AP Physics
C: Mechanics
Use Calculus to describe motion. Essential for Physics, Engineering, and Computer Science applications at top universities. It has one of the highest AP STEM 5-rate distributions (~27.1%). Redesigned for 2024-25 with 7 units. Students are expected to have completed Calculus AB+.
Before you begin, understand how the College Board scores it.
AP Physics C: Mechanics has a short but dense structure: 40 MCQ + 4 FRQ in 1 hour 45 minutes (Sections I and II are each about 50 minutes). FRQ requires Calculus (derivatives and integrals) — the major difference from Physics 1. Understanding the structure helps your child allocate study time to the right priorities.
Score 5/5 distribution in 2024
According to College Board data, 27.1% of students worldwide earned a 5 on AP Physics C: Mechanics — the second-highest rate among AP Physics courses (behind only Physics C: E&M). The reason: a self-selected test-taking pool, with most students having completed Calculus AB or BC. Our students target a 5-rate 1.5-2 times higher by mastering all 7 units plus the 4 calculus-based FRQ formats under the official rubric.

Sample Question — Energy & Rotation FRQ.
This is a typical AP Physics C: Mechanics FRQ — Units 4-5 (Rotation + Energy). Students must apply energy integration and conservation of angular momentum.
Context: A uniform disk of mass M, radius R is mounted on a fixed axle through its center. A string is wrapped around the disk, and the other end supports an object of mass m. The system is initially at rest. At t = 0, the object is released and begins to fall.
Answer all 4 parts below:
- Draw the FBD separately for the disk and the mass m. Clearly label all forces (T, Mg, axle force, mg) (3 points).
- Apply Newton's Second Law to both translational motion (mass m) and rotational motion (disk). Find the linear acceleration a of mass m in terms of M, m, and g (the disk has moment of inertia I = ½MR²) (5 points).
- Use conservation of energy: find the speed v of mass m after it has fallen a distance h. Compare with the result from part (b) (4 points).
- Qualitative explanation: If the disk is replaced by a hoop of the same mass M and radius R (I = MR²), will acceleration a increase or decrease? Why? (3 points).
Part (a) — 3 points: FBD for mass m: T (up), mg (down). FBD for the disk: T at the rim (creating torque), Mg at the center, and axle force N from the support. Incorrect vectors or missing forces = minus 0.5 point per error.
Part (b) — 5 points: Mass m: mg − T = ma (1). Rotating disk: τ = Iα → TR = (½MR²)·(a/R) → T = ½Ma (2). Substitute (2) into (1): mg − ½Ma = ma → a = mg/(m + ½M) = 2mg/(2m + M).
Part (c) — 4 points: Conservation of energy: mgh = ½mv² + ½Iω² with ω = v/R, I = ½MR². Substitute: mgh = ½mv² + ¼Mv² → v = √(2mgh/(m + ½M)) = √(4mgh/(2m + M)). Check: v² = 2ah → ah = 2mgh/(2m + M)·h/2 ≈ consistent with constant acceleration.
Part (d) — 3 points: A hoop has I = MR², which is larger than the disk value I = ½MR² → it is "harder to rotate" → requires a larger resisting tension T → mass m moves downward more slowly, meaning a decreases. Quantitatively: a_hoop = mg/(m + M) < mg/(m + ½M) = a_disk.
→ Our tip: for Physics C: Mechanics rotation FRQs, always write Newton's Second Law separately for translational and rotational motion, then use the constraint a = αR to connect them. Part (d) in particular — the qualitative explanation — appears often and separates 5-level responses from 4-level responses.
