JEE Physics Important Topics

JEE Physics Important Topics

Most of the JEE aspirants consider physics as one of their favorite subjects because it not only helps them to develop critical thinking but also helps them to acquire problem-solving skills. It also happens to be a key subject particularly in highly competitive examinations like JEE Mains and Advanced. In JEE exams, the questions asked in physics section are generally based on the conceptual knowledge about the topic. For scoring well, you are required to have a strong conceptual base along with the practical application of concepts.

There are around 20 chapters included in JEE Physics syllabus and out of these, there are certain important topics that must be focused on while preparing for JEE Physics:

1. Mechanics: The questions asked from this unit are either directly based on some mechanical concepts or might require considerable skills in mechanics, which could help you in solving the question. JEE mechanics is all about few fundamental laws like – Newton’s laws of motion, laws of gravitation, laws of conservation of linear and angular momentum. All these laws form a framework in physics and thus it is expected that you should understand all these laws and apply them to practical problems.

Questions from mechanics could be solved easily by the combination of Laws of conservation of energy, Newton’s laws, Equation of continuity, Work energy theorem, Laws of conservation of momentum and Bernoulli’s theorem. These topics have applications in other chapters of Physics too. Therefore, they are probably the most important topics that you need to focus on.

2. Electricity and magnetism: Due to its vastness and the level of difficulty, this unit is very crucial for both JEE Mains and Advanced. Every year lots of questions are asked in JEE from this unit. You don’t have to worry much about physics in JEE if you practice and prepare well for this unit. You can expect lots of questions from capacitance, coulombs law, and its applications.

Don’t get scared of complicated circuit problems and try to understand the fundamentals for reducing complicated electrical circuits into simpler ones. Practice several questions from Kirchhoff’s laws and series-parallel circuit reduction and also don’t ignore the theoretical aspects of the topic. Memorise all the formulas and practice several questions from electrostatics, Motional EMF, and magnetostatics.

3. Fluid mechanics & Thermal physics: Familiarize yourself with the calculations of work, heat, Carnot engine and its efficiency, internal energy and the laws of thermodynamics. Several times in JEE Exams questions from the laws of thermodynamics were mixed with the calorimetry. Practice several numbers of questions from fluid mechanics as well.

4. Oscillation and waves: Every year around 4 to 5 questions are generally asked from this unit. Try to understand certain complex topics like the principle of superposition, reflection & refraction of waves, forced and damped oscillations, resonance, Simple Harmonic Motion, Doppler effects in sound through visualization. It will not only make you understand the concepts easily but will also help you in retaining it for a longer period of time.

5. Optics: This is one of the easiest and highly scoring unit. Practice several numbers of questions from this unit and try to focus more on certain important topics like Interference, Young’s double slit experiment, wavefront, Huygens’ principle, Laws of reflection & refraction, Polarisation, Dispersion of light by the prism, Lens Formula and Magnification.

6. Modern physics: Mostly theoretical questions are asked from this unit. Focus more on understanding the Bohr’s model of atomic structure. Formula-based questions are generally asked from this unit, therefore, memorize all the formulas properly and use them correctly while answering the questions.
