AP Physics 1 Study Guide
AP Physics 1 (algebra-based) covers mechanics, waves, and a foundation of other physics topics, with a 2026 format update to 40 MCQ and 4 FRQs worth 15 points each. The exam consistently rewards experimental design and using multiple representations (graphs, diagrams, equations) to justify an answer, not just a final numeric result.

Unit 3: Circular Motion and Gravitation
Uniform circular motion and gravitational force.
Unit 4: Energy
Work, energy, and the work-energy theorem.
Unit 5: Momentum
Momentum, impulse, and collisions.
Unit 6: Simple Harmonic Motion
Oscillations, springs, and pendulums.
Unit 7: Torque and Rotational Motion
Rotational kinematics, torque, and angular momentum.
Unit 8: Fluids
Fluid statics and dynamics — added to the course in recent revisions.

Common Mistakes to Avoid
- Giving a numeric answer without the required justification — Physics 1 FRQs are graded on reasoning (free-body diagrams, equations, explanations), not just a final number.
- Mixing up mass and weight, or forgetting that normal force isn't always equal to weight.
- On experimental-design FRQs, proposing a procedure without identifying and controlling the relevant variables — a frequently tested and frequently missed skill.
- Not connecting multiple representations (a graph, an equation, and a verbal explanation should all tell the same consistent story) when a question asks for justification across representations.
