The best way to do well on SAT II Physics is to be really good at physics. For that, there is no substitute. But the physics whiz who spends the week before SAT II Physics cramming on Lagrangian mechanics and Dirac notation probably won’t fare any better than the average student who reviews this book carefully. Why? Because SAT II Physics Tests (and first-year university courses) do not cover Lagrangian mechanics or Dirac notation. Take this moment to sigh with relief.
This chapter will tell you precisely what SAT II Physics will test you on, how the test breaks down, and what format the questions will take. You should read this information carefully and base your study plan around it. There’s no use spending hours on end studying for stuff that’s not relevant to the test. Knowing nothing about electromagnetic induction will hurt you on the test, but nowhere near as much as knowing nothing about optics will.
Content of SAT II Physics
Math and physics go hand in hand, right? You might be surprised, then, to learn that you aren’t allowed to use a calculator on SAT II Physics. The math required of you never goes beyond simple arithmetic and manipulation of equations. You have, on average, 48 seconds to answer each question, and the people at ETS realize that isn’t enough time to delve into problems involving simultaneous equations or complex trigonometry. They’re more interested in testing your grasp of the basic concepts of physics. If you’ve grasped these concepts, your weakness in math isn’t going to hurt you.
ETS breaks down the concepts you need to know for the test into six categories:
| Topic | Percentage of the Test |
|---|---|
| Mechanics | 34–38% |
| Electricity and Magnetism | 22–26% |
| Waves | 15–19% |
| Heat, Kinetic Theory, and Thermodynamics | 8–12% |
| Modern Physics | 8–12% |
| Miscellaneous | 2–4% |
While these categories are helpful, they are also very broad. You may be a whiz with waves but a loser with lenses, and want to know how much of the waves portion of the test will be devoted to optics. To help you out, we’ve broken the test down even further so that you’ll know exactly where to expect to feel the squeeze. (These figures are only approximations, and may vary from test to test.)
| Topic | % of the Test | Number of Questions |
|---|---|---|
| Mechanics | 34–38% | 25–29 |
| Vectors | 2% | 1–2 |
| Kinematics | 6% | 4–5 |
| Dynamics | 10% | 7–8 |
| Work, Energy, and Power | 6% | 4–5 |
| Special Problems in Mechanics | 5% | 3–4 |
| Linear Momentum | 2% | 1–2 |
| Rotational Motion | 1% | 0–1 |
| Circular Motion and Gravitation | 4% | 2–4 |
| Thermal Physics | 8–12% | 6–10 |
| Heat and Temperature | 4% | 2–4 |
| Kinetic Theory and Ideal Gas Laws | 2–3% | 1–2 |
| Laws of Thermodynamics | 1% | 0–2 |
| Heat Engines | 2–3% | 1–2 |
| Electricity & Magnetism | 22–26% | 16–20 |
| Electric Fields, Forces, Potential | 10% | 7–8 |
| Magnetic Fields and Forces | 6% | 4–5 |
| Electromagnetic Induction | 1% | 1 |
| Circuits and Circuit Elements | 6% | 4–5 |
| Waves | 15–19% | 11–15 |
| Waves | 10% | 7–8 |
| Optics | 7% | 5–6 |
| Modern Physics | 8–12% | 6–9 |
| Special Relativity | 1–2% | 1–2 |
| Atomic Models | 3% | 2–3 |
| Quantum Physics | 2% | 1–2 |
| Nuclear Physics | 3% | 2–3 |
| Miscellaneous | 2–4% | 1–3 |
| Graph Analysis | 1–2% | 0–2 |
| Equation Manipulation | 0.5–1% | 0–1 |
| Significant Digits and Lab Skills | 0.5–1% | 0–1 |
The chapters of this book are organized according to these categories. If a physics topic is not in this book, you don’t need to know it. Here’s some other helpful information:
You need to know: the formulas expressing physical relationships (such as F = ma), how to manipulate equations, how to read a graph
You don’t need to know: trig identities, calculus, three-dimensional vectors and graphs, physical constants (such as G = 6.67
10–11 N·m2 ⁄ kg2)
10–11 N·m2 ⁄ kg2)
