AP Physics Summer Assignment -
Complete the math pretest. On the following page is the math pretest. This is the basic math background you need to be successful in AP Physics. These questions are the math that comes up in calculating the most common physics problems. You need to feel comfortable with this level math, and be comfortable doing it all the time. You need to score 100%.
-
Review chapter 1. You need to know the standard units of measurement in physics, dimensional analysis, significant figures, converting units!!, and trig.
-
Do Chapter 1 Problems: 1, 3, 7, 10, 15, 17, 21, 23, 39, 41, 43, 47 For help in converting units, the front cover of the text book has many common conversions. Show all work for conversions; do not just find a converting “app”.
-
Read chapter 2. Read the entire chapter to be familiar with it. - Know the difference between: - displacement and distance - velocity and speed - instantaneous velocity and average velocity - know the definition of acceleration -
Do Chapter 2 example exercises from reading in the chapter: Exercise 2.1, 2.2, 2.3, 2.4, 2.5*, 2.6, 2.7*, 2.8, 2.9, 2.10** Starred (*) problems could be considered higher in difficulty, but still important.
-
Do Chapter 2 Conceptual Questions: 1-6, 8, 9, 10, 13, 14
-
Do Chapter 2 Problems: 1, 4–7, 8a, 9, 10, 20, 21 -

Label each HW section clearly. Each one should be on its own page labeled clearly at the top. 4 pages of homework, plus the Math Pretest.
Memorize the following equations of motion. There will be a quiz the first day of class. x = position, v = velocity, a = acceleration, t = time, Δ = change in a variable - Δx = xf - xi - vf = vi + at - vaverage = Δx/Δt, - a = Δv/Δt,
Δx = vaverage ∙ t
- Δx = vit + ½ at2 - vf2 = vi2 + 2aΔx
-
Know the metric prefixes. There will be a quiz the first day of class. m mili x10-3 k kilo x103 -6 μ micro x10 M Mega x106 n nano x10-9 G Giga x109

Text Book Checkout – You will need to checkout the text book for your summer assignment. Check the school website for library available dates and times.
How to Show Work in Physics The following steps are not only the method of showing work that will help make you successful at solving physics problems, it is the only method that will earn you full credit on your homework and tests and this summer assignment. Remember there is more than one goal to homework. It is not only for you to learn and master the concepts of the course but for you to prove both that you understand it and that you did the problem correctly. Read the question thoroughly, maybe multiple times, then: 1.) Draw a picture – This allows you to summarize the question in a meaningful way (so you don't have to copy it from the book) and allows you to start thinking with your pencil. Identify the positive direction on your drawing. 2.) List the givens and identify what you are looking for. Convert values to the correct units if not already in the correct units. 3.) Write out the equation(s) you will use to solve the problem. You must write out the formula with variables. Do not just start writing numbers down. 4.) Plug in the numbers with units and solve. Yes you must include units in your work and they must be included with your answer.
The example below is what is expected of you for each and every homework or test question you complete for the course. Numbering the steps in your work is not required. Example Problem: A ball is dropped from rest from a height of 12 meters above the ground. Find the time the ball takes to hit the ground from the moment it was released.
AP Physics – Math Pretest Box all answers clearly and show all work Answers must be calculated as decimal answers Solve in terms of the other variables P = V2/R 1.) Solve for R
2.) Solve for V
Solve: 3.) 0 = 5t - 4.9t2 (hint: there are 2 answers)
4.) 3 = 10t - 4.9t2 (hint: you will need the quadratic formula)
For the right triangle shown, find the following. When L = 5 and θ = 25o 5.) Find X
Φ
L
Y θ
6.) Find Y
X When L = 8 and Y = 4.2 7.) Find θ
8.)Find Φ
When X = 4 and Y = 5 9.) Find L
10.) ___3___ = ____ 4___ x2 (10 – x)2
(Hint: 2 answers, you might end up needing the quadratic formula again)
11.) Calculate a2∙b/c where a = 2.7 x 103, b = 9.0 x 10-2, c = 3.0 x 102
12.) cos(π/4) 2π
Solve the system of equations for v and t 13.) 0 = 0.5∙v∙t - 4.9t2 50 = 0.866∙v∙t
