Physics for Scientists and Engineers (with PhysicsNOW and InfoTrac) Raymond A Serway - Emeritus, James Madison University John W Jewett - California State Polytechnic University, Pomona ISBN 0534408427 1296 pages Case Bound 1/2 x 10 7/8 Thomson Brooks/Cole © 2004; 6th Edition This best-selling, calculus-based text is recognized for its carefully crafted, logical presentation of the basic concepts and principles of physics PHYSICS FOR SCIENTISTS AND ENGINEERS, Sixth Edition, maintains the Serway traditions of concise writing for the students, carefully thought-out problem sets and worked examples, and evolving educational pedagogy This edition introduces a new co-author, Dr John Jewett, at Cal Poly – Pomona, known best for his teaching awards and his role in the recently published PRINCIPLES OF PHYSICS, Third Edition, also written with Ray Serway Providing students with the tools they need to succeed in introductory physics, the Sixth Edition of this authoritative text features unparalleled media integration and a newly enhanced supplemental package for instructors and students! Features A GENERAL PROBLEM-SOLVING STRATEGY is outlined early in the text This strategy provides a series of steps similar to those taken by professional physicists in solving problems This problem solving strategy is integrated into the Coached Problems (within PhysicsNow) to reinforce this key skill A large number of authoritative and highly realistic WORKED EXAMPLES promote interactivity and reinforce student understanding of problem-solving techniques In many cases, these examples serve as models for solving end-of-chapter problems The examples are set off from the text for ease of location and are given titles to describe their content Many examples include specific references to the GENERAL PROBLEM-SOLVING STRATEGY to illustrate the underlying concepts and methodology used in arriving at a correct solution This will help students understand the logic behind the solution and the advantage of using a particular approach to solve the problem About one-third of the WORKED EXAMPLES include new WHAT IF? extensions CONCEPTUAL EXAMPLES include detailed reasoning statements to help students learn how to think through physical situations A concerted effort was made to place more emphasis on critical thinking and teaching physical concepts in this new edition Both PROBLEM-SOLVING STRATEGIES and HINTS help students approach homework assignments with greater confidence General strategies and suggestions are included for solving the types of problems featured in the worked examples, end-of-chapter problems, and PhysicsNow This feature helps students identify the essential steps in solving problems and increases their skills as problem solvers END-OF-CHAPTER PROBLEMS – An extensive set of problems is included at the end of each chapter Answers to odd-numbered problems are given at the end of the book For the convenience of both the student and instructor, about two thirds of the problems are keyed to specific sections of the chapter All problems have been carefully worded and have been checked for clarity and accuracy Solutions to approximately 20 percent of the end-of-chapter problems are included in the Student Solutions Manual and Study Guide These problems are identified with a box around the problem number Serway and Jewett have a clear, relaxed writing style in which they carefully define new terms and avoid jargon whenever possible The presentation is accurate and precise The International System of units (SI) is used throughout the book The U.S customary system of units is used only to a limited extent in the problem sets of the

Answers to Odd-Numbered Problems Index A.1 A.1 A.14 A.30 A.32 A.33 A.37 I.1 Mechanics PA R T hysics, the most fundamental physical science, is concerned with the basic principles of the Universe It is the foundation upon which the other sciences— astronomy, biology, chemistry, and geology—are based The beauty of physics lies in the simplicity of the fundamental physical theories and in the manner in which just a small number of fundamental concepts, equations, and assumptions can alter and expand our view of the world around us The study of physics can be divided into six main areas: P classical mechanics, which is concerned with the motion of objects that are large relative to atoms and move at speeds much slower than the speed of light; relativity, which is a theory describing objects moving at any speed, even speeds approaching the speed of light; thermodynamics, which deals with heat, work, temperature, and the statistical behavior of systems with large numbers of particles; electromagnetism, which is concerned with electricity, magnetism, and electromagnetic fields; optics, which is the study of the behavior of light and its interaction with materials; quantum mechanics, a collection of theories connecting the behavior of matter at the submicroscopic level to macroscopic observations The disciplines of mechanics and electromagnetism are basic to all other branches of classical physics (developed before 1900) and modern physics (c 1900–present) The first part of this textbook deals with classical mechanics, sometimes referred to as Newtonian mechanics or simply mechanics This is an appropriate place to begin an introductory text because many of the basic principles used to understand mechanical systems can later be used to describe such natural phenomena as waves and the transfer of energy by heat Furthermore, the laws of conservation of energy and momentum introduced in mechanics retain their importance in the fundamental theories of other areas of physics Today, classical mechanics is of vital importance to students from all disciplines It is highly successful in describing the motions of different objects, such as planets, rockets, and baseballs In the first part of the text, we shall describe the laws of classical mechanics and examine a wide range of phenomena that can be understood with these fundamental ideas ■ ᭣ Liftoff of the space shuttle Columbia The tragic accident of February 1, 2003 that took the lives of all seven astronauts aboard happened just before Volume of this book went to press The launch and operation of a space shuttle involves many fundamental principles of classical mechanics, thermodynamics, and electromagnetism We study the principles of classical mechanics in Part of this text, and apply these
