AP Physics C: Mechanics Study Plan for a 5 (16 Weeks)

Format of the AP Physics C: Mechanics exam

AP Physics C: Mechanics is a calculus-based exam with two equally weighted sections. Section one has 42 multiple-choice questions in 85 minutes, and section two has 4 free-response questions (FRQs) in 95 minutes, so the whole exam takes 3 hours (this is the format from May 2027; the 2025 and 2026 exams had 40 questions in 80 minutes and 100 minutes for the FRQs, and earlier released exams had 35 questions and 3 FRQs in 90 minutes, so use older papers for content, not pacing). A calculator is allowed in both sections and a formula sheet is supplied. Scores run from 1 to 5. In May 2026, 20 percent of students earned a 5, a little above most AP sciences, though earning one still takes disciplined preparation.

The content falls into seven units: kinematics, force and translational dynamics, work/energy/power, linear momentum, torque and rotational dynamics, energy and momentum of rotating systems, and oscillations. Rotation (Units 5 and 6) accounts for roughly 20 to 30 percent of the multiple-choice section. It is the hardest conceptually, and the one students most often leave under-prepared.

The calculus you need first

Before the course material will make sense at the level the exam tests, you need working command of single-variable differential and integral calculus. In particular, be comfortable with:

• Derivatives of polynomial, trigonometric and exponential functions
• The chain rule and product rule
• Definite and indefinite integrals, including integration by substitution
• How a function, its derivative and its integral relate in kinematics (position, velocity, acceleration)

Tutors who work with strong students find that stalled progress in this course usually comes from calculus fluency, not physics intuition. If you cannot differentiate or integrate quickly, exam time goes to computation instead of reasoning. If your calculus needs work, use the first two weeks of the plan below to build it up.

How it differs from AP Physics 1, 2 and IB Physics HL

AP Physics 1 and 2 are algebra-based. AP Physics C: Mechanics uses calculus throughout, from deriving the kinematic equations to solving rotational dynamics, and the conceptual depth is much greater. IB Physics HL covers similar ground with less calculus and puts more weight on experimental design and data analysis through its internal assessment. For the mechanics topics they share, Physics C is the more mathematically rigorous of the two. IB Physics HL, however, covers a wider range overall, including wave optics and quantum physics, which AP Physics C leaves out.

A 16-week plan for a 5

This plan assumes about 6 to 8 hours of focused study a week and a May exam, so a start in late January or early February is typical. Shift the dates to suit your own calendar.

1. Weeks 1 to 2: Calculus review and kinematics. Revisit derivatives and integrals as they apply to motion. Get the position-velocity-acceleration relationships solid in one and two dimensions. Finish 2 to 3 past FRQ kinematics problems.
2. Weeks 3 to 4: Newton’s laws and applications. Work through force systems, friction, circular motion and constraint problems. Draw a free-body diagram for every problem before writing a single equation.
3. Weeks 5 to 6: Work, energy and power. Derive the work-energy theorem with integration. Be clear on conservative versus non-conservative forces. Practise problems with variable forces, where you must integrate to find the work.
4. Weeks 7 to 8: Momentum and impulse. Cover linear momentum, the impulse-momentum theorem and collisions (elastic and inelastic). Do center-of-mass problems for systems of particles.
5. Weeks 9 to 11: Rotation, the longest unit. Study torque, rotational kinematics, moment of inertia, rotational kinetic energy and angular momentum. Use calculus to derive moments of inertia for standard shapes. Rolling without slipping deserves its own attention. Allow 3 full weeks.
6. Week 12: Oscillations. Derive simple harmonic motion from Newton’s second law. Learn the period formulas for spring-mass and pendulum systems, and see how energy is conserved in SHM.
7. Week 13: Gravitation. Review Newton’s law of gravitation, gravitational potential energy and the motion of orbiting systems. Practise deriving orbital period and speed.
8. Weeks 14 to 15: Full practice exams. Sit two complete released AP Physics C: Mechanics exams under timed conditions. Go over every mistake by looking at the concept behind it, not just the arithmetic.
9. Week 16: Targeted review and FRQ strategy. Return to your weakest unit, as shown by the practice exams. Read the FRQ scoring rubrics to see where partial credit is given.

Strategy for the free-response section

In AP Physics C: Mechanics, FRQ scoring rewards a clear chain of logic more than a correct final number. Experienced teachers advise showing your setup every time, naming the principle you are using (conservation of energy, or Newton’s second law in rotational form, for example), writing the equation in symbols before you substitute numbers, and defining any variable you introduce. Partial credit is explicitly given for a correct setup even if the final calculation has an error. A blank answer earns zero, while an incomplete but logical attempt can pick up several points; the sample questions in the course description are worth between 8 and 12 points each.
