What Is Isaac Newton’s Theory of Gravity?

Isaac Newton’s theory of gravity states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The law is represented as: F=G (m1m2)/R.

The level of proportionality is enhanced by G, the gravitational constant. Its value is: 6.672X10-11 N-m2/Kg2. The particle with lesser mass accelerates more towards the other, though the magnitude of the force acting on both the particles is the same. An increase in the distance between the objects also reduces the force of gravity between them. The gravity effects on such a far away object are considerable only when they are massive.
