GENERAL KNOWLEDGE

Detailed explanation-1: -Newton’s Law of Universal Gravitation.

Detailed explanation-2: -Isaac Newton is best know for his theory about the law of gravity, but his “Principia Mathematica” (1686) with its three laws of motion greatly influenced the Enlightenment in Europe.

Detailed explanation-3: -In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Detailed explanation-4: -Eventually Newton’s genius came to be widely known. His three laws of motion–inertia, acceleration, and action and reaction–remain a cornerstone of modern physics. His law of universal gravitation laid forth the theory that all particles in the universe exerted some gravitational force.
