JEE Main 2026 Physics Important Topics for 21st January: The Joint Entrance Examination (JEE) 2026 is scheduled to commence on January 21, 2026. Appearing candidates can go through the detailed analysis of JEE Main 2026 Physics Important Topics for 21st January. This is based on the previous year’s shift-wise exam analysis. The Physics section has consistently been on the moderate to difficult level. In the year 2025 and 2024 Physics papers were among the toughest papers with tricky and lengthy questions, especially.
While 2024 was heavily formula-based, JEE Main 2025 Physics questions were more conceptual and tricky, particularly in the later shifts. After analysing the Physics section of JEE Main 2025 and 2024 (Session 1) it shows that the authorities focused on the Modern Physics and Electromagnetism section. Aspirants looking to maximise their score in the shortest time can take JEE Main 2026 Physics Important Topics for 21st January that are mostly asked and can help them achieve a score of 80+.
JEE Main 2026 Physics Important Topics for 21st January
Considering historical trends, the JEE Main Physics section continues to be a mix of high-yield conceptual topics and formula-based numericals. The question paper seems to be a mix of Mechanics, Electrodynamics, and Modern Physics. Based on such analysis, here’s the list of JEE Main 2026 Physics Important Topics for 21st January, along with the expected number of questions per shift.
| JEE Main 2026 Physics Important Topics for 21st January | Expected Questions Per Shift |
Electrostatics and Capacitancy | 2-3 |
| Modern Physics | 3-4 |
Units, Dimensions and Errors, Basic Maths | 1-2 |
| Ray Optics | 1-2 |
| Magnetic Effect Of Current and Magnetism | 1-2 |
| Gravitation | 1-2 |
| Fluid Mechanics | 1-2 |
| Thermodynamics | 2-3 |
| Current Electricity | 1-2 |
| Work Energy Power | 1-2 |
Electromagnetism (EMI/AC/Magnetism) usually accounts for 25–30% of the entire Physics paper, and there are 2–3 direct questions per shift from modern physics. Also, most of the numerical-based questions in Physics are from Mechanics and Thermodynamics. Candidates who are strong in formulas can prioritize these chapters.
