Physics 1 free-response questions
Free-response questions (FRQs) are the part of the AP® Physics 1: Algebra-Based exam where you write your own answers. Here they're grouped the way the exam uses them. Write your answer, then score it yourself with the rubric and a model answer, or sign in for free AI scoring.
24 questions · 4 types
Mathematical routines (MR)
A multipart problem where you use math to analyze a physical situation. You draw or sketch a representation such as a free-body diagram or a graph, derive an equation using letters, calculate a numerical answer with units, and then make a claim or prediction and justify it with physics reasoning.
On the exam: Question 1 of 4. Section II has 4 questions in 95 minutes (50% of the exam score), one of each type in this order; calculator allowed. The CED suggests 20–25 minutes. Plan on about 22 minutes for one.

Translation between representations (TBR)
A multipart problem about one situation shown in several ways. You draw a diagram, derive equations, sketch or draw graphs, and then explain whether your answers agree with each other or use them to predict what happens when the situation changes.
On the exam: Question 2 of 4. Section II has 4 questions in 95 minutes (50% of the exam score), one of each type in this order; calculator allowed. The CED suggests 25–30 minutes. Plan on about 28 minutes for one.

Units 1, 2 and 4
Cart bouncing off a force sensor
12 points · about 28 minutes · calculator allowed
Experimental design and analysis (LAB)
A two-part lab question. First you design an experiment to answer a question: what you change, what you measure, the equipment and how you would analyze the data. Then you get a data table from a similar experiment, choose what to graph (often so the points fall on a straight line), plot it and use the slope, the intercept or the graph's shape to answer a question.
On the exam: Question 3 of 4. Section II has 4 questions in 95 minutes (50% of the exam score), one of each type in this order; calculator allowed. The CED suggests 25–30 minutes. Plan on about 27 minutes for one.
Unit 7
Measuring g with a pendulum
10 points · about 27 minutes · calculator allowed
Unit 2
Finding the coefficient of kinetic friction
10 points · about 27 minutes · calculator allowed
Units 1 and 8

10 points · about 27 minutes · calculator allowed
Unit 4
Finding a cart's mass from impulse
10 points · about 27 minutes · calculator allowed
Unit 3
Spring constant of a toy launcher
10 points · about 27 minutes · calculator allowed
Qualitative/quantitative translation (QQT)
A shorter multipart problem that connects reasoning in words with an equation. You make and justify a claim without equations, derive an equation from a physics principle, and then explain whether the two agree or use them to predict what happens in a changed situation.
On the exam: Question 4 of 4. Section II has 4 questions in 95 minutes (50% of the exam score), one of each type in this order; calculator allowed. The CED suggests 15–20 minutes. Plan on about 18 minutes for one.
