What is newton's contribution to the law of gravity?

Answer 1

Before Newton, the concept was completely non-existent.

Newton invented the whole idea, gave it the name "gravitation", created the formulas that

give it numbers, invented calculus in order to investigate how gravitation behaves, and

eventually showed ... on paper ... that the whole system he had developed predicts exactly

what we see the moon and all the planets doing in the sky.

Answer 2

Sir Isaac newton is credited with formulating the law of universal gravitation, which states that every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This law helped explain the motion of celestial bodies and laid the foundation for our understanding of gravity.
