NCERT Solutions for Class 11 Physics

Class 11 Physics NCERT solutions

Physics is one of the core subjects for anyone who chooses to engineer. It is important to build your basics and have a strong foundation before you go for engineering. The NCERT solutions for class 11 physics given in this article is updated to the latest syllabus. Below we are providing an overview of each chapter that is available in the NCERT textbook for physics.

Chapter 1  Physics World

This first chapter can help you build a good foundation in physics for class 11 and class 12. There are different topics in this chapter like nuclear force, gravitational force, electromagnetic force, etc. This chapter also explains the basic laws in physics that govern the natural phenomenon. There are different concepts from scientists like Faraday, Ampere, Newton, etc which is explained in this chapter.

Chapter 2 Units and Measurement

This is a basic chapter that clears your doubts about units, derived units, base units, a system of units, and much more. This chapter will explain to you how is the international system of units decided and what is the need for it. Along with this, various methods like parallax angle, parallax method, will also be explained for measuring the length.

Chapter 3 Motion in a Straight Line

This chapter introduces the students to the world of kinematics. We have already learned about the fundamental properties of motion in earlier standards. This chapter will help you learn about rectilinear motion along with its measurement in technical and detailed vision. Furthermore, students will also learn about the reference point, and the frame of reference, the magnitude of displacement, path length, instantaneous velocity, relative velocity, retardation, acceleration, etc.

Chapter 4 Motion in a Plane

This chapter you will learn about measuring motion in a plane as well as vector and scalar quantities. You will also get to learn about diagrammatic representation of derivative laws for the addition of vector and scalar quantities. There are topics like displacement and position vector, equality of vectors, vector multiplication by real numbers, the addition of vectors through analytical methods are the topics that will be discussed in this chapter.

Chapter 5 Law of Motion

As far as this chapter is concerned, students will learn about moving bodies and the factors that act on these bodies. Along with this, you will learn about the direction of these moving bodies and their corresponding motion, the gravitational effect on these bodies, etc. Motion is a very ancient topic on which great scientists like Newton, Aristotle, and Galileo have studied. This will also be discussed in this chapter.

Chapter 6 Work, Energy, and Power

There are many basic terms of power, work, and energy that you have studied in earlier standards. But in this chapter, you will study about the relations of all these quantities. You will also have a chance to understand the scalar products and there are distributive laws taught in this chapter. This all forms the fundamentals for understanding in this chapter.

Chapter 7 System of Particles and Rotational Motion

There are mathematical and theoretical concepts explained in this chapter related to rotational motion. These concepts are explained in a very comprehensive manner so that students can have a better understanding of these topics.

Chapter 8 Gravitation

We all know that the objects get attracted to the earth. Thus, everyone is aware of the concepts in gravity and its effects and how it was discovered. However, in class 11 physics, this topic takes you in depths of the concepts related to gravitation. Furthermore, you will get a good grip on the technical basis for gravitation, Kepler’s laws, gravitational law, etc. There are other topics also like Gravitational acceleration, gravity due to earth, gravitational constant, earth satellites potential energy in gravitation, etc that are discussed in this chapter.

Chapter 9 Mechanical Properties of Solids

In this chapter, you will study the physical properties of solids like elasticity, plasticity, and many other things. This chapter goes in depth to reach fundamental concepts like tensile stress, compressive stress, tangential stress, tensile stress, volume strain, etc. This chapter helps in building the foundation of various properties in solids.

Chapter 10 Mechanical Properties of Fluids

This chapter will introduce you to some physical properties like gases and liquids. What common characteristics are between gases and liquids? How does fluid differ from solids? The difference in solids with liquids and gases are some questions that will be answered using this chapter. External forces like pressure and tension and its effects on fluids using mathematical expressions are some of the topics you will understand in this chapter.

Chapter 11 Thermal Properties of Matter

This chapter will teach you the exact meaning of heat and how this heat is measured. There are various topics related to heat flow that will be discussed in this chapter. Some of the interesting daily life phenomena like why the wind reverses its direction near a sea beach or why the blacksmiths healthier iron rings before they fit a rim on the wooden wheel will be explained through this chapter. You will also learn why the temperature does not change when the water boils even though it goes through a great of heat change in the process in this chapter.

Chapter 12 Thermodynamics

Thermodynamics usually deals with the ideas related to the temperature and heat as well as interconversion of heat and other forms of energy. This is considered as a macroscopic science. Furthermore, it deals with the bulk systems and often it does not include the molecular constitution of the matters.

Chapter 13 Kinetic Energy

This chapter will help you in understanding the favor of gases along with fast-moving molecules and atoms. Since the 19th century, Kinetic energy is being studied by some of the great scientists like Maxwell, Newton, Boyle, and many more. This and all is explained in this chapter of kinetic theory.

Chapter 14 Oscillations

This chapter further dwells into projectile motion, rectilinear motion, and other similar motions that you have studied in earlier chapters. The study of oscillations is considered as very basic in physics. This chapter does into detail about oscillation as well as oscillatory motion.

Chapter 15 Waves

There different waves and their influences which will be understood through this chapter. Furthermore, this chapter will help you develop a conceptual study about the longitudinal and transverse waves, angular wave and wavelength number, frequency, and angular frequency, etc.
