ABOUT THE AUTHORS Raymond A Serway received his doctorate at Illinois Institute of Technology and is Professor Emeritus at James Madison University In 1990 he received the Madison Scholar Award at James Madison University, where he taught for 17 years Dr Serway began his teaching career at Clarkson University, where he conducted research and taught from 1967 to 1980 He was the recipient of the Distinguished Teaching Award at Clarkson University in 1977 and of the Alumni Achievement Award from Utica College in 1985 As Guest Scientist at the IBM Research Laboratory in Zurich, Switzerland, he worked with K Alex Müller, 1987 Nobel Prize recipient Dr Serway also was a visiting scientist at Argonne National Laboratory, where he collaborated with his mentor and friend, Sam Marshall In addition to earlier editions of this textbook, Dr Serway is the coauthor of Principles of Physics, fourth edition; Physics for Scientists and Engineers, seventh edition; Essentials of College Physics; and Modern Physics, third edition He also is the coauthor of the high school textbook Physics, published by Holt, Rinehart and Winston In addition, Dr Serway has published more than 40 research papers in the field of condensed matter physics and has given more than 70 presentations at professional meetings Dr Serway and his wife, Elizabeth, enjoy traveling, golf, gardening, singing in a church choir, and spending time with their four children and eight grandchildren Chris Vuille is an associate professor of physics at Embry-Riddle Aeronautical University (ERAU), Daytona Beach, Florida, the world’s premier institution for aviation higher education He received his doctorate in physics from the University of Florida in 1989 and moved to Daytona after a year at ERAU’s Prescott, Arizona, campus Although he has taught courses at all levels, including postgraduate, his primary interest has been the delivery of introductory physics He has received several awards for teaching excellence, including the Senior Class Appreciation Award (three times) He conducts research in general relativity and quantum theory, and was a participant in the JOVE program, a special three-year NASA grant program during which he studied neutron stars His work has appeared in a number of scientific journals, and he has been a featured science writer in Analog Science Fiction/Science Fact magazine In addition to this textbook, he is coauthor of Essentials of College Physics Dr Vuille enjoys tennis, swimming, and playing classical piano, and he is a former chess champion of St Petersburg and Atlanta In his spare time he writes fiction and goes to the beach His wife, Dianne Kowing, is an optometrist for a local Veterans’ Administration clinic His daughter, Kira VuilleKowing, is a meteorology/communications double major at ERAU and a graduate of her father’s first-year physics course He has two sons, Christopher, a cellist and fisherman, and James, avid reader of Disney comics Jerry S Faughn earned his doctorate at the University of Mississippi He is Professor Emeritus and former chair of the Department of Physics and Astronomy at Eastern Kentucky University Dr Faughn has also written a microprocessor interfacing text for upper-division physics students He is coauthor of a nonmathematical physics text and a physical science text for general education students, and (with Dr Serway) the high-school textbook Physics, published by Holt, Reinhart and Winston He has taught courses ranging from the lower division to the graduate level, but his primary interest is in students just beginning to learn physics Dr Faughn has a wide variety of hobbies, among which are reading, travel, genealogy, and old-time radio His wife, Mary Ann, is an avid gardener, and he contributes to her efforts by staying out of the way His daughter, Laura, is in family practice, and his son, David, is an attorney viii PREFACE College Physics is written for a one-year course in introductory physics usually taken by students majoring in biology, the health professions, and other disciplines including environmental, earth, and social sciences, and technical fields such as architecture The mathematical techniques used in this book include algebra, geometry, and trigonometry, but not calculus This textbook, which covers the standard topics in classical physics and 20thcentury physics, is divided into six parts Part (Chapters 1–9) deals with Newtonian mechanics and the physics of fluids; Part (Chapters 10–12) is concerned with heat and thermodynamics; Part (Chapters 13 and 14) covers wave motion and sound; Part (Chapters 15–21) develops the concepts of electricity and magnetism; Part (Chapters 22–25) treats the properties of light and the field of geometric and wave optics; and Part (Chapters 26–30) provides an introduction to special relativity, quantum physics, atomic physics, and nuclear physics OBJECTIVES The main objectives of this introductory textbook are twofold: to provide the student with a clear and logical presentation of the basic concepts and principles of physics, and to strengthen an understanding of the concepts and principles through a broad range of interesting applications to the real world To meet those objectives, we have emphasized sound physical arguments and problem-solving methodology At the same time, we have attempted to motivate the student through practical examples that demonstrate the role of physics in other disciplines CHANGES TO THE EIGHTH EDITION A number of changes and improvements have been made to this edition Based on comments from users of the seventh edition and reviewers’ suggestions, a major effort was made to increase the emphasis on conceptual understanding, to add new end-of-chapter questions and problems that are informed by research, and to improve the clarity of the presentation The new pedagogical features added to this edition are based on current trends in science education The following represent the major changes in the eighth edition Questions and Problems We have substantially revised the end-of-chapter questions and problems for this edition Three new types of questions and problems have been added: ■ Multiple-Choice Questions have been introduced with several purposes in mind Some require calculations designed to facilitate students’ familiarity with the equations, the variables used, the concepts the variables represent, and the relationships between the concepts The rest are conceptual and are designed to encourage conceptual thinking Finally, many students are required to take multiple-choice tests, so some practice with that form of question is desirable Here is an example of a multiple-choice question: 12 A truck loaded with sand accelerates along a highway The driving force on the truck remains constant What happens to the acceleration of the truck as its trailer leaks sand at a constant rate through a hole in its bottom? (a) It decreases at a steady rate (b) It increases at a steady rate (c) It increases and then decreases (d) It decreases and then increases (e) It remains constant ix I.10 Index Guanine, 878 GUT See
