⚛️ JEE Physics

Chapters

1. Units, Dimensions and Error Analysis
   This is the least glamorous chapter in Physics and reliably one of the most profitable: the exam asks one or two questions from it almost every year, they are usually…
2. Kinematics — Straight Line, Plane Motion, Projectiles and Relative Velocity
   Kinematics is where most students first meet the difference between knowing a formula and knowing when it applies. The three equations of motion are memorised in a day;…
3. Laws of Motion, Friction and Circular Dynamics
   Almost every mechanics problem you will ever meet is solved by the same three steps: isolate one body, draw every force on it, and write ΣF = ma along a chosen…
4. Work, Energy, Power, Centre of Mass and Collisions
   This chapter gives you the two most powerful shortcuts in mechanics. Energy conservation lets you connect a starting state to a finishing state without ever touching the…
5. Rotational Motion — Moment of Inertia, Torque and Rolling
   Rotation is where students who have coped with mechanics by memorising formulae come unstuck, and where students who understood the analogy sail through. Every…
6. Gravitation — Fields, Potential, Orbits and Escape
   Gravitation is a small chapter that reliably yields one or two questions, and it is unusually forgiving because almost everything follows from a single inverse-square…
7. Oscillations and Waves — SHM, Superposition, Beats and Doppler
   One condition defines this entire chapter: a restoring force proportional to displacement and directed opposite to it, F = −kx. Everything else — the sinusoidal motion,…
8. Thermal Physics — Kinetic Theory, the Laws of Thermodynamics and Heat Engines
   Thermodynamics is the chapter where sign conventions decide your marks. The physics is a single equation, ΔU = Q − W, and almost every wrong answer in the topic comes…
9. Electrostatics — Fields, Gauss's Law, Potential and Capacitors
   Electrostatics is the largest single block in the physics syllabus and it rewards a specific habit: decide whether the question wants a vector or a scalar before you…
10. Current Electricity, Magnetism and Electromagnetic Induction
    These three topics together supply the largest share of Physics marks in the paper, and they are connected by one thread: a moving charge is a current, a current makes a…
11. Optics — Reflection, Refraction, Lenses and Wave Optics
    Optics splits cleanly into two halves that answer different questions. Ray optics treats light as travelling in straight lines and tells you where an image forms; wave…
12. Modern Physics — Photoelectric Effect, Atoms, Nuclei and Semiconductors
    Modern physics is the highest-yield block in the physics syllabus per hour of study. The formulae are few, the calculations are short, and the questions are largely…
13. Mechanical Properties of Solids and Fluids — Elasticity, Pressure, Flow and Surface Tension
    This chapter looks long because it names many phenomena, but it is generated by a single quantity: force divided by area. Call it stress and you get elasticity; call it…
14. Electromagnetic Waves — Displacement Current, Maxwell’s Synthesis and the Spectrum
    This is a short chapter with an unusually high return: it is almost always one or two straightforward questions, and every one of them comes from a small set of facts.…
