Every NCERT chapter of Class 11 Physics, with step-by-step solved problems exactly in the board pattern. Each chapter has its own page carrying the complete set of NCERT exercise questions in the official numbering — pick the chapter below and work through it end to end.
Where can I find Class 11 Physics NCERT solutions chapter-wise?
Right here — all 14 NCERT chapters have their own solution page with every exercise question solved step by step, in the official NCERT numbering. Use the chapter list below to open the chapter you need.
All 14 Chapters
Each chapter below links to its own solution page. Every page opens with the key idea, then works through the complete set of NCERT exercise questions in the official numbering — the step where the marks are won or lost.
How to Use These NCERT Solutions
Open one chapter at a time and follow each line of working with a pencil before checking your own attempt. The solved problems are written in the order the CBSE marking scheme awards method marks: state the formula, substitute values with their SI units, simplify, then box the answer.

How this chapter is asked
High-yield question patterns observed across CBSE boards, JEE Main & Advanced, and NEET.
- 1 m = 100 cm and 1 kg = 1000 g — converting units before substitution is where most numeric slips happen.
- Average speed is total distance ÷ total time, never the mean of the speeds unless the times are equal.
- In projectile motion the horizontal motion has constant velocity and the vertical motion constant acceleration g.
- Static friction always balances the applied force up to its maximum μₛN.
- The normal force on a body in a lift is m(g ± a) — plus when accelerating up, minus when accelerating down.
- The work–energy theorem W = ΔK is often the shortest route to stopping-distance problems.
- v_e = √(2GM/R) = √(2gR) ≈ 11.2 km s⁻¹ for the Earth — escape speed is independent of the mass of the escaping body.
- In calorimetry, heat lost by the hotter body equals heat gained by the cooler one.
- Isothermal processes keep ΔU = 0 for an ideal gas; adiabatic processes keep ΔQ = 0.
- Beats occur at the difference of the two frequencies; a string fixed at both ends gives all harmonics, a closed pipe only odd ones.
FAQ
Frequently asked questions
Which is the best order to practise Class 11 Physics NCERT solutions?
Follow the NCERT chapter order: Units and Measurements, Motion in a Straight Line, Motion in a Plane, Laws of Motion, Work Energy and Power, System of Particles and Rotational Motion, Gravitation, Mechanical Properties of Solids, Mechanical Properties of Fluids, Thermal Properties of Matter, Thermodynamics, Kinetic Theory, Oscillations and Waves — the same order used on this page. It mirrors how each concept builds on the previous chapter.
Does this page have every NCERT question, or do I open a separate page per chapter?
Each of the 14 chapters has its own solution page linked from the list above. Opening a chapter gives you the complete set of that chapter's NCERT exercise questions, solved step by step in the official numbering, so you can work through one chapter without scrolling past the rest.
How do I score full marks in Class 11 Physics board solutions?
Write every method step — state the law or formula, convert units to SI, substitute values, simplify, and box the final answer with its unit. The CBSE marking scheme awards method marks even when the final number is wrong.
Are these NCERT solutions enough for JEE Main and NEET preparation?
NCERT exercises build the fundamentals — kinematics, laws of motion, gravitation, thermodynamics and waves — that JEE Main and NEET test heavily. Use these solved problems to master the standard methods, then practise JEE/NEET-level numericals for speed.
Which Class 11 physics chapters carry the most board marks?
Mechanics dominates: units and measurements, laws of motion, work energy and power, rotational motion and gravitation together form the largest share of the Class 11 board weightage, and the same topics anchor the Class 11 section of JEE and NEET.
