NCERT Solutions for Class 11 Physics: Chapter Descriptions

Let us have a look at what each of the chapters in the NCERT syllabus of Class 11 Physics deals with:

This chapter, Physical World, is an introductory chapter that gives an overview of what exactly Physics is and how it tries to explain the various physical phenomena in terms of a few concepts and laws. The chapter then deals with various branches of Physics – Classical Physics and Quantum Physics – and what they are about. You will also get to know about the relationship between Physics, technology, and society.

NCERT Solutions for Class 11 Physics Chapter 2: Units & Measurement

In this chapter, you will learn how various physical quantities are measured. In order to measure physical quantities, a certain basic, internationally accepted reference standard is chosen. This reference is called a unit. Measurement involves a comparison of the physical quantity with this unit. There are fundamental units and derived units (which can be expressed as a combination of the fundamental units).

NCERT Solutions for Class 11 Physics Chapter 3: Motion In A Straight Line

This chapter starts by defining what exactly motion is – the change of position of an object with time – and then goes on to describe the motion of an object in a straight line. This is also called rectilinear motion. Various terms related to Rectilinear Motion – position, path length, displacement, average and instantaneous velocity and speed, acceleration are explained with necessary graphs and equations. You will also get to learn about kinematic equations for uniformly accelerated motion and relative velocity.

NCERT Solutions for Class 11 Physics Chapter 4: Motion In A Plane

In this chapter, you will get to know about the motion of an object in a plane, i.e. in two dimensions and its measurement. To start with, you will be introduced to scalars (quantities that have only magnitude) and vectors (quantities that have both magnitude and directions). You will learn about the multiplication of vectors by real numbers as well as the graphical methods of vector addition and subtraction. This will be followed by the resolution of vectors and the analytical method of vector addition.

NCERT Solutions for Class 11 Physics Chapter 5: Laws Of Motion

This chapter explains what causes motion. You will be introduced to the law of inertia followed by Newton’s first, second, and third law of motion. With detailed examples, you will get a clear idea about how objects move, what is force, the direction of force, and the resulting motion, the effect of gravitation, etc. The chapter also explains what momentum is and the conservation of momentum followed by the concept of equilibrium wherein the net force acting on a body is zero.

NCERT Solutions for Class 11 Physics Chapter 6: Work, Power & Energy

In this chapter, you will get to learn about work, power, and energy, three very commonly used terms, from a scientific point of view, and the relationship between these three physical quantities. With the Work-Energy Theorem derived from equations learned in previous chapters, you will get a clear definition of work. You will learn about the two types of energy – kinetic and potential energy.

NCERT Solutions for Class 11 Physics Chapter 7: Systems of Particles & Rotational Motion

This chapter deals with the theoretical and mathematical aspects of the motion of extended bodies. Various concepts, like center of mass and motion of centre of mass, the linear momentum of a system of particles, vector product of two vectors, angular velocity and its relation with linear velocity, torque and angular momentum, the equilibrium of a rigid body, moment of inertia, theorems of perpendicular and parallel axes are explained in details along with examples, diagrams, and graphs.

NCERT Solutions for Class 11 Physics Chapter 8: Gravitation

We all know that gravitation is what causes all objects to fall towards the earth. In this chapter, you will have an advanced understanding of the gravitational force and its various concepts. You will start with Kepler’s laws which the universal law of gravitation will follow, the gravitational constant, acceleration due to gravity of the earth, acceleration due to gravity below and above the earth’s surface, and gravitational potential energy. 

NCERT Solutions for Class 11 Physics Chapter 9: Mechanical Properties of Solids

You have learned that the motion of a body depends on how mass is distributed within the body. However, your understanding was restricted to a simpler situation of rigid bodies – you have studied the motion of rigid bodies wherein the hard solid body has a definite shape and size. However, in real life, bodies, even a rod of iron is not rigid in the truest sense of the word – it can be bent, stressed, or compressed. So, in this chapter, you will learn about such mechanical properties of solid objects.

NCERT Solutions for Class 11 Physics Chapter 10: Mechanical Properties of Fluids

Liquids and gases are called fluids as they can flow. In this chapter, you will learn about some basic physical properties of fluids. The chapter also deals with how fluids are different from solids, the similarities and differences between liquids and gases, etc. The chapter starts off with the concept of pressure and then explains various concepts, like streamlining flow, Bernoulli’s principle, viscosity, and surface tension. All these concepts are explained in detail with diagrams, equations, and numerical problems.

NCERT Solutions for Class 11 Physics Chapter 11: Thermal Properties of Matter

We all use the terms ‘heat’ and ‘temperature’ in our day-to-day life. This chapter gives a careful and scientific explanation of these two terms. Starting off with the definition of heat and temperature, the chapter explains how temperature is measured. This is followed by the ideal gas equation and the concept of absolute temperature. Then you will learn about the thermal expansion of matter – how solid, liquid, and gas expand with temperature.

NCERT Solutions for Class 11 Physics Chapter 12: Thermodynamics

In this chapter, you will learn about the laws governing thermal energy and study the processes in which work is converted into heat and vice versa. The chapter starts off with the concept of thermal equilibrium followed by the Zeroth law of Thermodynamics. You will then learn how heat and work in thermodynamics help in energy transfer to a system resulting in a change in its internal energy.

NCERT Solutions for Class 11 Physics Chapter 13: Kinetic Theory

This chapter deals with this theory and starts off by explaining the molecular nature of matter and the behaviour of gases. You will then study the kinetic theory of an ideal gas and the law of equipartition of energy. You will then move on to the specific heat capacity of monatomic gases, diatomic gases, polyatomic gases, solids, and water. Lastly, you will learn about the mean free path.

NCERT Solutions for Class 11 Physics Chapter 14: Oscillations

In this chapter, you will learn about a new type of motion – oscillations or oscillatory motion – the to and fro motion of an object about a mean position (Ex: the motion of a pendulum). Also called vibrations, this is a very important concept that is important to understanding various physical processes.

NCERT Solutions for Class 11 Physics Chapter 15: Waves

Here, you will study the oscillatory motion in a system or a collection of objects, for example, a material medium. You will be introduced to waves which are patterns that move without the actual physical transfer of matter as a whole. You will get to know about transverse and longitudinal waves, displacement relation in a progressive wave, and the speed of a travelling wave. The principle of superposition of waves and reflection of waves will also be explained.
