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 andmanipulation of equations. You have, on average, 48 seconds to answereach question, and the people at ETS realize that isn’t enough time todelve into problems involving simultaneous equations or complextrigonometry. They’re more interested in testing your grasp of thebasic concepts of physics. If you’ve grasped these concepts, yourweakness 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% |
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 |
