... Perhaps, the best place to start then would be with such a simple item as an apple (after all it is what "sparked" Newtons creativity). The apple is one of the two curiosities (the other being the moon) that led Newton to discover The Law of Universal Gravitation in 1666 (Eddington 93). ... Newtons Third Law of Motion says that every force exerted by
one object on another is equal to a force, but opposite in direction, exerted be the second object on the first (every reaction has an equal but opposite reaction). ... When the time Newton came around he mathematically proved that, if Keplers First Law was true, then the force on a planet varied inversely with the square of the distance between the planet and the sun. He did this using Keplers Third Law (Zitzewitz 160). ...
Newton, confident that his idea of all objects exerting a force back on
Earth, devised a formula for Universal Gravitation. It is important to note that Newton was not the first to think of Universal Gravitation, he was just the first one to make considerable and remarkable proofs for it based on mathematical explanations. ... Also, as he had proved earlier using Keplers Third Law of Motion, that the force between two objects is inversely proportional to their distances squared (an inverse square law), then that must also be part of the Universal Gravitation equation.
