INTRODUCTION
Congratulations! You’ve taken a big step toward AP success by purchasing 5
Steps to a 5: 500 AP Physics B&C Questions to Know by Test Day. We are here
to help you take the next step and score high on your AP Exam so you can earn
college credits and get into the college or university of your choice.
This book gives you 500 AP-style multiple-choice questions that cover all the
most essential course material. Each question has a detailed answer explanation.
These questions will give you valuable independent practice to supplement your
regular textbook and the groundwork you are already doing in your AP
classroom. This and the other books in this series were written by expert AP
teachers who know your exam inside out and can identify the crucial exam
information as well as questions that are most likely to appear on the exam.
You might be the kind of student who takes several AP courses and needs to
study extra questions a few weeks before the exam for a final review. Or you
might be the kind of student who puts off preparing until the last weeks before
the exam. No matter what your preparation style is, you will surely benefit from
reviewing these 500 questions, which closely parallel the content, format, and
degree of difficulty of the questions on the actual AP exam. These questions and
their answer explanations are the ideal last-minute study tool for those final few
weeks before the test.
Remember the old saying, “Practice makes perfect.” If you practice with all
the questions and answers in this book, we are certain you will build the skills
and confidence needed to do great on the exam. Good luck!

Chapter 1
Vectors
1. Add the following vectors and give the resultant vector: (5î+9ĵ), (6î-3ĵ),
(2î-12ĵ).
(A) 31
(B) 14, 3, −10
(C) (13î-6ĵ) (D) (13î+24ĵ) (E) (14î+3ĵ-10ç) 2. Why are North, South, East,
and West not vectors?
(A) They are vectors.
(B) They state a direction.
(C) They state a direction but not a magnitude.
(D) They are scalars.
(E) They have no reference coordinates.
3. A temperature is a scalar because (A) it is a vector.
(B) it measures heat.
(C) it only has one dimension and two directions.
(D) it states a magnitude but not a direction.
(E) it is a qualitative measure.
4. What is the difference between velocity and speed?
(A) There is no difference.
(B) Velocity is a vector, and speed is a scalar.
(C) Speed is a vector, and velocity is a scalar.
(D) Speed states only a magnitude, and velocity states a magnitude and
direction.
(E) Velocity states only a magnitude, and speed states a magnitude and
direction.
5. Why can a vector be expressed in an R Φ system?
(A) It cannot be expressed in an R θ Φ system.
(B) It cannot be expressed because it has no x, y, z directions.
(C) It can be expressed because a magnitude is expressed by R and a direction
by θ and Φ.
(D) It can be expressed because R θ Φ can be expressed as x, y, z components.
(E) It cannot be expressed because R θ Φ is only used in special cases.

(A) 9°
(B) 80°
(C) 9.46°
(D) 80.5°
(E) .167 radians
8. What is the dot product of two vectors, A and B?
(A) |A|·|B|
(B) |A|·|B|·sinθ
(C) |A|·|B|·cosθ
(D) |A|·|B|·tan|·sinθ
(E) |A|·|B|arctan|·sinθ
9. What is the cross product of two vectors, A and B?
