Hi Rahul!

Here is a list of important Physics Topics for IIT JEE as per Syllabus Weightage. These 3 are the most basic concepts that you ought to know. You can expect at-least 1 question from these topics:

1. Units and Dimensions (Weightage: 2%)
2. Measurement of Errors (Weightage: 2%)
3. Vectors

These topics are classified as fundamentals in physics. You can expect 1 – 2 questions from this section on an actual JEE Paper.

1. Kinematics  (Weightage: 1%)
2. Newton’s Laws of Motion  (Weightage: 4%)
3. Friction

These 5 topics are important & easy and can help your score high marks very easily in the JEE:

1. Work, Energy and Power  (Weightage: 5%)
2. Electrostatics  (Weightage: 6%)
3. Current Electricity  (Weightage: 7%)
4. Wave Optics  (Weightage: 5%)
5. Ray Optics  (Weightage: 6%)

These 9 topics are absolutely important for JEE. You can expect twisted questions from these sections, so you need to to know your basics well.

You can expect 2 – 3 questions from most of the topics listed below.

1. Centre of Mass, Momentum and Collision – Weightage: 5%
2. Rotational Dynamics – Weightage: 4%
3. Simple Harmonic Motion – Weightage: 5%
4. Fluid Mechanics – Weightage: 2 – 5%. Bernoulli’s principle can be easily twisted to ask some tricky questions.
5. Wave Motion and String Waves – Weightage: 5%
6. Magnetism – Weightage: 6%
7. Heat & Thermodynamics – Weightage: 6%. This is one topic that is very important for both Physics and Chemistry preparation in JEE.
8. Nuclear Physics – Weightage: 5%
9. Modern Physics – Weightage:

You can also watch tutorial videos on Youtube and the likes for getting clearer conceptual understanding.

Expect 3 – 4 questions from the topics below-

1. Circular Motion – Weightage: 1%
2. Gravitation – Weightage: 1%
3. Properties of Matter, Elasticity  – Weightage: 2%
4. Sound Waves
5. Electromagnetic Induction – Weightage: 3%
6. Alternating Current  – Weightage: 1%
7. Heat Transfer
8. Calorimetry
9. Thermal Expansion
10. Thermo Electricity
11. Semiconductors and Electronic Devices – Weightage: 5%
12. Communication Systems – Weightage: 2%

By average Number of questions asked in past JEE Main/Advanced Physics papers:

1. Current Electricity: 8 questions asked on the actual JEE paper each year on an average
2. Electrostatics: 4 questions
3. Optics: 3 questions
4. Heat and Thermodynamics:  2 questions
5. Law of Motion: 2 questions
6. Waves: 2 questions
7. Simple Harmonic Motion: 2 questions

You can expect some more questions (mix and match) from the other topics in the syllabus.

Best of luck!
