This is a nonmathematical physics
textbook, designed so that it can be used either for a semester-length course of the type popularized by Hewitt, or for a shorter course of 8 or 10 weeks. The book
covers conservation of mass and energy
, conservation of momentum, conservation of angular momentum, relativity, electricity, fields, the ray model of light and waves.
The book is designed so that chapters 1, 2, and 5 are the only ones that are required for continuity; any of the others can be included or omitted at the instructor’s discretion, with the only constraint being that chapter 6 requires chapter 4.
