An AI chatbot can solve most textbook physics problems quickly. That is the risk: if it does the thinking during practice, you walk into the exam without having practised. The routine below keeps the AI as the tutor and you as the one solving.
Does using AI for physics homework actually help you learn?
It depends on how you use it. In a 2025 field experiment published in PNAS, researchers gave nearly a thousand high school maths students access to GPT-4 tutors. One was a plain ChatGPT-style interface. The other was prompted to safeguard learning by guiding students rather than giving answers.
While students had access, their grades on practice problems rose 48% with the plain version and 127% with the guided tutor, according to the PNAS paper. Once access was taken away, students who had used the plain version scored 17% lower than students who never had AI at all. The authors found that students had used it as a "crutch", and that the guided tutor's safeguards largely mitigated the harm.
Physics has similar evidence. In a randomised trial in an introductory physics course at Harvard, 194 students learned significantly more in less time from a custom AI tutor than from an in-class active-learning lesson. The tutor scaffolded problems one part at a time, according to the full paper on PubMed Central.
What does a weekly physics routine with an AI tutor look like?
Pick one chapter, say Current Electricity, and give it a week.
Monday: concept first. Ask the AI to explain the idea, then explain it back in your own words. Ask it to point out what you got wrong. No problems yet.
Tuesday: guided problems. Do three or four textbook problems. You write every step; the AI only gives hints when you are stuck.
Wednesday: harder problems, fewer hints. Mix in a previous-year question. Allow yourself one hint per problem.
Thursday: self-test. Ask the AI for five fresh questions and no answers. Solve them on paper with a timer, then get it to check your working.
Saturday: mixed review. A few questions from last week's chapter and a few from this week's, before you start anything new.
The gaps are deliberate. A review of ten study techniques in Psychological Science in the Public Interest rated practice testing and spreading practice over time as the two high-utility techniques, and rereading as low utility. In a classic testing-effect study, students who tested themselves remembered more after two days and after one week than students who restudied, even though restudying made them feel more confident.
If you don't know where to begin a chapter, Fermi's AI tutor can work out what you already know and build a plan for the session. That way you start with a clear next step, not a blank page.
What does a guided physics problem with AI sound like?
Problem: a ball is thrown straight up at 20 m/s. How high does it go? (Take g = 10 m/s².)
Don't type "solve this". Type: "Don't give me the answer. Ask me one question at a time."
AI: What is the ball's velocity at the highest point?
You: Zero.
AI: Which equation links u, v, a and s without time?
You: v² = u² + 2as. So 0 = 400 − 20s, and s = 20 m.
AI: Good. Now, how long does it take to get there?
How do you stop yourself copying AI answers?
Set rules you can see.
Write your attempt on paper before you open the chat.
Ask for a hint, not a solution. If you do see a full solution, close it and redo the problem from scratch the next day.
When an answer is wrong, ask "which step is wrong?" instead of "what is the answer?"
End each session by explaining the method out loud, briefly, without notes.
When your mistake is the method itself, the Fermi Problem Library has a step-by-step solver that explains the reasoning rather than printing an answer. Use it after your own attempt, not before. If the gap is the idea underneath, the Fermi Concept Library has a lesson for each concept in physics.

How can parents help without hovering?
You don't need to know physics. On Thursday, ask your child to teach you one self-test problem. If they can explain why each step works, the week went well. If they can only repeat the AI's words, go back to Monday's step.
If study stress starts affecting sleep or mood, talk to a school counsellor or call Tele MANAS on 14416.
Start with one chapter this week, and keep the paper attempt first.
