Core topics such as Mechanics, Electrodynamics, and Modern Physics will remain unchanged. However, less relevant topics such as the potentiometer, applications of transistors, Doppler effect in sound, and certain parts of Thermodynamics and Oscillations have been removed.

The syllabus reduction provides students with the opportunity to focus on chapters of greater importance. It also helps in strengthening conceptual understanding and streamlining exam preparation.

JEE Main Physics Syllabus 2026: Complete List of Removed Topics

The syllabus reduction has affected several units of Physics from both Class 11 and Class 12. The removed topics were mostly considered less relevant to the fundamental engineering concepts tested in JEE Main.

Here's the complete list of deleted topics:

Unit	Deleted Topics/Chapters
Physics and Measurement	Physics, technology, and society; Accuracy and precision of measuring instruments
Kinematics	Zero vector
Properties of Solids and Liquids	Reynolds number; Newton's law of cooling
Thermodynamics	Carnot engine and its efficiency
Oscillations and Waves	Free, forced, and damped oscillations; Resonance; Doppler Effect in sound
Current Electricity	Resistance of different materials; Colour code for resistors; Potentiometer (principle and applications)
Magnetic Effects of Current	Cyclotron; Magnetic susceptibility and permeability; Hysteresis; Electromagnets and permanent magnets
Electromagnetic Induction	Quality factor
Optics	Resolving power of microscopes and astronomical telescopes
Atoms and Nuclei	Isotopes, isobars, and isotones; Radioactivity (alpha, beta, and gamma particles/rays and their properties); Radioactive decay law
Electronic Devices	Junction transistor; Transistor action; Characteristics of a transistor; Transistor as an amplifier and oscillator; Switch

How Does This Affect JEE Main 2026 Physics Preparation?

The removal of topics like Potentiometer and Transistor applications brings good news for students. You no longer need to memorise complex circuit diagrams or specific characteristics of these devices.

This change allows you to focus more deeply on core areas. These include:

Mechanics
Electrodynamics
Modern Physics

Which Chapters Are Deleted from JEE Main Physics 2026?

Entire chapters are rarely removed from the syllabus. However, specific sections within units have been significantly reduced.

For example, the Communication Systems unit has been completely removed in recent years. This was once a regular part of the JEE Main Physics syllabus. This change simplifies the Electronic Devices and Modern Physics segments of the exam.

Why Did NTA Reduce JEE Main Physics Syllabus?

The NTA and the Ministry of Education initiated the syllabus reduction for specific reasons. The main goal was to match the rationalised NCERT textbooks.

This ensures that students from various boards across India have a level playing field. Students aren't burdened with topics that are no longer part of their school curriculum.

JEE Main 2026 Physics Preparation Strategy After Syllabus Reduction

With the reduced JEE Main Physics syllabus 2026, a smart preparation strategy becomes essential. Here's how you can adjust your study plan effectively:

Analyse the Weightage: With fewer topics, the importance of remaining chapters increases. Focus more on Current Electricity (without Potentiometer) and Magnetic Effects (without Cyclotron).

Focus on Concepts: Since the number of topics is reduced, NTA may increase the conceptual depth of questions. Build strong fundamentals instead of surface-level knowledge.

Practice Updated Mock Tests: Use mock tests that reflect the reduced JEE Main Physics syllabus 2026. This gives you a realistic feel for the actual exam pattern.

Key Takeaways

JEE Main 2026 Physics syllabus has been reduced significantly
Topics from 11 units have been deleted
Core areas like Mechanics and Electrodynamics remain intact
Syllabus reduction aligns with rationalised NCERT textbooks
Students should focus on high-weightage chapters for better scores
