Preparing for JEE Main Physics requires more than just completing the syllabus. Over the years, a clear pattern has emerged in the exam—certain topics and concepts are asked repeatedly across multiple shifts and sessions. Identifying these most repeated topics in JEE Main Physics helps students prioritise their preparation, save time, and maximise scoring potential.
This article provides a detailed analysis of the most frequently repeated topics in JEE Main Physics 2026, based on previous years’ question paper trends. It also includes chapter-wise priority, topic patterns, preparation strategy, and FAQs commonly asked by students.
Note: The analysis is based on past trends and PYQs. Actual question papers may vary, but repetition at the concept level is a well-established pattern in JEE Main.
In JEE Main Physics, “repeated topics” do not imply exact repetition of questions. Instead, repetition happens at the conceptual and application level. A topic is considered “most repeated” if:
Such topics are considered high-return areas, especially for students targeting 85–99 percentile.
Mechanics forms the foundation of Physics and consistently contributes a significant portion of questions in the JEE Main examination. A clear understanding of Mechanics not only helps in scoring direct marks but also strengthens conceptual clarity required for other units of Physics.
In JEE Main Physics, questions from Mechanics are usually based on standard concepts, formula application, and graphical interpretation. Several chapters from this unit are repeatedly asked every year, making them highly important for focused preparation.
Below is a chapter-wise list of the most scoring and frequently asked topics in JEE Main Physics – Mechanics, based on previous year trends.

Electrodynamics combines fundamental principles of electricity and magnetism. In JEE Main Physics, this unit is frequently tested with both conceptual and numerical questions, making it a valuable area for scoring marks.
Electrostatics
Current Electricity
Electromagnetic Induction
Magnetic Effects of Current
Electromagnetic Waves
These topics are often the source of multiple questions in the Physics section and should be practised thoroughly through previous year papers and mock tests.
Modern Physics has a heavy and consistent presence in JEE Main question papers. It consists of theory, application, and numericals, and is relatively easier to score if concepts are clear.
These areas are regularly featured in JEE Main because they offer clear, formula-based questions that are easier for students to attempt quickly and accurately.
Optics covers the behaviour of light and is divided into ray optics and wave optics. JEE Main often includes both conceptual and calculation-oriented questions from this unit.
Optics questions are typically standard in format and appear frequently, making this chapter very important for scoring.
Thermodynamics and the kinetic theory of gases involve heat transfer, work, energy exchange, and motion of particles in gases. These topics are often repeated because of their foundational nature.
Students should practise numerical and conceptual questions from this unit as they regularly contribute to the Physics section.
Oscillations and waves involve both simple harmonic motion concepts and wave phenomena, which are tested often due to their predictable patterns.
These topics help in scoring consistent marks when students understand the underlying mathematics and physical interpretation.
Although small, the Experimental Skills section often includes straightforward questions related to lab instruments, measurements and error analysis.
These questions are usually easier and provide quick scoring opportunities if prepared well.
The chapter-wise weightage of JEE Main Physics provides a clear picture of how questions are distributed across different units of the syllabus. This analysis is derived from previous years’ JEE Main question papers, where a total of 300 Physics questions were considered to identify long-term trends.
Understanding this distribution helps students focus on high-return chapters that consistently contribute a larger share of questions, while also planning selective preparation for low-weightage topics.
| Chapter Name | Total Questions Asked | Approximate Weightage |
| Current Electricity | 32 | 10.67% |
| Electromagnetic Induction & Alternating Current | 25 | 8.33% |
| Properties of Solids and Liquids | 21 | 7.00% |
| Optics | 20 | 6.67% |
| Atoms and Nuclei | 19 | 6.33% |
| Kinematics | 19 | 6.33% |
| Electrostatics | 18 | 6.00% |
| Rotational Motion | 18 | 6.00% |
| Magnetic Effects of Current & Magnetism | 16 | 5.33% |
| Units, Dimensions and Measurement | 15 | 5.00% |
| Laws of Motion | 14 | 4.67% |
| Oscillations and Waves | 14 | 4.67% |
| Dual Nature of Matter and Radiation | 12 | 4.00% |

| Total | 300 | 100% |
Important: The weightage shown above is indicative and based on historical trends. The actual number of questions from each chapter may vary in JEE Main 2026.

Instead of memorising questions, students should focus on patterns.
Understanding these patterns improves speed and confidence.
A structured PYQ approach is highly effective.
Step-by-step method:
This method mirrors how many high-rankers prepare selectively.
Identifying and prioritising the most scoring topics lets students allocate time more efficiently, especially when time is limited. Rather than attempting to complete every topic superficially, focusing on these high-yield areas improves accuracy, confidence, and overall performance in the Physics exam.
This approach works well when paired with:
Preparing based on scoring probability and historical trends gives students an advantage in the competitive JEE Main environment.

Based on previous five-year trends, Current Electricity, Electrostatics, Magnetism, EMI & AC, Optics, and Modern Physics collectively contribute the highest number of questions in JEE Main Physics. These chapters are considered high-priority for preparation due to their consistent presence across sessions.
No. JEE Main does not follow a fixed chapter-wise distribution. The weightage is trend-based and indicative, derived from past year question papers. Actual question distribution may vary from shift to shift and year to year.
High-weightage chapters generally contribute 1–3 questions per paper on average. When combined, top chapters can account for nearly 60–65% of the Physics paper, depending on the session.
Exact questions are rarely repeated. However, concepts, numerical patterns, and standard problem types are frequently reused with different values or framing. This makes previous year questions (PYQs) highly important.
Modern Physics is one of the most scoring units and can contribute 25–30 marks if prepared well. However, relying only on Modern Physics is not recommended. Combining it with Electrodynamics and Optics leads to better overall performance.
Chapters such as Modern Physics, Units and Measurement, Current Electricity, and basic Optics offer a high return for the time invested, as they often include direct or formula-based questions.
Chapter-wise weightage should be used to prioritise study time, not to skip chapters completely. High-weightage chapters should be prepared in detail, while low-weightage topics can be revised selectively, especially during the final phase.
Mechanics as a whole contributes a significant portion, but the weightage is spread across multiple chapters. Kinematics, Laws of Motion, Work–Energy–Power, and Gravitation are more frequently asked compared to advanced rotational mechanics.
Yes. A large portion of JEE Main Physics questions are direct formula-application or standard numerical problems, especially from Electrodynamics, Optics, and Modern Physics.
In the final 30 days, students should:
While long-term trends remain largely consistent, shift-wise variations can affect chapter distribution. Students should aim for balanced preparation with priority-based focus rather than relying on exact percentages.
