ACKNOWLEDGMENTS
I extend my thanks to Grace Freedson, who was the driving force behind this book’s publication, and
especially to Don Reis, who was not only a superb editor but also an unwavering source of support. I also
appreciate Ruth Mills’s awesome work on the second edition and Bev Weiler and Clara Wente’s careful
and thorough editing of the questions and example problems for the 2010–2011 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. I’ve borrowed the idea from him for 16 years 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
2013 physics team members Michael Bauer and Vinh Hoang.
Most important, I’d like to thank Shari and Milo Cebu for putting up with me during all of my writing
projects.
