You can navigate through the book using the Table of Contents button. When you roll your mouse over it, you will see three links.

The Chapter TOC link takes you to the table of contents for the chapter you are currently in. You will see more sections than you might see in a typical physics textbook table of contents. We chose to make it very easy to navigate to each element of the textbook by listing sample problems, derivations and other elements discretely.

The Main TOC link takes you to the list of all the chapters in the textbook. Clicking on the third link, Physics Factbook, opens a reference tool containing useful information including mathematics review topics and formulas, unit conversion factors, fundamental physical constants, properties of the elements, astronomical data, and physics equations. The Factbook also has a built-in search feature to help you find information quickly.

This textbook has no index, but likely you will find that entering text in the “search box” is more useful. Search is located at the bottom of each Web page. Search performs its task by looking at the name of each section, at the first (or essential) time any term is defined, and at some other types of text. Typing in a phrase like “kinetic energy” will produce a number of useful results.

When you use search, you do not have to worry about sequence: You do not have to guess whether we listed something under, say, “average velocity” or “velocity average.” Search looks for the terms and presents them to you along with some of their context.

That is it for logistics. The people who worked on this textbook − about 50 of us − hope you enjoy it. We have a passion for physics, and we hope some of that carries on to you.

To explore the rest of the book, move your mouse over a Table of Contents button at the top or bottom of this page, and select the Main TOC.
