Discuss early views of physics as natural philosophy proposed by Aristotle. Discuss reactions to some laws proposed, which though wrong, had been believed for centuries. Use example in which Aristotle proposed, and most people believed, that a heavy object will fall at a faster rate of speed than a lighter object made of the same material. Introduce why physics is the study of the physical world dealing with matter, force, energy, motion, heat and light, and atomic structure. Discuss how the language of physics is unambiguous with no double meanings. Use as example the relationship between voltage, current and resistance when discussing electricity.
