Pedagogical Features • Greater clarity No topic, no paragraph in this book was overlooked in the search to improve the clarity of the presentation. Many changes and clarifications have been made, both small and not so small. One goal has been to eliminate phrases and sentences that may slow down the principle argument: keep to the essentials at first, give the elaborations later. • Color is used pedagogically to bring out the physics. Different types of vectors are given different colors. This book has been printed in 5 colors (5 passes through the presses) to provide better variety and definition for illustrating vectors and other concepts such as fields and rays. The photographs opening each Chapter, some of which have vectors superimposed on them, have been chosen so that the accompanying caption can be a sort of summary of the Chapter. • The wide range of Applications have been carefully chosen and integrated into the text so as not to interfere with the development of the physics, but rather to illuminate it.Some serve only as examples of physical principles, some are treated in greater depth. To make it easy to spot the Applications, a Physics Applied marginal note is placed in the margin. A list of Applications shall appear after the Table of Contents. • Problem Solving Marginal Notes are included throughout the Chapters to emphasize key Problem Solving strategies. • Problem Solving Boxes Found throughout the book, each box outlines a step-by-step approach to get students thinking about and involved in the problem at hand. • Step-by-Step Examples Following most Problem Solving Boxes, the next Example is worked step-by-step following the steps of the preceding Problem Solving Box to show students how this tool can be • Estimation Examples These help students develop skills for making order-of-magnitude estimates, even when data is scarce, or when you might never have guessed any result was possible.

Page Layout Great effort has been made to keep important derivations and arguments on facing pages. Students then don’t have to turn back and forth. [Throughout the book readers see before them, on two facing pages, an important slice of physics.] Revised Vector Notation Arrows over boldface symbols are now used to denote vectors in text and in art. Provides consistency with the way students write vectors in homework and the way professors write vectors on the board. New “Chapter Opening Questions” (COQs) These multiple-choice questions at the beginning of each Chapter immediately engage students with key Chapter concepts, presenting common student misconceptions. Students revisit the COQs later in the Chapter, as an Exercise, to see if their answers have changed. Answers to all Exercises are given at the end of the Chapter. New Chapter Contents listing on the Chapter-Opening Page Gives students an overview of Chapter topics without forcing them to turn back to the TOC. New “Approach” Steps in worked-out Examples Added to each worked-out Example, the Approach steps help students understand the reasoning behind the method used to solve the problem and answer their questions of "how/where do I start?" New “Note” Sections in worked-out Examples Added to many worked-out Examples after the Solution, these Notes sometimes remark on the solution itself, mention an application, or give an alternate approach to solving the problem. New Exercises Integrated throughout the Chapters, Exercises give students a chance to check their understanding through practice before they proceed to other topics. [Answers are given at the end of the Chapter.] New Caution marginal notes These notes in the margin of the text warn students of common mistakes / misconceptions about the topic at hand. New Computer / Numerical Problems In most Chapters, with an optional introduction in Section 2-9, these are optional and often level III Problems grouped together at the end of most Chapters. These problems require a numerical solution, often requiring a computer, spreadsheet, or programmable calculator to do the sums. New Examples and Applications New optional Example 1-9 Planck length on this smallest meaningful unit of measurement.New optional Section 2-9 Graphical Analysis and Numerical Integration, including Example 2-22 Numerical Integration, describing techniques students can use to solve problems numerically, using a computer or graphing calculator. Problems that use these numerical techniques are found at the end of many Chapters.New Example 6-10 Lagrange Point L1 explores how to determine the distance to Lagrange Point L1.Chapters 7 and 8 on Work and Energy were carefully revised including the issue of work done by friction.Chapters 10 and 11 on Rotational Motion were reorganized such that coverage of Angular Momentum is entirely in Chapter 11.Chapters 30 and 31 on Inductance and AC Circuits were combined into one Chapter.
