The AP Physics 2 exam tests algebra-based physics across fluids, thermodynamics, electricity, magnetism, optics, and modern physics using multiple-choice reasoning and four distinct free-response question types. Knowing the format and what each question type demands is the fastest way to turn your content knowledge into points.
Use the topic guides below to review each question type before your exam.
AP Physics 2 covers second-year algebra-based physics. The exam does not reward memorization because you have the equation sheet the whole time. It rewards your ability to reason with physics models, translate between representations, design experiments, and connect qualitative predictions to quantitative derivations.
The exam is three hours total: Section I is 42 multiple-choice questions in 85 minutes, and Section II is 4 free-response questions in 95 minutes. Both sections are worth 50% of your score. Every FRQ has a fixed name, point value, and suggested time.
42 single-select questions (A-D) in 85 minutes. That averages 2 minutes per question, but some proportional-reasoning questions are faster and multi-step circuit or optics problems take longer. You have a calculator and the equation sheet for the full section.
Four questions in 95 minutes worth 40 points total. FRQ 1 (Mathematical Routines, 10 pts, ~20-25 min), FRQ 2 (Translation Between Representations, 12 pts, ~25-30 min), FRQ 3 (Experimental Design, 10 pts, ~25-30 min), FRQ 4 (Qualitative/Quantitative Translation, 8 pts, ~15-20 min).
Physics 2 asks you to explain systems using multiple representations: equations derived from fundamental principles, diagrams, graphs, and written justifications. The four FRQ types each isolate a different skill, so you need a specific strategy for each one, not just general physics knowledge.
Because every formula is provided, the exam focuses entirely on whether you can select the right relationship, apply it to an unfamiliar scenario, and justify your reasoning in words or diagrams. Students who treat the equation sheet as a substitute for understanding consistently lose points on derivation and justification parts.
42 questions, 85 minutes, 50% of your score. Single-select with four choices. Calculator and equation sheet provided. Covers all Physics 2 content with emphasis on proportional reasoning and conceptual application.
10 points, ~20-25 minutes. Derive symbolic expressions from fundamental principles. Show every algebraic step. Do not substitute numbers before completing the symbolic derivation.
12 points, ~25-30 minutes. The highest-value FRQ. Express one scenario as a diagram, equation, and graph, and prove all three are consistent with each other.
10 points, ~25-30 minutes. Design a procedure using listed equipment, then analyze data from a related experiment. Linearization and systematic error identification are key skills.
8 points, ~15-20 minutes. Make a conceptual prediction, derive the matching equation from a fundamental principle, then write an explicit sentence connecting the two.

The MCQ section is 42 questions in 85 minutes, worth 50% of your total score. All questions are single-select with four answer choices. You have a calculator and the official equation sheet for the entire section. Questions test proportional reasoning, conceptual understanding, and multi-step problem solving across all Physics 2 content areas.
Can you identify which physics principle applies to a scenario before reaching for the equation sheet?

FRQ 1 is worth 10 points with a suggested time of 20-25 minutes. It asks you to derive symbolic expressions starting from fundamental principles, make predictions, and use math to analyze a physical scenario. Plugging numbers in before deriving a symbolic expression is a common way to lose points.
Can you derive an expression for electric field using Gauss's law without looking at the equation sheet first?
| Aspect | Detail |
|---|---|
| Points | 10 |
| Suggested time | 20-25 minutes |
| Core skill | Symbolic derivation from first principles |
| Common error | Plugging numbers before deriving symbolically |
FRQ 2 is the highest-point question at 12 points with a suggested time of 25-30 minutes. You take one physical scenario and express it in multiple forms, such as a force diagram, a derived equation, and a graph, then demonstrate that all representations are consistent with each other.
If you draw a velocity-time graph for a charged particle in a magnetic field, can you write the matching equation and explain why the graph has that shape?
| Aspect | Detail |
|---|---|
| Points | 12 |
| Suggested time | 25-30 minutes |
| Core skill | Translating one scenario across diagrams, equations, and graphs |
| Common error | Inconsistent representations that contradict each other |
FRQ 3 is worth 10 points with a suggested time of 25-30 minutes. The question splits into two halves: a Design half where you create a procedure using listed equipment, and an Analysis half where you work with data from a related experiment. Linearization is a key skill for the analysis half.
Can you explain how internal resistance in a circuit creates a systematic error in voltage measurements and describe how to account for it?
| Aspect | Detail |
|---|---|
| Points | 10 |
| Suggested time | 25-30 minutes |
| Core skill | Experimental design and data linearization |
| Common error | Describing a procedure without specifying what to graph or how to extract the target quantity |
FRQ 4 is worth 8 points with a suggested time of roughly 15-20 minutes. The QQT asks you to do the same physics two ways: make a conceptual prediction in words, derive the matching equation from a fundamental principle, then explicitly show that your verbal reasoning and your math agree.
Can you predict the direction of the photoelectric current change when frequency increases, then derive the matching equation from the photoelectric effect relationship, and write one sentence showing they agree?
| Aspect | Detail |
|---|---|
| Points | 8 |
| Suggested time | 15-20 minutes |
| Core skill | Connecting qualitative prediction to quantitative derivation |
| Common error | Deriving the equation without writing the explicit connection back to the verbal prediction |
| Term | Definition |
|---|---|
| Systematic error | An error that consistently biases measurements in one direction, such as internal resistance causing measured voltage to be lower than the true applied voltage. Identifying and explaining systematic error is a common task in FRQ 3. |
On FRQ 1 and FRQ 4, derivation parts require a symbolic result. Plugging in numbers at the start and arriving at a numeric answer earns zero on those parts even if the number is correct. Always derive symbolically first.
Drawing a parabolic graph but writing a linear equation for the same scenario is a direct contradiction. Before moving on from FRQ 2, check that every representation you produced describes the same physical relationship.
On FRQ 3, a procedure description that lists what to measure but does not say what to graph and how to extract the target quantity from the graph is incomplete. The analysis plan is part of the design.
FRQ 4 explicitly requires you to show that your qualitative prediction and your derived equation agree. Students who derive the equation correctly but never write the connecting statement lose those points every time.
There is no penalty for wrong answers on the multiple-choice section. An unanswered question is guaranteed zero. Eliminate what you can and guess on every question you cannot confidently answer.
The proportional reasoning and principle identification you practice for MCQ is the same thinking you need to start FRQ derivations. If you can identify which law governs a scenario on MCQ, you can name the starting principle for FRQ 1 and FRQ 4.
Understanding what makes a measurement valid or biased (including systematic error) helps you evaluate answer choices on MCQ lab-based questions and write complete analysis responses on FRQ 3. These skills are not isolated to one section.
The ability to move between diagrams, graphs, and equations that TBR explicitly tests is also required in MR (showing a derived equation matches a described scenario) and QQT (connecting a verbal prediction to a derived equation). Strong TBR preparation raises your score across the entire free-response section.
Before exam day, you should be able to describe what MR, TBR, Experimental Design, and QQT each ask you to do, how many points each is worth, and roughly how much time to spend. Surprises on format cost time and confidence.
For FRQs 1 and 4, derivations must start from a named fundamental principle. Practice writing out Gauss's law, conservation of energy, Coulomb's law, and other core relationships from scratch, then deriving target expressions step by step.
When you produce a diagram, equation, and graph for the same scenario, verify they all describe the same physics. A linear graph paired with a quadratic equation is an automatic contradiction that loses points.
Identify which Physics 2 relationships are nonlinear (e.g., electric potential vs. distance, intensity vs. distance for point sources) and practice rewriting them in a form that produces a straight-line graph. Know what the slope and intercept represent.
After deriving your equation in FRQ 4, write a sentence that directly references both your verbal prediction and your equation. Do not assume the grader infers the connection. State it explicitly.
You should recognize the most common relationships on sight so you spend equation-sheet time verifying, not searching. Slow equation-sheet use on MCQ eats into your 2-minute-per-question average.
FRQ 2 is worth 12 points and FRQ 4 is worth 8. Spending equal time on both is inefficient. Roughly match your time investment to the point value of each question.
Read the topic guides for each of the four FRQ types so you understand what each question asks before you review any content. Knowing the task type changes how you study the physics.
Identify which Physics 2 topics appear most often in each FRQ type. Electricity and magnetism, optics, and modern physics are heavily represented across all four question types. Fluids and thermodynamics appear frequently in MR and TBR.
Set aside the equation sheet and practice deriving key expressions from fundamental principles. Gauss's law applications, energy conservation in circuits, and geometric optics relationships are high-frequency derivation targets.
Use the topic guides for MR, TBR, Experimental Design, and QQT to understand what earns points on each question type. Practice writing responses that explicitly address each scoring element rather than just solving the physics.
Use the AP Physics 2 score calculator to estimate where you stand based on your MCQ accuracy and FRQ performance. If your FRQ score is dragging your composite down, prioritize the highest-point question (FRQ 2 at 12 points) in your final review sessions.

AP Physics 2 FRQs for Unit 2 most often draw from fluid mechanics and thermodynamics, asking you to derive pressure or flow-rate relationships, analyze a thermodynamic cycle, or justify a claim about internal energy and work. The question types include Experimental Design, Qualitative/Quantitative Translation, and Short Answer. To practice, write out full solutions by hand, check your reasoning sentences (not just the math), and review where your logic breaks down. Past AP Physics 2 exam FRQs released by College Board are the closest thing to the real thing. You can also find topic-aligned practice at /ap-physics-2-revised/ap-physics-2-exam.
For AP Physics 2 Unit 2 practice questions, including MCQ and full practice test sets, the best starting point is /ap-physics-2-revised/ap-physics-2-exam, which has resources aligned to fluid statics, fluid dynamics, and thermodynamics. For MCQ practice, look for questions that test conceptual reasoning about pressure, buoyancy, Bernoulli's equation, and the laws of thermodynamics. College Board's AP Classroom also has unit-specific question banks and the official AP Physics 2 exam practice tests. Mixing multiple-choice drills with timed FRQ attempts gives you the most realistic prep.
Studying AP Physics 2 Unit 2 well means building a clear mental model of fluids and thermodynamics before memorizing any equations. Start with the conceptual layer: understand why pressure increases with depth, how continuity and Bernoulli's equation connect, and what the first and second laws of thermodynamics actually say. Then practice applying those ideas to AP Physics 2 FRQ-style problems where you have to explain your reasoning, not just calculate an answer. Use an ap physics 2 score calculator to track where you stand after each practice set so you know which topics need more time. A focused review at /ap-physics-2-revised/ap-physics-2-exam can help you tie the unit together before the AP Physics 2 exam.
