Physics
Physics appears in two guises. In general awareness papers it is asked as school-level facts — which mirror is used in a headlight, why a swimming pool looks shallower than it is. In JEE, NEET and engineering entrance papers it is asked as problems, and the same concepts have to be usable rather than merely known.
These topics are written to serve both. The concept is stated plainly enough for a general studies candidate, and the formula sheet and worked examples go far enough for an entrance paper.

3 topics written
Read these in order
Each topic is a complete lesson — concepts, formula tables, worked examples and practice questions with explanations.
Weighting
Where Physics marks actually sit
A syllabus lists topics with equal visual weight, and no paper treats them that way. The table below collects what each Physics lesson records about the exams that examine it, so the reading order on this page can be checked against the exams you are actually sitting.
Counts are ranges observed across cycles rather than promises. The notification for your cycle is what fixes the paper, and a topic can move.
| Topic | Examined most in | Typical volume | Lesson |
|---|---|---|---|
| Mechanics | JEE Main / Advanced; NEET Physics; SSC CGL / CHSL Tier 1 | 25–30% of the physics paper | 24 min · 16 questions |
| Heat, Light & Sound | JEE Main / Advanced; NEET Physics; SSC CGL / CHSL Tier 1 | 20–25% of the physics paper | 25 min · 16 questions |
| Electricity & Magnetism | JEE Main / Advanced; NEET Physics; SSC CGL / CHSL Tier 1 | 25–30% of the physics paper | 25 min · 16 questions |
How to use the table rather than read it
Find the rows naming the exam you are preparing for, and study those first regardless of where they sit in the reading order above — the order on this page is pedagogical, built so each lesson can rest on the one before it, and it is not a priority list. Where a topic you are weak at also carries the highest volume in your paper, that row is the whole of your next fortnight.
Method
How to study physics
Physics is learned by solving, not by reading. A worked solution you have read produces recognition; a problem you have struggled through produces capability, and only the second survives an exam.
- Attempt every problem for a genuine stretch before consulting a solution. The struggle is the mechanism. Reading the solution first replaces learning with recognition.
- When you do read a solution, close it and reproduce the argument. If you cannot, you have not learned it yet.
- Build mechanics first. Kinematics, laws of motion, work and energy, rotational motion. Everything later assumes them, and gaps here compound.
- Keep an error log classified by cause. Concept gap, algebraic slip, misread question, unit error. Four causes with four different remedies.
- Derive rather than memorise where you can. A formula you can rebuild is one you will not misremember under pressure.
On units and dimensions
A dimensional check takes ten seconds and catches a surprising proportion of algebraic errors before they become wrong answers. It is the cheapest verification available in any physics paper, and almost nobody uses it systematically.
Questions
Physics — FAQs
How deep does physics go in competitive exams?
It depends entirely on the paper. In general studies papers physics appears as applied everyday phenomena at school level. In engineering and medical entrance tests it is examined at the depth of the senior-secondary syllabus, with numerical problem-solving under time. These are different subjects in practice, and preparing for one does not prepare you for the other.
Should I focus on numericals or on concepts?
Concepts first, then numericals in volume — but the ratio depends on your paper. Where physics is examined as applied general knowledge, numerical practice is nearly worthless. Where it is examined in an entrance test, numerical speed is most of the score, and the way to build it is a large number of solved problems rather than more reading.
Which topics are examined most consistently?
Mechanics, because everything else builds on it, and the areas with everyday applications — heat, light, sound, electricity and magnetism — because they generate the applied questions general papers favour. The lesson table above records what each topic carries for the exams that set it.
How do I stop making unit and sign errors?
By writing units at every line of working rather than at the answer, and by redoing wrong questions with that discipline instead of just reading the correct solution. A large share of lost marks in physics are conversions and signs rather than concepts, and the error rate falls quickly once the habit is in place.
Read the concept, then test it the same day
Every topic ends with practice questions, and a full mock is the fastest way to find out which ones actually stuck.
