How to Study Physics: A Practical Guide That Works

The best way to study physics is to do physics: attempt problems before you review notes, explain out loud why each step works, and spread your practice across the week instead of cramming. Reading and rereading feels productive but rarely builds the skill that exams test, which is choosing the right principle for a problem you have never seen. This guide shows how to build that skill, with methods taken from university learning centers and published physics education research.

TL;DR

• Attempt problems first, then check notes. Struggling and getting things wrong is part of how recall gets stronger.

• Start every problem by naming the physical principle involved, not by hunting for a formula to plug into.

• Mix topics in practice sessions and spread them over several days. It feels harder, and it works better.

• When you are stuck, give a problem 10 to 15 minutes of honest effort, then get help and write down what you missed.

• Before an exam, practice under time pressure with only the materials the exam allows.

Why physics feels hard (and what to change)

Recognizing a worked solution is different from solving a new problem on a blank page. If rereading and highlighting are your main study methods, add practice that asks you to choose a principle and explain your own steps.

Stanford’s Center for Teaching and Learning recommends active engagement: review prerequisite ideas, write down questions, take notes in your own words, practice problems, and explain why each step, formula and assumption is appropriate. It also advises connecting concepts and retrying missed problems instead of expecting instant mastery.

That shift, from absorbing to producing, is the one change that matters most. Everything below is a way of putting it into practice.

Before the lecture: read first, then ask

The University of Washington Department of Physics recommends reading the relevant textbook sections before lecture, so you can apply the material in class and raise questions while the topic is live. You do not need to understand everything on the first pass. The goal is to arrive knowing what the new vocabulary is and where you are lost.

Benjamin Crowell of Fullerton College makes a related point in Physics LibreTexts: engage with the questions while you read instead of racing through the text without thinking. A simple way to do this:

1. Read one section, then close the book.

2. Write the main idea in one or two sentences in your own words.

3. Write one question the section did not answer.

4. Bring that question to lecture, office hours or a tutor.

Solve problems with a repeatable routine

Physics problems feel overwhelming when you start with the equations. A routine takes the pressure off, because you always know the next move.

Stanford’s physics study tips suggest this sequence: identify what the problem asks, list the given information, determine intermediate quantities, plan your equations and steps, and write every step so errors can be traced.

David Harrison, writing in Physics LibreTexts, adds a modeling frame to it. In his problem-solving sequence you form a model, visualize it, guess the answer, translate the model into equations and solve, then assess whether the result is reasonable by checking units, assumptions and special cases.

Put together, a full pass looks like this:

The guess in step 4 and the check in step 6 are what separate students who catch their own mistakes from those who find out on the exam.

Start with the principle, not the formula

The University of Washington advises beginning a problem by identifying the physical principles and concepts involved rather than memorizing solution steps, because conceptual recognition transfers better to new problems. A memorized procedure breaks the moment the exam changes the setup. A principle such as conservation of energy or Newton’s second law applies in many setups.

Try this habit on every problem you do: before writing any equation, finish the sentence “This problem is about ___, because ___.” If you cannot, that is the gap to fix, and it is more valuable to find it on homework than on test day.

Six study methods backed by research

Carnegie Mellon’s Open Learning Initiative offers a free Student Cognition Toolbox for physics built around six research-informed strategies: practice quizzing, self-explanation, elaborative interrogation, worked examples, spaced practice and interleaved practice. Here is what each looks like in an ordinary week.

Practice quizzing (retrieval)

The University of North Carolina Learning Center reports that attempting a practice problem before rereading your notes can improve learning, even when the attempt includes mistakes, because retrieval practice strengthens recall. A 2021 Physics Education Research study adds that retrieval practice strengthens physics memories, makes them easier to access and transfer, and can reduce floundering during problem solving by emphasizing when principles apply.

In practice: close your notes, pick a problem, and attempt it cold. Then open the notes and mark what you missed.

Self-explanation

The same 2021 study describes self-explanation as identifying principles, conditions of application and reasons for how equations are set up when you study worked examples. This builds abstract problem-solving rules that help on conceptually challenging problems.

In practice: when you read a solved example, stop at each line and say why that step is allowed. Why is momentum conserved here and not energy? Why can you ignore friction?

Elaborative interrogation and worked examples

Elaborative interrogation just means asking “why?” and “why this and not that?” until the answer is something you could teach. Worked examples give you a model of expert reasoning to study before you try similar problems alone. Use them early on a new topic, then fade them out as you gain confidence.

Spaced practice

Harrison notes that physics is learned better through steady weekly work than last-minute cramming, because understanding a small number of powerful concepts takes time. Three 40-minute sessions on different days beat one two-hour block on Sunday night.

Interleaved practice

Interleaving means mixing problem types in one session instead of doing ten of the same kind in a row. In one undergraduate physics course, a 2021 study in npj Science of Learning found that students assigned interleaved homework scored higher on two surprise tests of novel problems. The relative median-score differences were 50% on one test and 125% on the other. The study found no statistically significant advantage on subsequent midterms. These are results from that study, not expected gains for every student or results from using BoredProf.

There is a catch you should expect. The same study found students perceived interleaving as harder and wrongly believed they were learning less. If mixed practice feels messy, that is normal and not a sign it is failing.

Fix your math gaps early

Physics problems often fail at the algebra, not the physics. Crowell advises students to identify specific mathematical weaknesses and get help with them, and not to ignore foundational issues such as scientific notation or vector addition.

Keep a short “math errors” list. Each time you lose points to a sign error, a unit conversion or a trigonometry slip, write it down. After two weeks you will see a pattern, and that pattern tells you what to review.

What to do when you are stuck on homework

Getting stuck is normal. What you do next decides whether it teaches you anything.

The UNC Learning Center suggests spending about 10 to 15 minutes parsing the problem and attempting a solution from memory before you consult any resource. Write down possible concepts and strategies, then compare what you knew with what you missed. UNC also recommends recording which parts were intuitive, which you missed, why the errors happened, and how you will recognize the right strategy next time.

A workable routine:

1. Attempt for 10 to 15 minutes. Write what you tried, even if it is wrong.

2. Look for one hint, not the whole answer. A single step from a worked example, a tutor or a classmate.

3. Redo the problem from scratch without looking.

4. Log the lesson in one line: “Forgot that tension differs on each side of a pulley with mass.”

Do not let confusion pile up. The University of Washington notes that physics foundations support later topics, and it advises students to contact an instructor or teaching assistant when they are confused.

Build a routine that fits a busy week

You do not need hours every day. You need a plan you will keep. The University of Washington suggests making a weekly schedule for assignment deadlines and planned work, and setting aside study time relative to office hours and TA sessions, so you arrive with questions.

A sample week for a student with one physics course:

That is 160 minutes, or two hours and 40 minutes. Adjust it to your course load, but keep the pattern: pre-read, attempt, fix, mix.

How to study for a physics exam

The UNC Learning Center recommends a specific approach: identify each unit’s learning goals, group practice problems by goal, and solve one from each group under time pressure. Then try related problems with altered scenarios or combined concepts, compare your homework with exam-style problems, and judge whether you can solve them efficiently.

The University of Washington adds that practice is required even when textbook explanations seem clear, and it recommends practicing alone with only the notes or equation sheet your exam permits.

A one-week countdown:

• Days 7 to 5: List the learning goals for each unit. Mark the ones you cannot yet explain.

• Days 5 to 3: Attempt mixed problems cold. Log every miss with its cause.

• Days 3 to 2: Take a timed practice set with your permitted sheet only.

• Day 1: Light review of your error log and equation sheet. Sleep.

Choosing free resources for self-study

If you are teaching yourself, or your course materials are thin, free university resources are a good place to start. MIT OpenCourseWare offers free lecture notes, exams and videos with no registration required, which gives you real problem sets and exams to practice with. PhET Interactive Simulations from the University of Colorado Boulder are free, research-based simulations that animate what is invisible to the eye, such as fields and circuits, and let you change variables to see what happens.

When choosing a resource, ask three questions:

• Does it make you attempt problems, or only watch someone else solve them?

• Does it match the level and notation of your own course?

• Does it explain why each step is valid?

A video you only watch is a good supplement and a poor substitute for practice. Pair every hour of watching with at least as much time solving.

Apply these methods to your own course

BoredProf starts with the student’s own course materials. Its website describes spoken explanations, step-by-step whiteboard drawings, follow-up questions and visual feedback on working. Use those explanations alongside your lecture notes, check each step, and then attempt a similar problem independently. BoredProf is accepting waitlist sign-ups and opening access course by course.

FAQ

What’s the best way to study for a physics exam?

Group practice problems by unit learning goal, solve one from each group under time pressure, and then try variations that change the scenario or combine concepts. Practice alone with only the notes or equation sheet your exam allows. Review your error log in the last day instead of learning new material.

How many hours a week should I study physics?

There is no single research-backed number, and it depends on your course load. What the sources do agree on is the pattern: steady weekly work beats last-minute cramming. A few shorter sessions on different days, including a mixed-topic review, is a sound starting point you can scale up before exams.

What should I do when I cannot solve a physics homework problem?

Spend 10 to 15 minutes attempting it and writing down possible concepts before you look anything up. Then get a single hint, redo the problem from scratch, and log what you missed and why. If you are still confused after that, contact your instructor or teaching assistant instead of letting the gap grow.

Is memorizing formulas enough to pass physics?

No. The University of Washington advises identifying the principles involved rather than memorizing solution steps, because conceptual recognition transfers to new problems. Learn what each formula says, when it applies, and what assumptions it needs. Your equation sheet, if you get one, can hold the formulas while you practice choosing the right one.
