I extend my thanks to Grace Freedson, who was the driving force behind this books publication, and especially to Don Reis, who was not only a superb editor but also an unwavering source of support. I also appreciate Ruth Millss awesome work on the second edition and Bev Weiler and Clara Wentes careful and thorough editing of the questions and example problems for the 20102011 edition.

Thank you to Chat Hull and Jessica Broaddus, veterans of my 2002 Physics B class, who provided the idea for two free-response questions.

My 2004 students at Woodberry Forest School were extremely helpful in the development of this book. It was they who served as guinea pigs, reading chapters for clarity and correctness, making suggestions, and finding mistakes. They are Andrew Burns, Jordan Crittenden, David Fulton, Henry Holderness, Michael Ledwith, Johnny Phillips, Rob Sellers, and Chris Straka from Physics C; Wes Abcouwer, Wyatt Bone, Matt Brown, David Goodson, Bret Holbrook, Mike Johnson, Rich Lane, Jake Miller, Jake Reeder, Charles Shackelford, Beau Thomas, David Badham, Marks Brewbaker, Charlton deSaussure, Palmer Heenan, Wilson Kieffer, Brian McCormick, Eli Montague, Christian Rizzuti, Pierre Rodriguez, and Frazier Stowers from Physics B; and Andy Juc, Jamie Taliaferro, Nathan Toms, Matt Laughridge, Jamie Gardiner, Graham Gardiner, Robbie Battle, William Crosscup, Jonas Park, Billy Butler, Bryan May, Fletcher Fortune, and Stuart Coleman from the general physics class. Although Josh and I bear responsibility for all errors in the text, the folks mentioned above deserve credit for minimizing our mistakes.

The idea for the Four-Minute Drill came originally from Keen Johnson Babbage, my seventh-grade social studies teacher. Ive borrowed the idea from him for over two decades of teaching AP. Thank you!

The faculty and administration at Woodberry, in particular Jim Reid, the science department chairman, deserve mention. They have been so supportive of me professionally.

Additional thanks go to members of my 2009 AP physics classes who helped edit the practice tests: Min SuKim, Cannon Allen, Collins MacDonald, Luke Garrison, Chris Cirenza, and Landon Biggs. And to later students: Michael Bauer, Vinh Hoang, and Evan Sun.

Most important, Id like to thank Shari and Milo Cebu for putting up with me during all of my writing projects.

GREG JACOBS teaches AP Physics C, AP Physics 1, and conceptual physics at Woodberry Forest School, the nations premier boarding school for boys. He is a reader and consultant for the College Boardthis means he grades the AP Physics exams, and he runs professional development seminars for other AP teachers. Greg is president of the USAYPT, a nonprofit organization promoting physics research at the high school level. Greg was honored as an AP Teacher of the Year by the Siemens Foundation. Outside the classroom, Greg has coached baseball, football, and debate. He umpires high school baseball. He is the lead broadcaster for Woodberry football, baseball, soccer, and basketball. Greg writes a physics teaching blog available at www.jacobsphysics.blogspot.com.

I know that preparing for the Advanced Placement (AP) Physics exam can seem like a daunting task. Theres a lot of material to learn, and some of it can be rather challenging. But I also know that preparing for the AP exam is much easierand much more enjoyableif you do it with a friendly guide. So let me introduce myself; my name is Greg, and Ill be your friendly guide for this journey.
