AP Physics 1 at a glance
AP Physics 1 is a college-level, algebra-based introductory physics course capped by a May exam scored 1–5. As of the 2025–26 cycle the exam has 40 multiple-choice questions (80 minutes) and 4 free-response questions (100 minutes), with each section worth 50% of your score. A calculator and an official reference/equation sheet are allowed on the exam. This guide breaks down the format, the eight units and their weights, and how to study for a 4 or 5.
AP Physics 1 is part of the College Board's Advanced Placement program. Doing well can earn college credit or placement — though credit policies vary by school, with many colleges accepting a 3+ and selective ones wanting a 4 or 5.
What's on the AP Physics 1 exam (2025–26)
The exam recently changed. The MCQ section shrank from 50 to 40 questions, multi-select questions were removed, the number of FRQs dropped from 5 to 4, and the Fluids unit moved over from AP Physics 2. Here's the current structure:
| Section | Question type | # of questions | Time | Weight |
|---|---|---|---|---|
| I | Multiple choice (4 options, A–D) | 40 | 80 min | 50% |
| II | Free response (4 questions) | 4 | 100 min | 50% |
| Total | — | 44 | ~3 hours | 100% |
A few important details:
- Rights-only scoring. There is no penalty for a wrong multiple-choice answer, so never leave a blank — always guess.
- Calculator allowed on the exam, plus an official reference/equation sheet (provided in print and in the digital app) you don't have to memorize.
- Hybrid digital format. Most AP exams, including Physics 1, are now delivered in the Bluebook app. For Physics 1, you answer MCQs and read FRQ prompts on-screen but handwrite your free-response work in a paper booklet that's collected for scoring. This is still evolving year to year, so confirm the delivery method with your AP coordinator.
- Format changes ahead. The College Board has said the number of multiple-choice questions and the section timing will be updated starting with the May 2027 exam, so always check the latest Course and Exam Description (CED) for the year you're sitting.

The four free-response questions
The FRQ section is where many points are won or lost. The four questions map to specific reasoning skills (point values are approximate and can shift slightly year to year):
- Mathematical Routines — set up and execute a calculation to reach a numerical answer.
- Translation Between Representations — move between graphs, equations, diagrams, and words.
- Experimental Design and Analysis — design a lab procedure, analyze data, and justify conclusions.
- Qualitative/Quantitative Translation — connect a math result to a real-world physical explanation.
Across the four questions you're aiming for roughly 40–45 raw points total (check the latest scoring guidelines, since per-question values can change). Graders reward clear reasoning: show your equations, define your variables, and explain your steps in words even when a number is right.
The 8 units and their exam weights
The course is organized into eight units. The two dynamics/energy units dominate, so prioritize them. Approximate exam weights (always cross-check the latest Course and Exam Description):
| Unit | Topic | Approx. weight |
|---|---|---|
| 1 | Kinematics | 10–15% |
| 2 | Force & Translational Dynamics (Newton's laws) | 18–23% |
| 3 | Work, Energy & Power | 18–23% |
| 4 | Linear Momentum | 10–15% |
| 5 | Torque & Rotational Dynamics | 10–15% |
| 6 | Energy & Momentum of Rotating Systems | 5–8% |
| 7 | Oscillations (simple harmonic motion) | 5–8% |
| 8 | Fluids | 10–15% |
Note that "circular motion & gravitation" isn't a standalone unit anymore — that content is woven into the dynamics and energy units. The big takeaway: Units 2 and 3 alone can be roughly 40% of the exam, so master forces and energy first.
What each unit actually tests
- Kinematics: motion graphs, constant acceleration, projectile motion. Reading position-velocity-acceleration graphs is a recurring skill.
- Dynamics: free-body diagrams, , friction, tension, inclines. Drawing accurate free-body diagrams is the single highest-leverage skill in the course.
- Energy & Power: work-energy theorem, conservation of energy, springs. The conservation equation shows up constantly.
- Momentum: impulse-momentum theorem, conservation of momentum, elastic vs. inelastic collisions.
- Rotation (Units 5–6): torque, rotational inertia, angular momentum. Many students under-study this — don't.
- Oscillations: period of springs and pendulums, energy in SHM.
- Fluids: density, pressure, buoyancy (Archimedes), continuity, and Bernoulli's principle — the newest content, so older review books may skip it.
How AP Physics 1 is scored
Your raw points from both sections are combined (50/50) and converted to the 1–5 AP scale:
- 5 – extremely well qualified
- 4 – well qualified
- 3 – qualified
- 2 – possibly qualified
- 1 – no recommendation
The exact raw-point cutoffs are re-set each year through a process called equating, so there's no fixed percentage. On the redesigned 2025 exam, AP Physics 1 scores improved sharply: roughly 1 in 5 students earned a 5 and about two-thirds scored a 3 or higher, though a meaningful share still scored a 1 or 2. Score distributions move year to year, so check the latest official figures — but the bigger point holds: this exam rewards genuine conceptual mastery over memorization.

How to study for a 4 or 5
AP Physics 1 punishes passive studying. The students who score highest practice doing physics, not just reading it.
- Front-load Units 2 and 3. Forces and energy are the backbone of the exam and most other units build on them.
- Master free-body diagrams. If you can draw forces correctly, half the dynamics problems solve themselves.
- Practice explaining, not just calculating. FRQs increasingly ask why. Write full-sentence justifications and connect math to physical meaning.
- Use the reference sheet from day one. Since it's provided on exam day, train with it so you know exactly where each equation lives and which symbols mean what.
- Do timed, full-length practice. Pacing is real: ~2 minutes per MCQ and ~25 minutes per FRQ. Simulate exam conditions.
- Don't skip Fluids. It's newer to the course and easy to neglect, but it's worth a meaningful chunk of points.
The best preparation is repeated, realistic practice with honest feedback. Velacai offers realistic AP practice with exam-style multiple choice and free-response questions, AI grading on your written work, and a projected 1–5 score so you can target your weakest units before May. See pricing for plan details.
FAQ
Is AP Physics 1 hard?
Yes — it's widely considered one of the more challenging AP exams, mainly because it tests deep conceptual reasoning rather than plug-and-chug math. The algebra itself is manageable, but you must explain why physical situations behave the way they do. With consistent problem-solving practice and strong free-body-diagram skills, it's very doable.
What's a good score on AP Physics 1?
A 3 or higher is officially "qualified" and passing, and many colleges grant credit at a 3+. Because the exam is rigorous, a 4 is strong and a 5 is excellent. More selective universities often require a 4 or 5 for credit, so check your target schools' specific policies.
How is AP Physics 1 scored?
The multiple-choice section (40 questions) and free-response section (4 questions) are each worth 50%. Your combined raw score is converted to a 1–5 scale each year through equating. Multiple choice is rights-only, meaning wrong answers don't cost you points — so always answer every question.
Do you need AP Physics 1 before AP Physics 2 or C?
No — AP Physics 1 has no prerequisite beyond algebra and basic trig, and you can take Physics 2 or the calculus-based Physics C courses with or without it. That said, the mechanics foundation in Physics 1 makes the others significantly easier.
How many units are on AP Physics 1?
There are 8 units: kinematics, dynamics, work/energy/power, momentum, torque & rotational dynamics, energy & momentum of rotating systems, oscillations, and fluids. Units 2 (Dynamics) and 3 (Energy) carry the most exam weight, so prioritize them in your studying.
