About the Author

Chris Bruhn began his career as an aerospace engineer before figuring out that teaching physics was his calling. Since becoming an educator, he has taught all varieties of physics, in all types of high schools, and has won several educational awards. Chris is an educational trainer. He likes to create and share curriculum and educational resources as well as lead institutes and study sessions for teachers and students around the country. Chris enjoys sports, travel, painting, movie marathons with his family, and generally having fun. He likes building thingsand taking things apart to see how they work!

* Yes, were covering Newtons Third Law first!

This book is dedicated to everyone who has ever found physics mystifying and bafflingly beyond their reach. I hope this book helps you see the wonder and beauty of how the universe works.

Id like to thank all the students over the years who have taught me at least as much as I ever taught them. Thanks for learning with an open mind and heart.

Thanks to my daughter, Alina, who is taking AP Physics 1 as I write this book. She has checked my physics and given me many great reminders about how beginning physics learners view the material and what would be confusing to them.

Thanks to my son, Cole, in college as a math major, who is checking to make sure I have not made too many mistakes.

Thanks to my wife, Karen, who has made sure that I havent butchered the English language too much. And has put up with me barricaded in the office working on this book for about five months straight.

W elcome to your new physics book! Let us try to explain why we believe youve made the right choice. This probably isnt your first rodeo with either a textbook or other kind of guide to a school subject. Youve probably had your fill of books asking you to memorize lots of terms (such is school). This book isnt going to do thatalthough youre welcome to memorize anything you take an interest in. You may also have found that a lot of books jump the gun and make a lot of promises about all the things youll be able to accomplish by the time you reach the end of a given chapter. In the process, those books can make you feel as though you missed out on the building blocks that you actually need to master those goals.

With Must Know High School Physics, weve taken a different approach. When you start a new chapter, right off the bat you will immediately see one or more must know ideas. These are the essential concepts behind what you are going to study, and they will form the foundation of what you will learn throughout the chapter. With these must know ideas, you will have what you need to hold it together as you study, and they will be your guide as you make your way through each chapter.

To build on this foundation you will find easy-to-follow discussions of the topic at hand, accompanied by comprehensive examples that show you how to apply what youre learning to solving typical physics questions. Each chapter ends with review questionsmore than 300 throughout the book designed to instill confidence as you practice your new skills.

This book has other features that will help you on this physics journey of yours. It has a number of sidebars that will both help provide helpful information or just serve as a quick break from your studies. The sidebars (by the way) point out important information as well as tell you what to be careful about physics-wise. Every once in a while, an sidebar (in real life) will tell you what youre studying has to do with the real world; other IRLs may just be interesting factoids.

In addition, this book is accompanied by a flashcard app that will give you the ability to test yourself at any time. The app includes more than 100 flashcards with a review question on one side and the answer on the other. You can either work through the flashcards by themselves or use them alongside the book. To find out where to get the app and how to use it, go to the next section, The Flashcard App.
