Physics, one free-body diagram at a time
Most physics mistakes happen before the first equation: the wrong forces, the wrong frame, a unit that quietly changed. SparkMentor slows down at exactly those points and asks you to set the problem up before it solves anything.
What you can bring
Type it, paste it or snap a photo. The tutor starts from where you are, including from your own wrong attempt.
- Mechanics problems with blocks, pulleys and inclines
- Circuits you can't reduce to an equivalent resistance
- Projectile and circular-motion questions
- A derivation from class you want to rebuild yourself
- Numericals where your answer is off by a power of ten
- Concept questions: "why doesn't the normal force do work?"
How a session goes
SparkMentor teaches the way a good private tutor does: it explains, then hands the next step back to you.
Student: A 2 kg block slides down a 30° incline with friction. I don't know where to start.
SparkMentor: Start with the forces on the block. Which ones can you name, and which way does each point?
Student: Gravity down, normal force away from the slope, friction up the slope.
SparkMentor: Good. Now tilt your axes along the slope. Which part of gravity pulls the block down the incline?
Want to see it? The tutor can draw the free-body diagram that matches its explanation, labelled the same way.
01
Set up before you solve
The tutor asks for the forces, the frame and the knowns first, because that's where marks are lost. The algebra comes after.
02
Diagrams on request
Free-body diagrams, ray diagrams, circuits and field lines can be drawn to match the explanation, so the picture and the words agree.
03
Units and sanity checks
Answers get a units check and a does-this-make-sense check: is the speed faster than sound, did the mass cancel when it should have?
04
Talk it through out loud
On Standard and Pro you can call the voice tutor and reason through a problem the way you would with a teacher at the board.

Features you'll use for physics
Each one has its own page: how it works, what it costs.
- Step-by-step tutoringPaste or type any math, physics or chemistry problem and SparkMentor works through it step by step, asking you for the next move so the method sticks.
- Snap a problemTake a photo of a worksheet or textbook page and SparkMentor reads the problem and tutors you through it step by step, instead of just printing an answer.
- Voice tutorTalk to a live AI tutor that listens, asks questions back and explains on the spot. Voice tutoring on SparkMentor Standard and Pro, with video calls on Pro.
- Exam study plansA day-by-day study plan for JEE, NEET, CUET, CBSE, ICSE, ISC and state boards, built from the official syllabus and sized to the minutes you have each day.
- Mistake trackerSparkMentor logs every correction against the concept behind it, then builds quizzes and review from your weak spots, so practice goes where it counts.
- Knowledge treesSparkMentor's knowledge trees show any topic as a map of connected ideas and highlight what you haven't covered yet, so you always know what to learn next.
- AI illustrationsWhen a picture helps, SparkMentor offers a diagram, graph or figure drawn for that exact explanation: a function's shape, a cell, a circuit. Only when you tap.

Questions students ask
Can the AI physics tutor draw diagrams?
Yes. It can draw free-body, ray and circuit diagrams and graphs that match its explanation. It offers an illustration when one would help and draws it only when you tap (40 credits each, refunded if it fails).
Does it help with numericals or only theory?
Both. It works through numericals step by step, checks units and orders of magnitude, and explains the concept behind each step so the next numerical is easier.
Is it useful for JEE and NEET physics?
Yes. Its exam plans follow the official JEE Main, JEE Advanced and NEET syllabi chapter by chapter, and practice quizzes target the chapters where you make the most mistakes.
Can I talk to it instead of typing?
Yes, on Standard and Pro: the voice tutor listens, asks questions back and explains on the spot. Standard includes 30 voice minutes a month and Pro 60.
