hello there!

To score good marks in physics you should work on your basics make your concepts strong. You can follow NCERT book for your preparation. Refer previous year questions to understand the level of the questions asked in the exam.

You can check the important chapters of Physics below which carries more weightage in the exam

JEE Main

Capacitance- 6.67%

Current Electricity- 10.00%

Calorimetry & Thermal Expansion- 6.67%

KTG & Thermodynamics- 6.67%

Rigid Body Dynamics- 6.67%

Work, Power & Energy- 6.67%

Modern Physics- 10.00%

hope this helps

goodluck!

Hello Aspirant,

See, the question pattern for jee mains changes frequently almost every year. So I am going to give you a brief idea on what that which topics are easy and can be handle with an ease. And on which chapters you have to stress more.

These topics have been carrying a consistent weightage as per the JEE Main previous year papers.

I have divided the important topics into easy scoring topics and difficult topics.

Easy Topics in JEE Main Physics

  • Electrostatics is a very lengthy but is a easy topic. Mostly three to four questions are asked from this topic every year.
  • Current Electricity is a small topic but is very scoring. Questions from the topic like colour code of resisters, Ohm’s Law, etc. are frequently asked in the JEE Main exam.
  • Electro-magnetic Induction and Alternating Current is also easy topic and is an important topic for JEE Main. One to two questions are asked from these two topics each year.
  • Semiconductor & Electronic Devices, Communication, Units & Dimensions, Measurement of error (Absolute and Relative), Instruments. These are very small and scoring topics. One question is usually asked from each of these topics in JEE Main. So, you should not skip these as they can easily score 16-20 marks.

Difficult Topics as per JEE Main Physics Syllabus

The topics given below are also important topics of JEE Main 2020 in Physics, but require dedicated focus and more time.

  • Mechanics is the most important topic for JEE Main. Most of the questions asked in JEE Main demand conceptual understanding of the chapters of Mechanics. Some of the important topics in mechanics for JEE Main are:
    • Newton’s Law of Motion
    • Bernoulli’s theorem
    • Elasticity
    • Equation of Continuity
    • Kinematics
    • Fluid Mechanics
    • Work, Energy and Power
    • Rigid Body Dynamics
    • Gravitation
    • Law of conservation of momentum (linear/angular)
  • Magnetism is a very important topic for JEE Main. Usually, a good number of questions are asked from this topic in JEE Main.
  • Optics is also a very important topic for JEE Main. You should be thorough in this topic.
  • Modern Physics is the most important topic for JEE Main in Physics. This chapter typically has a questions of 12-16 marks in JEE Main. Most frequently asked topics are as below:
    • X-ray (Continuous wavelength, Characteristic Wavelength)
    • Atomic Structure (Spectrum/Radius)
    • Radioactivity
    • Dual Nature of Matter
    • Photoelectric Effect
    • Nuclear fission
  • You must study Oscillation and Waves topic in detail. Questions related to topics like SHM, sound waves, string, Doppler effect, Wave Optics are surely asked in JEE Main each year.
  • 1-2 questions are asked every year from Thermodynamics , so you should be thorough with it as well.
