational force between bodies, m1 and m2 are the masses of the bodies, r is the distance between the centres of two bodies, G is the universal gravitational constant.
The constant proportionality (G) in the above equation is known as the universal gravitation constant. Henry Cavendish experimentally determined the precise value of G. The value of G is found to be G = 6.673 x 10-11 N m2/kg2.
The Universal Gravitational Law can explain almost anything, right from how an apple falls from a tree to why the moon revolves around the earth. Watch the video and understand the beauty of the law of universal gravitation.
