AP Physics 1 Study Guide: 8 Units, 2027 Exam Format & Resources
Use this guide to plan the course, review the current eight-unit framework, understand the May 2027 hybrid digital exam, and move directly into Sly Academy's topic notes. The outline follows the current College Board course and exam description—not the older 10-unit sequence.
What AP Physics 1 covers
AP Physics 1: Algebra-Based is an introductory college-level physics course. It uses algebra, graphs, diagrams, experiments, and written reasoning to study motion and interactions. The goal is not to memorize a long equation list. Students need to create representations, choose a mathematical pathway, analyze data, design investigations, and justify claims with physical principles.
The current framework centers on five ideas that reappear across units: systems, fields, force interactions, change, and conservation. That is why momentum, energy, and angular momentum should be studied as connected models rather than isolated chapters.
College Board does not list a formal prerequisite, but students should be comfortable with algebra, interpreting graphs, rearranging equations, proportional reasoning, geometry, and basic trigonometry. If you are still choosing courses, compare the full AP subjects list and ask your school about its local placement requirements.
The 8 AP Physics 1 units for 2026–27
The percentages below are the official weighting ranges for the multiple-choice section. They help you prioritize review, but every unit can also appear in a free-response question or in a question that combines several ideas.
Unit 1: Kinematics
Represent position, velocity, and acceleration with words, diagrams, equations, and graphs. Practice translating between representations instead of treating each formula as a separate trick.
Review position, velocity, and accelerationUnit 2: Force and Translational Dynamics
Define a system, draw free-body diagrams, apply Newton's laws, and connect net force to acceleration. Include friction, springs, gravity, and circular-motion applications.
Study forces and translational dynamicsUnit 3: Work, Energy, and Power
Use work-energy reasoning, energy bar charts, conservation of energy, potential-energy functions, and power. State the system before deciding whether energy is transferred or transformed.
Open the work and energy notesUnit 4: Linear Momentum
Connect impulse to momentum change and analyze collisions with a clearly defined system. Distinguish conservation of momentum from conservation of mechanical energy.
Review momentum and impulseUnit 5: Torque and Rotational Dynamics
Relate torque, moment of inertia, angular acceleration, and rotational kinematics. Choose a pivot strategically and keep sign conventions consistent.
Study torque and rotational motionUnit 6: Energy and Momentum of Rotating Systems
Apply rotational kinetic energy and angular-momentum conservation. Compare translational and rotational quantities without assuming the equations are interchangeable.
Learn conservation of angular momentumUnit 7: Oscillations
Model springs and pendulums with equilibrium, restoring forces, energy, period, amplitude, and phase. Use graphs to connect position, velocity, acceleration, and energy over time.
Strengthen simple harmonic motionUnit 8: Fluids
Work with density, pressure, buoyancy, continuity, and conservation of energy in fluid flow. Draw a system diagram and track assumptions before applying a fluid relationship.
Review the fluids foundationAP Physics 1 exam format for May 2027
The May 2027 AP Physics 1 exam is scheduled for Wednesday, May 5, 2027, Session 2. It is a hybrid digital exam: students answer multiple-choice questions and view free-response prompts in Bluebook, then handwrite free-response answers in a paper booklet.
| Section | Questions | Time | Score |
|---|---|---|---|
| Section I: Multiple Choice | 42 | 85 minutes | 50% |
| Section II: Free Response | 4 | 95 minutes | 50% |
The four free-response questions assess mathematical routines, translation between representations, experimental design and analysis, and qualitative/quantitative translation. A permitted calculator may be used on both sections, and reference information is supplied for the exam. Practice writing complete reasoning: an unsupported equation or numerical answer may not earn all available points.
After a timed practice set, use the AP Physics 1 score calculator only as a planning estimate. Official score cutoffs can vary, so the strongest feedback comes from the released scoring guidelines and your error log.
Kinematics calculator
Use this preserved study tool to check constant-acceleration practice. Enter values with consistent SI units; the calculator is not a substitute for showing setup and reasoning.
A practical AP Physics 1 study plan
1. Diagnose
Complete a mixed set without notes. Label each miss as a concept error, representation error, algebra error, experiment-design error, or time-management issue.
2. Rebuild
Review one weak idea, create a diagram or graph from memory, and solve a short sequence that moves from conceptual reasoning to calculation.
3. Retrieve
Return to the idea after one day and one week. Mix it with earlier units so you learn to select a model rather than follow a chapter cue.
Use labs as exam preparation
AP Physics 1 courses should devote at least 25 percent of instructional time to hands-on laboratory investigations. Keep a lab notebook or digital portfolio with the question, variables, procedure, raw data, graphs, uncertainty, conclusion, and possible improvements. Colleges may ask for this evidence when considering laboratory credit.
Practice the science practices
- Create representations: free-body diagrams, energy and momentum representations, graphs, tables, and experimental schematics.
- Use mathematical routines: derive symbolic relationships before substituting numbers; track units and proportional dependence.
- Question and argue scientifically: design a procedure, identify measurable quantities, and justify a claim with data or a physical law.
If you want a more calculus-intensive mechanics route, compare the AP Physics C: Mechanics study guide. To continue into thermodynamics, electricity, magnetism, optics, quantum, and nuclear physics, use the AP Physics 2 notes and study guides.
