This page collects class 11 physics notes for every chapter of the rationalised CBSE Class 11 Physics syllabus — 14 chapters in total, split across two NCERT books: 7 chapters in Physics Part I and 7 in Physics Part II. Scan the directory below and tap the chapter you need; pages that are not published yet are marked coming soon, so nothing misleads you.
Unlike a bare syllabus list, each entry in the directory says what the chapter actually teaches — the concepts it introduces and the skills you will use later — so you can decide which chapter you need before you open it.
Class 11 Physics Notes: Chapter-wise Directory
This directory lists all 14 chapters of the rationalised syllabus — the mechanics and gravitation chapters sit in Physics Part I, while thermal physics, oscillations and waves sit in Part II. Each row names the chapter and what it teaches, with a status badge for pages still being written.

Physics Part I (Chapters 1–7)
- Chapter 1, Units and Measurement — covers SI base and derived units, dimensional analysis, significant figures and error estimation. It sets the units and round-off rules used in every later numerical.
- Chapter 2, Motion in a Straight Line — introduces position, velocity, acceleration and the three kinematic equations for motion along one axis. You will also read position-time and velocity-time graphs here.
- Chapter 3, Motion in a Plane — moves to two dimensions using vectors, relative velocity and projectile motion. The vector algebra you learn here returns throughout mechanics.
- Chapter 4, Laws of Motion — explains Newton’s three laws, inertia, momentum, circular motion and friction. Most applied mechanics problems in the syllabus rest on these laws.
- Chapter 5, Work, Energy and Power — defines work, kinetic and potential energy, the work-energy theorem, power and collisions. Energy methods give you a second route to motion problems without forces.
- Chapter 6, Systems of Particles and Rotational Motion — widens from single particles to centre of mass, torque, angular momentum and moment of inertia. Rigid-body rotation and rolling motion are the main applications.
- Chapter 7, Gravitation — presents Kepler’s laws, Newton’s law of universal gravitation, gravitational potential energy and escape velocity. It ties the mechanics of earlier chapters to orbits and satellites.
Physics Part II (numbered 1–7 in the second book, Chapters 8–14 overall)
- Chapter 8, Mechanical Properties of Solids — studies elasticity through stress, strain, Young’s modulus and Hooke’s law. It explains how solids deform under force and when they break.
- Chapter 9, Mechanical Properties of Fluids — deals with pressure, buoyancy, Bernoulli’s principle, viscosity and surface tension. These ideas cover flows from blood vessels to aircraft wings.
- Chapter 10, Thermal Properties of Matter — explores temperature, thermal expansion, specific heat, calorimetry and the three modes of heat transfer. It sets up the thermodynamics chapter that follows.
- Chapter 11, Thermodynamics — states the first law of thermodynamics (energy conservation) and the second law, then applies them to heat engines, refrigerators and entropy.
- Chapter 12, Kinetic Theory — models a gas as many rapidly moving particles to derive pressure, temperature and the ideal gas equation, linking molecular motion to the gas laws.
- Chapter 13, Oscillations — treats periodic motion through simple harmonic motion, spring-mass and pendulum systems, and energy in oscillating systems. Wave study builds directly on it.
- Chapter 14, Waves — covers travelling and standing waves, superposition, interference and beats, using the oscillatory ideas from the previous chapter.
How to Use These Class 11 Physics Notes
Work through the chapters in the order the syllabus lays them out. Finish the Part I mechanics chapters before moving to Part II thermal physics, oscillations and waves, because the later chapters reuse force, energy and circular motion that the early chapters establish.
The one chapter students wrongly skip is Units and Measurement, because it looks easy. Dimensional analysis and significant figures questions do appear in exams, and the SI units taught there are the language of every later chapter. Give it a proper read even when revision time is short.
Pair each chapter’s notes with the NCERT back exercises at the end of that chapter. The solved examples inside the chapter show the standard method to imitate, and the odd-numbered questions at the end give practice at the same level. From the hub, you can return to the Class 11 CBSE Notes to reach any other subject.
What a Class 11 Physics Notes Page Contains
Each chapter page is built for revision, with everything in one place instead of scattered across a notebook:
- A one-page formula sheet with every equation used in the chapter
- Worked derivations written in plain, original wording you can follow step by step
- Solved examples using fresh numbers rather than the textbook’s figures
- Key definitions, laws and their exceptions flagged for quick scanning
- Common exam mistakes called out so you know what not to repeat
When formulas and solved steps sit side by side, you revise faster and notice gaps sooner. To verify the chapter order and content against the official text, open the NCERT Physics Part I textbook on ncert.nic.in alongside these notes.
Frequently Asked Questions about Class 11 Physics Notes
How many chapters are there in Class 11 Physics?
Fourteen chapters in total, split as seven chapters in NCERT Physics Part I and seven in Part II.
Which chapter should I study first in Class 11 Physics?
Start with Units and Measurement, then follow the Part I order: Motion in a Straight Line, Motion in a Plane, Laws of Motion, Work, Energy and Power, Systems of Particles and Rotational Motion, and Gravitation.
Are these Class 11 Physics notes based on the latest NCERT syllabus?
Yes. The directory follows the rationalised NCERT edition, and an older textbook may number the chapters differently — match by title rather than by number.
Is Units and Measurement important for the Class 11 Physics board exam?
Yes. Dimensional analysis and significant figures are regularly tested, and the SI units the chapter introduces appear in every later chapter.
