Quick answer
JEE Main Physics is 25 questions and 100 marks — 20 MCQ plus 5 numerical — from Class 11 and 12. Mechanics and Electrodynamics dominate, with Modern Physics offering the best marks-per-hour in the section. Unlike NEET Physics, JEE Main also examines Experimental Skills, a small unit that is widely skipped and regularly asked.
Chapter list with weight #
| Area | Chapters | Weight |
|---|---|---|
| Mechanics | Units and Measurements, Kinematics, Laws of Motion, Work Energy Power, Rotational Motion, Gravitation, Properties of Solids and Liquids | Heaviest |
| Electrodynamics | Electrostatics, Current Electricity, Magnetic Effects of Current and Magnetism, EMI and Alternating Currents, Electromagnetic Waves | Heaviest |
| Heat & Thermodynamics | Thermodynamics, Kinetic Theory of Gases | Medium |
| Oscillations & Waves | Oscillations, Waves | Medium |
| Optics | Ray Optics, Wave Optics | Medium |
| Modern Physics | Dual Nature of Matter and Radiation, Atoms and Nuclei | High value |
| Electronic Devices | Semiconductors, Logic Gates | Light |
| Experimental Skills | Vernier callipers, screw gauge, metre bridge, potentiometer, error analysis | Light but always asked |
💡 Tips
- Experimental Skills is free marks for anyone who studies it — a small, closed unit that most candidates skip entirely. Error analysis in particular recurs.
- Modern Physics has the highest marks-per-hour: a small syllabus, formula-driven, always present.
- Mechanics is foundational. Weakness there propagates into rotation, SHM, fluids and gravitation.
- Numerical questions in Physics demand unit discipline. An answer in the wrong unit scores zero and now costs −1.
- Practise with the on-screen calculator, which is slower than you expect for multi-step Physics.
JEE Main Physics syllabus — frequently asked questions
How many questions come from Physics in JEE Main?
Twenty-five questions worth 100 marks — 20 multiple choice and 5 numerical value — carrying exactly the same weight as Chemistry and Mathematics.
Which Physics chapters have the highest weightage in JEE Main?
Mechanics and Electrodynamics are the two heaviest blocks. Modern Physics offers the best return per hour because the syllabus is small and largely formula-driven.
Is Experimental Skills asked in JEE Main?
Yes, regularly, and it is one of the most commonly skipped units. Vernier callipers, screw gauge, metre bridge, potentiometer and error analysis all appear.
Is NCERT enough for JEE Main Physics?
No. NCERT establishes the concepts but its problems are far below JEE difficulty. A dedicated problem book is essential for this section.
What is the difference between JEE Main and NEET Physics?
The chapter lists overlap heavily, but JEE Main includes Experimental Skills and pitches problems at a higher difficulty, with numerical-value answers rather than only multiple choice.
