I am writing an essay on why Galileo's work was important to the development of dynamics, with particular reference to its importance to the development of Newton's Laws of Motion and the Law of Universal Gravition. I've researched some of the stuff that Galileo did: ie. rolling balls down inclined ramps, dropping objects from tall building (Law of Falling Bodies, Principle of Inertia) What else can I expand on? How should I explain what Newton did to come up with the Laws of Motion and the Law of Universal Gravitation using Galileo's ideas??
