About 18% of AP Physics 1 students score a 5 — College Board rescaled the exam's scoring in 2025. The format also changed: it's now 40 MCQs (50%) and 3 FRQs (50%), with experimental design and written justification accounting for a major share of FRQ points. Knowing the physics isn't enough — you have to be able to explain it clearly.
AP Physics 1 Score Breakdown (2025+ Format)
- MCQ (50%): 40 questions in 80 minutes, including multi-select questions
- FRQ (50%): 3 free-response questions in 100 minutes: Experimental Design (12 pts), Paragraph Argument Short Answer or Quantitative/Qualitative Analysis (12 pts), and Short Answer (12 pts)
Highest-Priority Units
- Unit 1 (Kinematics) — 12–18%: Displacement, velocity, acceleration graphs. Know how to extract information from position-time, velocity-time, and acceleration-time graphs, and what it means when slope or area equals another quantity.
- Unit 2 (Dynamics) — 16–20%: Newton's Laws in multiple dimensions. Free-body diagrams are non-negotiable — draw them on every FRQ. Know how to apply F=ma in systems with friction, tension, and normal force.
- Unit 4 (Energy) — 20–28%: The highest-weight unit. Work-energy theorem, conservation of energy, power. Almost every exam includes a conservation of energy problem where students need to account for all energy transformations.
- Unit 5 (Momentum) — 12–18%: Impulse-momentum theorem, conservation of momentum, elastic vs. inelastic collisions. Collision problems appear in both MCQ and FRQ every year.
- Unit 7 (Torque and Rotational Motion) — 12–18%: Torque, rotational inertia, angular momentum conservation. Rotational analogs of translational motion (τ=Iα mirrors F=ma) are heavily tested and often confused.
The FRQ Justification Format
AP Physics 1 FRQs require you to justify every claim with physics principles. A numerical answer alone earns no credit on qualitative questions. The graders look for: (1) identify the relevant principle, (2) explain why it applies, (3) connect it to the specific scenario. Example:
- No credit: "The ball moves faster at the bottom."
- Full credit: "As the ball descends, gravitational potential energy converts to kinetic energy. Since the system is conservative (no friction), the total mechanical energy remains constant. Therefore the decrease in height corresponds to an equal increase in kinetic energy — so the ball moves faster at the bottom."
Experimental Design Questions
The experimental design FRQ (12 pts) is the highest single-question point value on the exam. Practice the structure: (1) identify the independent and dependent variables, (2) describe how to hold all other variables constant, (3) explain how to collect and analyze the data to test the hypothesis, (4) predict what the data would look like if your hypothesis is correct. Students who practice this structure 5–6 times before the exam reliably score 10–12 points.
