    ❮ ix BIBLIOGRAPHY PREFACE How is this book different from all other AP Physics prep books? The quality of the prep book starts with the author. Greg Jacobs has taught all versions of AP (and non-AP) physics since 1996. His hundreds of students over the years have a greater than 99 percent pass rate; more than 70 percent earn 5s. Greg has graded the exams, he has written questions that have appeared on exams, and he has taught teach- ers how to teach to the exams. The leading blog about physics teaching is his—“Jacobs Physics.” (Take a look at it.) Greg knows what he’s talking about, and the proof is in the results and feedback from his students. AP Physics 1 emphasizes conceptual understanding over algebraic manipulation, and so does this book. So many people presume that physics is about finding the right numbers to plug into the right equation. That couldn’t be further from the truth. Successful physics students can explain why they chose a specific equation. They can explain what values for each variable are reasonable, and why. They can explain the physical meaning of any mathematical manipulation—how would this problem look in the laboratory? What equipment would be used to measure these values? The AP Physics 1 Exam mostly asks questions that are not about number crunching. Greg has been teaching “beyond the numbers” for years, and he brings his expertise in explaining complex concepts in simple language. Your textbook is impenetrable, even to senior physics majors. This prep book is readable. Be honest—when you read your textbook, you really just try the problems at the end of the chapter, then look back for a template of how to do those problems. Well, this book’s content review is structured around this very method. Greg poses example questions and talks you through them. On the way, he shows you the relevant facts and equations, as well as how you are supposed to know they are relevant . He explains not just the answer, but the thought process behind the answer. You do not have to be already good at physics to understand the text. This book’s practice tests and practice questions are authentic. One of the primary tenets of Greg’s physics teaching is that in-class tests should look exactly like the real AP exams. The College Board has published a curriculum guide that provides express guidance as to the style and content of the exam questions. Greg’s practice tests are derived directly from what the curriculum guide says. He has vast experience phrasing questions in the style seen on College Board exams. Every practice question includes not just an answer, but also a thorough expla- nation of how to get that answer. The back of your textbook may provide answers like “2 m/s” or “increase.” Huh? Skim through and look at the solutions to the practice exam, and to the end-of-chapter questions. They’re complete. This book’s solutions explain everything, even sometimes the common mistakes that you might have made by accident. Exam readers expect thoroughness on the free-response problems—you should expect the same from your prep book. It is not possible to prepare well for AP Physics merely by using recycled mate- rial from previous AP or honors physics courses. Even after eight years of AP Physics 1, the majority of teachers—and every AP prep book bar this one—keep using the same problems and presentations, just tweaking the covered topics to match the new exam.

    x ❯ Preface And students in those classes, students who use those prep books, have a comeuppance on exam day. The AP Physics 1 Exam asks for explanations, not calculations; it does not give pity points for writing relevant equations. And in eight years there have been only two—TWO—problems requiring numerical answers in the free-response section. AP Physics 1 demands a revolutionarily different approach to learning physics. Your parents’ generation might kvetch about cell phones and the Internet, but if they’re still doing busi- ness by landline and U.S. mail, well, they’re lucky to be doing business at all. Ditto for your teacher who moans about the good old days when physics was taught with calculation after calculation.

    ❮ xi The original idea for this book came many moons ago, when my AP students in 1999 couldn’t stand the other review books on the market. “We can write a better book than that,” they said. And we did. Justin Kreindel, Zack Menegakis, Adam Ohren (who still owes me four sandwiches from Mississippi Sweets for poking Jason during class), Jason Sheikh, and Joe Thistle were the cast members for that particular opera. Josh Schulman , also a member of that 1999 class, was the one who buckled down and put pen to paper, or rather fingers to computer keys. His first draft of a book forced me to revise and finish and publish. Del Franz has been a fabulous editor for this and other projects. I appreciate his toils. The faculty and administration at Woodberry Forest School, in particular former sci- ence department chairman Jim Reid , deserve mention. They have been extraordinarily supportive of me professionally. Two amazing physics teachers have vetted this new book for the new exam. They have done tremendous work in exchange for nothing but a free cup of coffee. Thank you, Jeff Steele (who gave feedback on the practice tests) and Matt Sckalor (who read every content chapter). I owe you both. Thank you to those who sent in errata from the first edition. I’m particularly indebted to Glenn Mangold and Drew Austen, who sent in three pages’ worth of edits, along with careful and thorough justifications for each—wow. Joseph Rao, Patrick Diehl, Mike Pozuc, Shannon Copeland, Frank Noschese, Hugh Ross, Ron Qian, and I’m sure others I’ve missed have also sent in corrections or thoughts that I’ve used. And to all of the Jacobs Physics blog readers, know that I deeply appreciate the comments, e-mails, and conversa- tions you send my way. Most important, thank you to Shari and Milo for putting up with me during all of my writing projects. —Greg Jacobs ACKNOWLEDGMENTS
