Since its first printing in 1947, College Physics has conveyed the beauty and breadth of physics. This new edition represents the most comprehensive revision in the long, successful history of the book. It perpetuates those qualities and features that users of previous editions have found so desirable: comprehensive subject coverage, meticulous accuracy, complete explanations, extensive examples. The seventh edition uses a more relaxed and informal prose style making it more "user-friendly." The end-of-chapter problems have been extensively revised and grouped in three categories by difficulty. Problem-Solving Strategy sections list specific suggestions for developing a methodical and systematic approach to solving problems. Each chapter now begins with an introductory paragraph that summarizes the content of the chapter and relates it to what has gone before and what will come later. This encourages readers to look both backward and forward in order to see clearly the interrelations of various areas of physics and the beauty and fundamental unity of the subject. The goal of this text is to provide a broad, rigorous introduction to physics at the beginning college level. The primary emphasis is on physical principles and the development of problem-solving ability, rather than on historical background or specialized applications. - from Amzon
