📊 Topic Confidence Tracker — 7 Areas

Rate your confidence in each topic. Newton's laws and rotation carry the most weight, so weak spots there cost the most points.

Kinematics~10-16%
Newton's Laws of Motion~17-23%
Work, Energy & Power~14-17%
Systems of Particles & Linear Momentum~14-17%
Rotation (Torque, Angular Momentum)~14-20%
Oscillations~5-8%
Gravitation~4-6%

🆕 What Changed in 2025 (and Stays for 2026)

AP Physics C: Mechanics was redesigned for May 2025, mainly to expand both sections. There are more multiple-choice questions with more time, and a fourth free-response question. Here is what changed:

How AP Physics C: Mechanics Scoring Works

The exam has two equally weighted sections. An equation sheet is provided and a calculator is allowed throughout. The composite below is out of 100 and maps to the 1-5 scale using cutoffs that move slightly each year.

SectionQuestionsTimeWeightRaw → Scaled
I: Multiple Choice40 Qs (4 choices)80 min50%40 → 50 pts

II-Q2: Translation (TBR)~25 min12 pts
II-Q3: Experimental Design (LAB)~25 min10 pts
II-Q4: Short Answer / Paragraph~25 min8 pts

Composite = (MCQ correct / 40) × 50 + (FRQ raw / 40) × 50 = out of 100. Each correct MCQ and each FRQ raw point is worth 1.25 composite points.

2025 AP Physics C: Mechanics Score Distributions

2025 was the first year of the redesigned exam. The pass rate was 73.2% with a mean of 3.30. The 3 was the most common score, and the bottom of the curve is heavier than on the algebra-based physics exams.

Because 2025 was the first year of the redesigned format (four FRQs instead of three, and a longer multiple-choice section), year-over-year trend lines reset here. Compared with the algebra-based physics exams, Physics C: Mechanics has both more 5s and more 1s — it rewards strong preparation and punishes gaps.

Exam Strategies by Section

📋Multiple Choice

Now only 4 choices — easier to eliminate. Draw free-body diagrams for forces problems. Use dimensional analysis. Calculator allowed but most problems are conceptual. Budget ~2 min per question. No penalty for guessing.

🔢Q1: Mathematical Routines

Show ALL derivation steps. Start with a fundamental principle (conservation law). Define variables clearly. Use symbolic math — plug in numbers only at the end. Label final answers. Common topics: momentum, energy, kinematics.

📊Q2: Translation (TBR)

Practice energy bar charts, graphs, and diagrams. Translate between words → equations → graphs. Conservation of energy is a frequent topic. Label graph axes with units. Be consistent between different representations.

🔬Q3: Experimental Design

Name specific equipment. Describe step-by-step procedure. Identify independent/dependent variables. Explain how to reduce uncertainty (repeat trials). Plot linear graph — relate slope to unknown. This is often the most points-rich FRQ.

Frequently Asked Questions

Two equal sections. 40 calculus-based MCQs (80 min) scale to 50 points and 4 FRQs (100 min, 40 raw points) scale to 50 points. The 100-point composite maps to the 1-5 scale.
The exam was redesigned: multiple choice went from 35 questions in 45 minutes to 40 questions in 80 minutes with 4 choices, and free response went from 3 questions in 45 minutes to 4 questions in 100 minutes. Prep from 2024 or earlier is out of date.
Yes, a scientific or graphing calculator is allowed on both sections, and an equation sheet is provided. Physics C has always allowed calculators.
In 2025, 73.2% of students scored a 3 or higher, with a mean of 3.30. The breakdown was 5: 21.7%, 4: 24.0%, 3: 27.5%, 2: 16.0%, 1: 10.8%.
Kinematics, Newton's laws of motion, work/energy/power, systems of particles and linear momentum, rotation, oscillations, and gravitation — the same mechanics as Physics 1 but treated with calculus.
Physics C uses calculus and goes deeper; Physics 1 is algebra-based and broader. Physics C: Mechanics is for engineering and physics majors and pairs with a separate Physics C: Electricity & Magnetism exam.
Yes. Formulas and constants are provided, so you do not memorize equations but must know which relationship to use and how to apply calculus.
During the May 2026 AP exam window. The exam runs 3 hours: 80 minutes of multiple choice and 100 minutes of free response. Check AP Central for the exact date.
