§ 3Laws & Principles
Each card opens to show Statement / Applies when / Equation / Why it matters. Click a card to expand — and try to recall all four before you do.
§ 4Must-Know Equations
Gold dots = on the official AP Physics 1 equation sheet. The sheet gives you symbols, not understanding — know what each variable means and when the equation is legal to use.
§ 5Learning Objectives
Click a question to reveal a model answer. These map to the College Board’s learning objectives for this unit — if you can answer each cold, you own the unit.
§ 6Multiple-Choice Practice
Multiple choice is 50% of the exam (40 questions, 80 minutes). Fluids questions reward ratio reasoning — density ratios, area ratios, depth ratios — more than heavy algebra. Explanations appear after you choose.
§ 7Free-Response Workbook
The exam has exactly four FRQs — Mathematical Routines (10 pts), Translation Between Representations (12 pts), Experimental Design & Analysis (10 pts), and Qualitative/Quantitative Translation (8 pts). One of each is below. Write your response first, then reveal the model.
§ 8Design an Experiment
Experimental Design & Analysis is a guaranteed FRQ. Work through each phase of this investigation before revealing the analysis — the readers score your design choices, your data handling, and your reasoning about uncertainty.
§ 9Argumentation & Reasoning
AP Physics rewards claim → evidence → reasoning in words, not just algebra. Practice building the verbal argument — these are the “explain without equations” questions that separate 4s from 5s.
§ 10Landmark Experiments
The experiments that built this unit. Exam questions love to recycle these setups — know what each one showed and how.
§ 11Common Pitfalls
The specific mistakes students make over and over on Unit 8 questions.
