The  NCERT Solutions for Class 11 Physics can be categorized mainly into 4 parts. The first part contains introductory chapters (chapter 1 and 2), the second part is Mechanics (chapter 3 to 8), the third part is Properties of Bulk Matter and Thermodynamics (chapter 9 to 13) and the part 4 is Oscillation and Waves (chapter 14 and 15).

In CBSE board exam point of view, all the chapters of  NCERT Solutions for Class 11 Physics expect the first chapter. The second chapter Units and Measurements will become very simple after studying all the chapters of NCERT Class 11 and 12 Physics Course. Since we will study the dimensional formula in the coming chapters also. In the second chapter certain dimensional formula is mentioned which you will study in your twelfth class. The chapters from 3 to 8 are interconnected and all the chapters are important with high weight for System of Particles and Rotational motion. In NCERT solutions for Class 11 Physics part 2, the chapter thermodynamics and oscillations and Properties of Fluids have a high weight. The following are the list of chapters.

## NCERT Solutions for Class 11 Physics part 1 contains the following 8 chapters:

Chapter-1 Physical World: This is a general chapter. This chapter gives general ideas about the definition of Science, Physics and fundamental forces in nature. This chapter is not important in exam point of view. This is for general awareness. A few inventions and scientific principles are also mentioned in the chapter.

Chapter-2 Units and Measurements: This chapter gives an introduction to fundamental and derived units, errors and measurement of errors, significant figures and dimension, and dimension analysis. The concepts studied here are used throughout the Physics course, mainly the dimensional formula. This is an important chapter for CBSE board exam. You can get one question from this chapter

Chapter-3 Motion in a straight Line: This chapter talks about the position, distance, speed, velocity, acceleration, equations of uniform motion and relative velocity. The concept mentioned here are the basics of mechanics. It is important to understand all the terms mentioned in this chapter. The terms mentioned here will be used in your physics course in many places.

Chapter-4 Motion in Plane: This NCERT Class 11 Physics chapter deals with an introduction to vectors, resolution of vectors, motion in a plane, projectile motion and uniform circular motion. The topic of vectors is important because we will use it in almost all chapters of class eleven and twelfth physics.

Chapter-5 Law of Motion: The Chapter talks about the inertia, Newton's laws of motion, circular motion and how to solve problems in mechanics. It is important to understand the concept of resolution of vectors and free body diagrams. It is necessary to solve a large number of problems to understand the application of Newton's laws of motion. The concept studied here will be used in the coming chapters also.

Chapter-6 Work, Energy and Power: The main content of this chapter are Work-Energy theorem, power, and collisions. Collision is an important topic where you can expect questions. The application of Work-Energy theorem will be used throughout the eleventh and twelfth Physics course.

Chapter-7 System of Particles and Rotational motion: This chapter deals with the rigid body, the centre of mass, the moment of inertia and kinematics and dynamics of rotational motion. In the exam point of view, this is an important chapter. You can expect problems from this chapter. The concept studied in the previous chapters will be used here. It is important to practice more problems in this chapter to understand the concept of this chapter.

Chapter- 8 Gravitation: The chapter introduces the concept of gravitational force, field and energy, and Kepler's law. Another important topic of this NCERT class 11 chapter is Satellite It is better to memorize the formulas and derivations mentioned in the chapter. You will study the similar types of formulas in class 12 Physics unit Electrostatics.

## NCERT Class 11 Physics Part 2- Chapter list

Chapter-9: Mechanical Properties of Solids

Chapter-10: Mechanical Properties of Fluids

Chapter-11: Thermal Properties of Matter

Chapter-12: Thermodynamics

Chapter-13: Kinetic Theory

Chapter-14: Oscillations

Chapter-15: Waves

## NCERT Solutions for Class 11 Physics part 2 contains the following 7 chapters:

Chapter- 9 Mechanical Properties of Solids: The main concept of this chapter are stress, strain and Hooks law. If you understand these three concepts very well it is easy to study this chapter. You may get one question from this chapter for CBSE board exam.

Chapter-10 Mechanical Properties of Fluids: the chapter deals with the concept of pressure, streamline flaw, Bernoulli's principle, viscosity, and surface tension. This chapter is very important in both board exam point of view and competitive exam point of view. While studying always it is better to relate to real life example.

Chapter-11 Thermal Properties of Matter: The chapter deals with the concept of temperature and heat, specific heat, expansion, heat transfer, change of state, calorimetry and Newtons laws of cooling. There are many interesting examples of the application of heat and temperature. It is very important to understand the concept of state change in exam point of view.

Chapter-12 Thermodynamics: This chapter deals with the laws of thermodynamics, reversible and irreversible process, heat engine, refrigerator, and Carnot engine. There are many real-life examples that you can relate to this chapter. The topic of the Carnot engine is very important. It is necessary to understand all the graphs mentioned in the chapter.

Chapter-13 Kinetic Theory: This  NCERT Class 11 Physics chapter deals with an introduction to the kinetic theory of gases and an explanation of some properties using kinetic theory.

Chapter-14 Oscillations: This chapter introduces the concept of periodic and oscillatory motions, simple harmonic motion (SHM), damped and forced oscillations. It is necessary to understand the difference between periodic and oscillatory motion. You can expect more questions from the topic of SHM.

Chapter-15 Waves: This is the last chapter of NCERT Solutions for Class 11 Physics part 2 the main topics coming under this chapter are transverse and longitudinal wave, beats and Doppler effect. Beats and Doppler effect is interesting and important topics. To prepare for the board exam it is necessary to solve all the questions from NCERT exercise of all the chapters.

The first chapter of NCERT Solutions for Class 11 Physics is not important in exam point of view and all other chapters are important for the board exam and competitive exam. All the chapters of Mechanics are interrelated. So it is better to study the chapters in order.
