AP Physics 1 Free Response QuestionsFRQ Archive and Practice (2019 to 2025)

What do AP Physics 1 FRQs test?

Constructing and justifying physics arguments, not substituting numbers into memorized formulas.

The free response section accounts for half the AP Physics 1 score, and it is the half that most sharply separates students who understand physics from students who have memorized it. The five questions test whether you can design an experiment from scratch, derive a relationship algebraically, predict how a system changes when one variable is modified, and write a coherent paragraph explaining a physical phenomenon without leaning on equations as a substitute for reasoning. The 2024 AP Physics 1 Course and Exam Description published by College Board specifies that the FRQ section assesses all seven Science Practices: modeling, mathematical routines, scientific questioning, experimental methods, data analysis, argumentation, and making connections. A student who approaches the section looking for the right formula to plug into will underperform against a student who can narrate what the physics requires and why.

What are the five AP Physics 1 FRQ types?

AP Physics 1 has three structurally distinct FRQ types, not a simple long versus short split.

The five free response questions on AP Physics 1 divide into three types that each demand a different approach. Understanding the type before you write determines which skills to activate. The structure has been consistent since the 2021 CED update: one Experimental Design question (15 points), one Quantitative Qualitative Translation question (12 points), and three Short Answer questions worth 7 points each, one of which is a Paragraph Length Response.

How are AP Physics 1 FRQs scored?

Analytic point rubrics scored by trained Readers, with every part graded independently.

Each of the five FRQ questions has a College Board scoring guideline that lists the exact requirements for each point. Readers award a point only when a response meets that point's stated requirement. There is no holistic grade and no penalty for an incorrect attempt, so every part of every question is worth attempting. Partial credit is the norm: a student who earns 6 of 15 points on the Experimental Design question and 8 of 12 on the Quantitative Qualitative Translation has banked 14 points before reaching the Short Answer questions. The Experimental Design question is the highest point value question on the exam at 15 points, making it the single most important question for raw score. According to College Board's scoring guidelines, the Paragraph Length Response awards points specifically for the quality and coherence of the argument rather than for the presence of correct equations, which means a well reasoned prose explanation outperforms a list of formulas even when both contain the correct physics. The year by year scoring guidelines and how the FRQ raw total converts to the composite 1 to 5 score are on the AP Physics 1 scoring guidelines page.

Worked example: how a real AP Physics 1 FRQ was scored

2023 Quantitative Qualitative Translation (Q2), gravitational force and orbital period. A low mean score question that illustrates why showing algebraic steps is not optional.

The 2023 AP Physics 1 Question 2 is a Quantitative Qualitative Translation question on Newton's Law of Universal Gravitation and orbital mechanics. Students were asked to derive an expression for a satellite's orbital period for given quantities and then predict qualitatively how the period changes when the orbital radius is doubled. This question type is distinctive to AP Physics 1 and is one of the most common sources of lost points on the exam. The parts below pair the rubric requirement from the 2023 AP Physics 1 Scoring Guidelines with a response that earns the point and one that does not.

1. Part (a): Derive an algebraic expression for the orbital period T for the orbital radius r, the planet mass M, and fundamental constants.

   Rubric: Point earned only if the response shows the derivation starting from Newton's second law or universal gravitation, equates gravitational force to centripetal force (F = mv squared over r, F = GMm over r squared), algebraically solves for velocity, then substitutes into the circumference divided by speed relationship to obtain T. An unsupported final expression earns zero points on the derivation.

   Earns the point: Setting gravitational force equal to centripetal force: GMm divided by r squared equals mv squared divided by r. Solving for v: v equals the square root of GM over r. Substituting into T equals 2 pi r divided by v gives T equals 2 pi r to the three halves divided by the square root of GM. All steps shown.

   Loses the point: T equals 2 pi times the square root of r cubed over GM. (Correct final expression, but no algebraic steps shown. The derivation points require each step of the manipulation to be visible. The rubric cannot award points for an unsupported answer, regardless of whether the answer is correct.)

2. Part (b): Using your derived expression, predict qualitatively whether the orbital period increases, decreases, or stays the same when the orbital radius is doubled. Justify your prediction.

   Rubric: Point earned only if the response explicitly identifies that T is proportional to r to the three halves power from the derived expression, notes that doubling r multiplies r to the three halves by 2 to the three halves (approximately 2.83), and concludes that the period increases. A response that only says the period increases without the ratio reasoning from the derived expression does not earn the point.

   Earns the point: From the derived expression T is proportional to r to the three halves. Doubling r replaces r with 2r, so T scales by (2r) to the three halves divided by r to the three halves, which equals 2 to the three halves, approximately 2.83. The period increases by a factor of approximately 2.83.

   Loses the point: If r doubles, T also increases because a larger orbit takes longer to complete. (The conclusion is correct but the justification does not use the derived expression or ratio reasoning. The rubric requires tracing the change through the mathematical relationship.)

3. Part (c): A student claims that the orbital period depends on the mass of the satellite. Evaluate this claim using your derived expression.

   Rubric: Point earned only if the response states that the derived expression contains no satellite mass term, concludes the period is independent of satellite mass, and cites the derived expression as evidence. A bare statement that mass does not matter without referencing the expression is insufficient.

   Earns the point: The derived expression T equals 2 pi r to the three halves divided by the square root of GM contains no satellite mass m. The satellite mass canceled when gravitational force was equated to centripetal force. Therefore the orbital period does not depend on the satellite's mass, and the student's claim is incorrect.

   Loses the point: The mass of the satellite does not affect the period because gravity acts on all masses equally. (Correct physics intuition but does not reference the derived expression as required by the rubric. The worked derivation is the evidence the rubric is asking students to cite.)

Across all three parts the same principle applies: the derivation must be shown step by step, and the qualitative prediction must trace explicitly through the mathematical relationship rather than stating a conclusion from physical intuition alone. The 2023 Chief Reader Report for AP Physics 1 noted that the most common failure on QQT questions was submitting an unsupported final expression on the derivation part and then relying on intuitive language rather than ratio reasoning on the qualitative part. Practicing QQT questions with the scoring guideline open shows you exactly what level of algebraic detail Readers require.

Common AP Physics 1 FRQ mistakes

1. 01

   Submitting an unsupported final expression on Quantitative Qualitative Translation derivations

   The single most cited QQT failure across multiple Chief Reader Reports: a student writes the correct final algebraic expression with no derivation steps, and Readers cannot award any derivation points. The rubric is explicit that each algebraic manipulation must be shown. A student who knows the answer but skips the algebra earns zero on the derivation section even when the final expression is correct. Write every step from the starting equation through to the final result.

2. 02

   Paragraph Length Responses that list equations instead of constructing an argument

   Chief Reader Reports consistently note that students respond to the Paragraph Length Response by writing a series of equations with minimal connecting prose. Readers award points for the quality and logical sequence of the argument, not for the presence of equations. A response that states F equals ma and then KE equals one half mv squared without explaining what each equation means in the context of the scenario earns very few points. Write complete sentences that connect physics principles to the described situation and explain why each step follows from the previous one.

3. 03

   Experimental Design procedures that do not actually test the stated hypothesis

   On Experimental Design questions, students lose procedure points when their described method would not produce data that tests the relationship the question identifies. Common failures include: describing the measurement setup without specifying how to vary the independent variable across a range, failing to state which variable is held constant (and why holding it constant matters), and describing a procedure that would measure the wrong quantity. The rubric awards points for a procedure that someone could execute and that would yield the graph the student predicts.

4. 04

   Applying conservation of momentum without defining the system and conditions

   Chief Reader Reports flag responses on momentum and impulse questions that state momentum is conserved without specifying for which system and under what conditions. The rubric requires that a complete justification identify the system (for example, the two objects treated as a single system) and the condition under which momentum is conserved (no net external force on the system in the direction of motion during the collision interval). Stating momentum is conserved as a fact without the system and condition earns no conservation justification point.

5. 05

   Free body diagrams with missing forces, unlabeled arrows, or incorrect directions

   On Experimental Design and Short Answer questions that require a free body diagram, students frequently omit forces (such as friction or the normal force on an inclined surface), draw arrows of equal length when the magnitudes are not equal, or point arrows in the wrong direction. Chief Reader Reports note that diagrams missing the correct force count and direction typically earn zero diagram points even when the subsequent calculation is correct. Each force arrow must be labeled by name (or symbol), must point in the physically correct direction, and the diagram must include every force acting on the specified object.

6. 06

   Units errors and missing units on final numerical answers in Short Answer questions

   Short Answer questions with a numerical calculation component frequently specify that the correct unit is required to earn the answer point. Chief Reader Reports note that students who correctly execute the algebra and arrive at the right magnitude but omit or misstate the unit lose the answer point. This is a one habit fix: always check that the unit of the final answer matches the unit of the quantity the question asked for, and write it explicitly after the number.

How to practice AP Physics 1 FRQs effectively

Work each question type under timed conditions, then score yourself part by part against the official guideline.

The highest return practice for AP Physics 1 FRQs is not reading the questions, it is working them under realistic time pressure and then scoring yourself line by line against that year's official scoring guideline. The archive above links directly to College Board's hosted FRQ booklets for every year from 2019 to 2025, and the scoring guidelines are at the same official archive. Work one Experimental Design question in 25 minutes, score it against the rubric, and write down every point you missed and the exact requirement you did not meet. After three or four sessions the pattern of your losses becomes visible and almost always traces to a structural habit (missing variable identification, skipping derivation steps, writing equations instead of prose) rather than to missing physics content. Rotate across question types so you practice all three modes: planning for Experimental Design, algebraic derivation for Quantitative Qualitative Translation, and argumentation for the Paragraph Length Response. The Tutorioo AP Score Predictor can help you estimate how your FRQ practice performance maps to a projected composite score.

1. 1

   Start the 90 minutes by reading all five questions and noting which question type each is. Experimental Design, Quantitative Qualitative Translation, and Short Answer each require a different mental mode: planning, algebraic derivation, and focused justification. Switching between modes is faster when you know what is coming.

2. 2

   Budget your time before writing: approximately 25 minutes for Experimental Design, 20 minutes for Quantitative Qualitative Translation, and 13 minutes for each Short Answer question. If you spend more than 30 minutes on any single question, move on and return.

3. 3

   On the Quantitative Qualitative Translation question, write every algebraic step from the starting physics principle to the final expression. Do not jump to the answer. The derivation points are worth more than the answer point, and Readers cannot award them for an unsupported result.

4. 4

   On the Experimental Design question, explicitly name all three variable types in your response: what you change (independent), what you measure (dependent), and at least two quantities you hold constant and why. Missing any one of these costs points even when the procedure description is otherwise excellent.

5. 5

   On the Paragraph Length Response, write in complete sentences that connect physics principles to the scenario. Each sentence should do two things: state a physics principle and explain how it applies to this specific situation. Equations embedded in prose are acceptable and often useful, but equations without explanatory sentences do not earn the argument points the rubric awards.

6. 6

   On any question that asks you to justify a claim using conservation of momentum, always name the system and state the condition (no net external force on the system) before invoking conservation. A bare statement that momentum is conserved earns no justification point.

7. 7

   When drawing free body diagrams, include every force on the named object, label each arrow by name or standard symbol, and draw arrow lengths proportional to relative magnitudes where that information is given. Then use those labeled arrows as the basis for your Newton's second law equation so Readers see the connection between the diagram and the algebra.

8. 8

   After completing a question under timed practice, score it against that year's official scoring guideline before reading the sample responses. Identify which exact point you missed and why. After a few cycles, the pattern of your point losses almost always traces to one or two structural habits rather than missing content.

9. 9

   Do not leave any part blank. There is no penalty for an incorrect response, and a partially correct attempt on every part accumulates more points than perfect answers on a subset of parts. A plausible physics attempt almost always earns at least one point per part.

10. 10

    Use units as a check on your algebra. If the units of your derived expression do not match the units of the quantity the question asked for, you made an algebraic error before writing the final expression. Catch this before moving on.
