AP Physics C: Mechanics
What the calculus-based AP Physics C: Mechanics exam covers, how the current format works, how it's scored, and how to practice your way to a 5.
AP Physics C: Mechanics is a calculus-based, college-level introductory mechanics course and exam — motion, forces, energy, momentum, rotation, oscillations and gravitation. Under the current format the exam runs about 1 hour 45 minutes with roughly 40 multiple-choice questions and 4 free-response questions, scored from 1 to 5. Calculus is used throughout, a calculator is allowed and a formula sheet is provided. It's taken in May, and many colleges grant credit for a 3 or higher — confirm your target college's policy.
Two sections, one calculus-based mechanics course
The College Board expanded each Physics C exam in the current format. The exam now runs about 1 hour 45 minutes across two roughly equal sections — confirm the current numbers on College Board.
About 40 questions.
Single-select questions, many tied to graphs, diagrams and short scenarios. They reward reasoning about motion and forces — reading a position-time graph or ranking quantities matters as much as recall.
About 4 questions.
Multi-part problems that reward setting up equations, using calculus, sketching and labeling graphs, and explaining your reasoning. Partial credit comes from showing a clear method, not just a final number.
One 1–5 score.
The two sections combine into a single 1–5, weighted roughly equally. A 3 is "qualified"; a 4 or 5 is strong. Credit policies are set by each college — confirm yours.
Practice it, topic by topic.
Reading about mechanics isn't the same as working AP-style problems with calculus and learning from every miss. Start free and practice by topic.
What AP Physics C: Mechanics covers
- Kinematics — motion in one and two dimensions, using derivatives and integrals
- Newton's laws of motion — forces, free-body diagrams and dynamics
- Work, energy and power — the work-energy theorem and conservation of energy
- Systems of particles and linear momentum — impulse, collisions and center of mass
- Rotation — torque, rotational kinematics and dynamics, angular momentum
- Oscillations — simple harmonic motion and the simple pendulum
- Gravitation — Newton's law of gravity, orbits and gravitational energy
How to study for AP Physics C: Mechanics
- Get fluent with the calculus first — derivatives for velocity and acceleration, integrals for displacement and work.
- Drill free-body diagrams until they're automatic; most mechanics problems start there.
- Practice one topic at a time, then mix topics the way the exam does.
- Work the free-response by hand — show setups, units and labeled graphs for partial credit.
- Review every miss until the physics, not just the answer, is clear, and sit timed sets to build pace.
What makes AP Physics C: Mechanics different
Physics C: Mechanics is calculus-based. The same mechanics ideas become sharper because position, velocity, acceleration, force and energy are linked by derivatives and integrals.
| Area | What matters | Practice move |
|---|---|---|
| Calculus link | Rates and accumulation | Use derivatives for instantaneous motion and integrals for displacement, impulse or work. |
| Newtonian systems | Force as a model | Build equations from diagrams before solving differential or time-dependent relationships. |
| Rotation and oscillation | Analogous quantities | Map force to torque, mass to rotational inertia and linear motion to angular motion. |
| FRQ work | Symbolic setup | Show the governing equation and limits or initial conditions before the final numeric result. |
