Document Summary
Physics is the study of the fundamental laws of nature. Physics is the activity of trying to find the rules by which nature plays. How is this possible: physics is not a mess of separate equations to be memorized. Learn the basic laws, fundamental relationships, and the skill in applying them. Introduction: keep in mind that physics is not really about finding an appropriate equation and plugging in numbers, but is instead about understanding concepts. Through observation, developing a good model with predictive ability, and measurement. Observation: is essential for figuring out a law or a rule things follow. The cornerstone of discovering natural laws: should be quantitative, having numerical value. Based on our observations we make models. A model is a mental image of objects or phenomena that we experience directly. By modeling, a complex object or problem is simplified: by excluding all but the important part.
