AP Physics 1 FRQs are graded by trained AP readers using detailed rubrics developed by College Board. Every point has explicit criteria. Understanding the rubric structure before reviewing specific questions helps you see exactly which parts of your responses earn or lose credit.
| Point Type | What It Requires | Common Error That Loses This Point |
| Fundamental Principle Statement | Write the correct foundational equation or principle by name before deriving. Example: ‘Conservation of momentum: Σp_before = Σp_after’ | Starting algebra without stating the principle – even if all subsequent work is correct, this criterion is not awarded |
| Symbolic Derivation | Show every algebraic step from the principle to the final expression using only the requested variables | Plugging in numbers before deriving symbolically; including extra variables not listed in the ‘express in terms of’ instruction |
| Numerical Calculation | Substitute correctly, compute the final number, and include correct units | Correct setup with wrong arithmetic; correct number missing units; setup without completing calculation |
| Free-Body / Vector Diagram | Correct arrows labeled and starting from the dot; correct relative lengths for different magnitudes | Arrows pointing wrong direction; missing labels; arrows not originating from the specified dot; incorrect relative lengths |
| Graph Construction | Labeled axes with units; appropriate scale; correctly plotted data; best-fit line through the data (not connecting dots) | Missing units on axes; connecting data points instead of a best-fit line; y-axis labeled with raw measurement instead of calculated quantity (e.g., v instead of v²) |
Question 1 is a 10-point Mathematical Routines (MR) FRQ focused on projectile motion and fluids. Students must apply kinematics and the continuity equation to a fountain nozzle launching water droplets at angle θ₀ with speed v₀. The problem tests symbolic derivation, energy relationships, and fluid flow concepts from AP Physics 1 Units 1 and 8.
| Q1 – Speed of Water Exiting the Nozzle (3 pts) Derive an expression for the speed v₀ of the water exiting the nozzle. Express your final answer in terms of θ₀, h₁, and physical constants as appropriate. |
| ✅ WORKED ANSWER & SCORING GUIDE FUNDAMENTAL PRINCIPLE (required starting point): Kinematics: At maximum height, the vertical component of velocity = 0. v_y² = v_y0² – 2g·Δy DERIVATION: Vertical component at launch: v_y0 = v₀ sin(θ₀) At maximum height h₁, vertical velocity = 0: 0 = (v₀ sin θ₀)² – 2g·h₁ (v₀ sin θ₀)² = 2gh₁ v₀² sin²(θ₀) = 2gh₁ v₀² = 2gh₁ / sin²(θ₀) FINAL ANSWER: v₀ = √(2gh₁) / sin(θ₀) SCORING CRITERIA: • 1 pt: Correctly identifying that vertical velocity = 0 at maximum height h₁ (or using energy conservation with correct energy terms) • 1 pt: Correct algebraic derivation leading to v₀² sin²(θ₀) = 2gh₁ • 1 pt: Correct final expression v₀ = √(2gh₁)/sin(θ₀) expressed only in terms of θ₀, h₁, and g |
Question 2 is a 12-point Translation Between Representations (TBR) FRQ focused on momentum and collision analysis. Students apply conservation of linear momentum, Newton’s Third Law, kinetic energy, and center-of-mass motion to a collision between two disks on a frictionless surface.
Setup: Disk R (mass m0m_0m0) moves in the +x+x+x direction at speed v0v_0v0, while Disk S (mass 3m03m_03m0) starts at rest. After the collision, Disk R moves in the −x-x−x direction at speed v0/2v_0/2v0/2.
| Q2 – Part A: Momentum Vectors After Collision (4 pts) Draw arrows on Figure 3 to represent the momentum vectors of Disk R and Disk S immediately after the collision. Arrow lengths must be consistent with the scale shown in Figure 2. If momentum is zero, write p = 0. |
| ✅ WORKED ANSWER & SCORING GUIDE ANALYSIS – Apply conservation of momentum: BEFORE collision: p_R,before = m₀v₀ (+x direction) p_S,before = 3m₀(0) = 0 Total: p_total = m₀v₀ (+x direction) AFTER collision: p_R,after = m₀(-v₀/2) = -m₀v₀/2 (-x direction, leftward) Conservation: p_R,after + p_S,after = m₀v₀ -m₀v₀/2 + p_S,after = m₀v₀ p_S,after = m₀v₀ + m₀v₀/2 = (3/2)m₀v₀ (+x direction) VECTOR DIAGRAM INSTRUCTIONS: If the original Disk R pre-collision arrow has length L (representing m₀v₀): • Disk R after: Arrow pointing LEFT (-x), length = L/2 (half the original) • Disk S after: Arrow pointing RIGHT (+x), length = 3L/2 (one-and-a-half times the original) SCORING CRITERIA: • 1 pt: Disk R arrow points in the -x direction (leftward) • 1 pt: Disk S arrow points in the +x direction (rightward) • 1 pt: Disk R arrow length is half the original pre-collision arrow length • 1 pt: Disk S arrow length is 3/2 times the original pre-collision arrow length |
Question 3 is an Experimental Design (ED) FRQ worth 10 points with a suggested time of 25 minutes. It tests friction and energy (AP Physics 1 Units 2–3), experimental design, data linearization, and graphical analysis. This question has two separate experimental setups: Parts A–B use a curved ramp to a horizontal surface (meterstick only); Parts C–D use an inclined ramp with a photogate and data table
Setup 1: A block of unknown mass slides down a frictionless curved ramp onto a horizontal surface with friction. Students have only a meterstick available.
| Q3 – Part A: What to Measure and How to Reduce Uncertainty (2 pts) A(i): Indicate which quantities the students could measure using only a meterstick to determine μk using a linear graph. A(ii): Briefly describe a method to reduce experimental uncertainty in those measurements. |
| WORKED ANSWER & SCORING GUIDE PART A(i) – MEASURABLE QUANTITIES: The students should measure: (1) Height h: the vertical height of the release point above the horizontal surface (measured with the meterstick along the ramp geometry) (2) Sliding distance d: the horizontal distance the block travels on the flat surface before stopping Physical basis: On the ramp (no friction): (1/2)mv² = mgh → v² = 2gh at the bottom. On the horizontal surface (friction only): Work done by friction = μk·mg·d = kinetic energy at bottom = (1/2)mv². Combining: μk·mg·d = mgh → μk·d = h → h = μk·d This is a linear relationship: graphing h vs. d gives slope = μk. PART A(ii) – REDUCING UNCERTAINTY: For each release height h, repeat the trial multiple times (at least 3) and calculate the average sliding distance d. Averaging across multiple trials reduces random error caused by minor variations in the block’s path or friction surface. Additionally, mark the starting position of the block precisely before each trial using the meterstick to ensure consistent measurement reference points. SCORING CRITERIA: • 1 pt: Correctly identifying height h and horizontal sliding distance d as the two measurable quantities • 1 pt: Viable method to reduce uncertainty – multiple trials and averaging is the primary acceptable answer |
Question 4 is an 8-point Qualitative/Quantitative Translation (QQT) FRQ focused on rotational dynamics. Students apply rotational inertia concepts, angular speed relationships, and the rotational work-energy theorem from AP Physics 1 Unit 5.
Setup: Two rotating toys, X and Y, have the same radius r0r_0r0, but Toy Y has half the rotational inertia of Toy X (IY=12IX)\left(I_Y=\frac{1}{2}I_X\right)(IY=21IX). A constant force F0F_0F0 pulls a string of length ℓ0\ell_0ℓ0 wrapped around each toy, causing them to spin with angular speeds ωX\omega_XωX and ωY\omega_YωY.
| Q4 – Part A: Which Toy Spins Faster? (3 pts) Indicate whether ω_Y is greater than, less than, or equal to ω_X. Justify using qualitative reasoning beyond referencing equations. |
| WORKED ANSWER & SCORING GUIDE ANSWER: ω_Y > ω_X QUALITATIVE JUSTIFICATION (must be a cause-effect chain, not just equation citation): Step 1 – Same work input: The same constant force F₀ acts through the same string length ℓ₀ on both toys. Therefore, the same amount of work W = F₀·ℓ₀ is done on each toy. Step 2 – Less rotational inertia means less resistance to spinning: Toy Y has half the rotational inertia of Toy X (I_Y = I_X/2). Rotational inertia is a measure of how difficult it is to change an object’s rotational speed. A lower rotational inertia means the toy is easier to spin up. Step 3 – Conclusion: With the same work input and lower resistance to rotation, Toy Y reaches a greater angular speed than Toy X. Analogy for reasoning: Just as a lighter ball accelerates more than a heavier ball under the same push (F = ma), a toy with lower rotational inertia ‘spins up’ more under the same work input. SCORING CRITERIA: • 1 pt: Correct answer ω_Y > ω_X • 1 pt: Correctly identifying that the work done on each toy is equal (same force, same string length) • 1 pt: Correctly reasoning that lower rotational inertia → higher angular speed for the same work input |

AP Physics 1 uses four standardized FRQ types that appear in a consistent order on every exam. College Board designs each type to assess a different dimension of physics understanding. Knowing what each type demands before exam day lets you recognize instantly what is being asked – and how to structure your response.
| Type | Abbrev. | 2026 Question | Core Skill | How to Earn Full Credit |
| Mathematical Routines | MR | Q1: Fountain (10 pts) | Symbolic derivation from fundamental principles; numerical calculation | State principle → derive symbolically → calculate numerically → include units. Express final answer using only specified variables. |
| Translation Between Representations | TBR | Q2: Disk Collision (12 pts) | Connect vectors, graphs, equations, and written descriptions of the same physical situation | Momentum vector lengths must be to scale. Graph slopes/shapes must match equations. Every representation must be internally consistent. |
| Experimental Design | ED | Q3: Friction Lab (10 pts) | Design procedures, identify variables, linearize data, construct graphs, calculate physical constants from graphs | Label axes with calculated quantities (v², not v). Draw best-fit lines (not dot-to-dot). Calculate from the LINE slope, not from a single data point. |
| Qualitative/Quantitative Translation | QQT | Q4: Spinning Toys (8 pts) | Explain behavior qualitatively; derive an equation confirming the prediction; check consistency | Qualitative reasoning must be a causal chain. Consistency check must reference specific terms in the derived equation – not just say ‘yes.’ |
Every 2026 AP Physics 1 FRQ is built around specific principles from the College Board AP Physics 1 Course and Exam Description (CED). Knowing which unit and principle is being tested shapes your entire approach to each question.
| Question | AP Physics 1 Units | Core Principle | Key Equations |
| Q1: Fountain Droplet | Unit 1 (Kinematics) + Unit 8 (Fluids) | Projectile motion – constant horizontal velocity, uniform vertical deceleration g; Continuity equation – volume flow rate Q = Av is conserved | v_y² = v_y0² − 2gh; v₀ = √(2gh₁)/sinθ₀; Q = Av = πr₀²·v₀ |
| Q2: Disk Collision | Unit 4 (Linear Momentum) + Unit 1 (Kinematics) | Conservation of linear momentum in absence of external horizontal forces; Newton’s Third Law – equal and opposite impulses; Center of mass moves at constant velocity when F_net = 0 | Σp_before = Σp_after; KE = (1/2)mv²; v_cm = Σ(m·v)/Σm |
| Q3: Friction Lab | Unit 2 (Forces) + Unit 3 (Work, Energy, Power) | Energy conservation on frictionless ramp; Work-energy theorem on rough surface; Linearization: v² = 2g(sinθ − μk cosθ)·d | (1/2)mv² = mgh; W_friction = μk·mg·d; h = μk·d (linearized) |
| Q4: Spinning Toys | Unit 5 (Rotational Dynamics) | Work-energy theorem for rotation – W_net = ΔKE_rot; Work done by string = F·ℓ₀; ω inversely proportional to √I for same work input | W = F₀·ℓ₀; (1/2)Iω² = F₀ℓ₀; ω = √(2F₀ℓ₀/I) |
College Board’s Chief Reader Reports for AP Physics 1 (2022–2025) identify the same categories of errors year after year. These six mistakes account for the majority of lost FRQ points across all question types. Avoiding them is the fastest way to improve your score.
