AP Physics C Mechanics Rotation Revision
Rotation is where many AP Physics C Mechanics scores stall — torque, I, angular momentum, and rolling without slipping combine calculus and diagrams.
Hub: AP Physics C Mechanics · Newton’s laws · FRQs.
Core checklist
| Topic | Must know |
|---|---|
| Torque | τ = r × F; pivot choice |
| Rotational kinematics | ω, α links to linear v, a |
| Moment of inertia | Common shapes; parallel axis if in CED |
| Angular momentum | Conservation when τ_ext = 0 |
| Rolling | Energy split translational + rotational |
Practice order
- Pure rotation (fixed axis) FRQs.
- Rolling without slipping — energy method vs Newton.
- Mixed translation + rotation collisions — momentum.
Frequently asked questions
Is rotation on AP Physics 1?
Yes but algebra depth — C goes further with calculus.
Most common FRQ mistake?
Wrong axis or missing direction on torque.
