The latest installment of the wildly successful Exploring series, this textbook supplement explains physics in remarkably clear detail. Complemented with black-and-white illustrations, the book uses ordinary speech to explain the concepts of physics. Physics equations and formulas are kept to a minimum. The author starts with the simple and goes on to the complex, and the development is somewhat historical in nature, but is intended to be an introductory book for beginning physics students. Material of a more difficult nature is found in sidebars entitled For More Study. Discussion questions are found at the end of each chapter.
