6. © Houghton Mifflin Harcourt Publishing Company Chapter 1 Physics The goal of physics is to use a small number of basic concepts, equations, and assumptions to describe the physical world. These physics principles can then be used to make predictions about a broad range of phenomena. Physics discoveries often turn out to have unexpected practical applications, and advances in technology can in turn lead to new physics discoveries. Section 1 What Is Physics?
