It’s not you – it’s actually difficult
According to the College Board, for AP Physics 1 FRQs, students struggle the most with questions that require
- qualitative-quantitative translation
- experimental design
- data analysis
These three areas are in every single FRQ you’ll have to solve.
Additionally, a 2023 Nerd-notes survey of high school physics students found that over 81% of students struggle with applying concepts to new situations.
After helping 500 students score a 5 in just the past year, I made this post, to help you avoid falling into these statistics.
If you can apply our tips for the FRQs section, you chances of scoring in 90th percentile are within your reach.
Other interesting stats
- In 2021, the average score for the AP Physics 1 exam was 2.55 out of 5.
- On the 2021 exam, the most commonly missed FRQ was question 3
- According to a survey of high school physics students, 42% of students struggle with free-body diagrams. Learn how you can master FBD’s here.
- After teaching students for the last 7 years, the most difficult topic for students is angular momentum. Read our angular momentum speed review for a better understanding.
- Students also tend to struggle a bit with kinematics. Master kinematics with this guide.
- Most student’s miss out on “easy points” as they are unclear on how to word their answers in the FRQs.
Practice, then do some more
FRQ strategies are useless if you don’t apply them. We recommend taking anywhere between 20-30 full length FRQ throughout the course of the year.
Most importantly, make sure to obsess over your missed questions and why you got them wrong.
If you can do this with a tutor or teacher, your score will dramatically increase with every FRQ you do. Nerd-notes coaches promises our students a score improvement of over 50% within the first 10 practice FRQs.

Understand what college board looks for
AP Physics 1 students typically misunderstand what college board looks for.
Memorizing formula’s and concept simply isn’t enough. Here’s what they really want:
- Derivation
- Analysis
Derivation
Reasoning is your ability to solve a problem by filtering through concepts and then putting them together.
College board wants you to first reason conceptually, then apply it mathematically.
The end result is usually a uniquely derived formula.
Example of reasoning to derive a formula
Take a ramp of height \( h \), at an angle of \( 30^\circ \), that has a coefficient of static friction of \( 1 \), and a coefficient of kinetic friction of \( 0.5 \). What mass must a block weigh in order to start moving? What is the final velocity at the bottom of the ramp?
Lets break this down. We need to know about:
- About inclined ramps/trig
- Coefficients of static vs kinetic friction
- Velocity at end of the ramp
If you know what these mean individually you need REASONING to put it all together.
So let’s reason it out the first question: Since we are trying to find mass required to set the object in motion. We will reason drawing an FBD and applying forces is appropriate to map out our force vectors and use that to find net force later.
We also reason that in order for an object to move it must first overcome static friction. Thus we must use the force of static friction in our FBD and equation.
Now that we’ve reasoned all of this, we start deriving an equation with \(F_{\text{net}}=ma\). Here’s an article on how to quickly put together force questions.
The second part of the question asks: What is the final velocity at the bottom of the ramp? Can you use a bit of reasoning to put together a formula?
Proportional Analysis
College Board loves asking you to analyze.
- What happens to velocity when you increase radius?
- By what factor does mechanical energy change as you double work?
- What happens to x when you change y.
These are all questions you will frequently encounter in both FRQs and MCQs. I call these proportional analysis questions, that you can find on UBQ.
To answer these correctly you must first derive or use a given equation.
Next, you’ll need to figure our the relationship between two variables. Are they directly proportional or inversely proportional? Is it a linear, quadratic, or cubic relationship.
A simple example is asking what would happen to kinetic erngy if velocity doubled. Arrcoding to the kinetic energy eqaution:
\[KE = 1/2mv^2\]
we see that \(KE\) and \(v^2\) are directly proportional. Thus as \(v\) doubles \(KE\) will quadruple.
This is the type of analysis is what college board looks for.
If you are having trouble with reasoning or analysis, consider working with our professional AP Physics 1 tutors. We’ll share with you simple techniques that has helped over 500 of our students score 5’s.
Keep it short, keep it sweet
Always remember that its humans grading your FRQ. They might have already graded a 100 FRQs by the time they get to yours.
Do you want them reading through a dense paragraph, potentially missing something important?
Many points are lost on the FRQs, due to over explaining. Nerd notes tutors shows students if you TRULY understand the concepts, you can answer ALL questions in ONE sentence or less.
If you look at answer keys of the FRQs you’ll notice that most answers are only a sentence or two long. Sometimes just a formula is given for the answer.
That said, make it easy for your graders. Use a few short sentences and focus on the main idea. In fact, most our students here on nerd-notes, are trained to use formula’s to answer 90% of the questions! More on this below.
7 Key strategies to ace the FRQs
To help you prepare for the AP Physics 1 FRQs, here are some key strategies you can follow:
(1) Read the Question Carefully
Make sure you understand what the question is asking. Mass, velocity, momentum of object X, Y or both?
College board LOVES to throw in unnecessary jargon to confuse students. Avoid this by skim-reading. Underline only the key information in the question, such specific conditions or constraints. Is friction negligible, is the system open or closed?…etc.
(2) Start Immediately
A common mistake is re-reading the entire problem. It is not worth the time. Read what they are asking you to find, identify which concept to use, and start making equations.
(3) Use a Clear and Organized Method
When solving the problem, use a clear and organized method to show your work. This will make it easier for the grader to follow your thought process and give you partial credit if you make a mistake.
(4) Timing is key
There’s no point in understanding how to solve a problem if you can’t solve it quick enough.
There are 4 FRQs — consisting of roughly of 20 question parts altogether. Given you only get 100 minutes, a general rule of thumb is to take no longer than 3 minutes to solve each part.
The ONLY way to achieve this speed is to practice under timed conditions, to get used to the pace and pressure. Before taking the exam, you should know what 3 minutes “feels like.” This will allow you to keep a steady pace during the exam.
(5) Equations — your best friend
Imagine a lawyer presenting their case with no evidence. No one would believe them.
Similarly, many students make claims on thier FRQs without evidence. No grader would be persuaded to give you points.
Your evidence is your equations. Be good at deriving questions that you can use to make claims with. Here’s an example: the velocity of a block sliding down a friction of a ramp is proportional to the square root of the height it’s released from, according to (your derived formula) \(v = \sqrt{2gh}\).
(6) Check Your Units
This should be obvious. If you have extra time, quickly preform unit analysis to make sure you didn’t miss a square root or an entire number.
Have your calculator set to degrees. Make sure you
(7) Use Common Sense
If something is “missing,” it’s likely that it is right in front of you. In other words it is implied in the problem. College board loves to do this to test how well you know relationships between variables.
For example, a car moving at constant speed implies, no acceleration OR a centripetal acceleration. It could also mean that there’s no net force. And it could also mean that there is no change in momentum, and thus no impulse.
These are hints staring right at you. Get good at looking for these and you will solve problems with much more ease.
The AP Physics 1 FRQs can be challenging, but with the right strategies and practice, you can ace them and boost your exam score. Remember to read the question carefully, use a clear and organized method, and check for implied variables. Also, consider the statistics and focus on areas where other students tend to struggle. By doing so, you’ll be well on your way to crushing the AP Physics 1 FRQs. Good luck!
