After being hit by an apple, I began pondering why the apple fell towards the ground naturally. I observed other objects falling and speculated on the existence of an unseen force acting on them. I eventually concluded that the force that causes objects to fall to Earth must be the same force that holds celestial bodies in their orbits. My exploration of this idea led me to develop mathematical theories that ultimately resulted in the formulation of the Universal Law of Gravitation, which states that every point mass attracts every other point mass in the universe through a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
You are Sir Isaac Newton sitting under a tree when an apple falls on your head. Can you explain what thought process led you to discover the law of gravity?
