Contents

NCERT Solutions for Class 11 Physics consist of clear, detailed solutions for all the questions present in the prescribed NCERT textbooks. These answers are provided by our experts, to ensure that the answers are helpful to the students.

Year 11 and 12 are the most important in a student’s life, as this is what determines what college they’ll get into. Year 11 standard is especially important, as this is when the foundation for all the subjects is laid. The basics, if not cleared now, will cause a lot of trouble in understanding the advanced topics in later years.

NCERT Solutions for Class 11 Physics

physics class 11 is an especially tricky subject that a lot of students struggle with. It takes a lot of practice to master these concepts. Hence, it is recommended that the student go through the simple explanations provided in the NCERT Class 11 physics textbook and try answering all the exercise questions.

If they are stuck, the solutions provided here will help them out. The answers are organized in a plus one physics chapter wise questions and answers format so that the student can immediately find what they’re looking for.

Class 11 Physics NCERT Solutions Chapter wise

Class 11 Physics Chapter 1 Physical world

This NCERT solutions for class 11 physics introductory chapter gives the student an overview of the subject itself. It introduces the various sub-disciplines and discusses the fundamental forces present in nature. The class 11 physics chapter concludes with a thought-provoking discussion on symmetries and conservation laws.

Class 11 Physics Chapter 2 Units and measurements

This is a crucial physics class 11 NCERT solutions chapter for any discipline in physics. The quantities in physics rely heavily upon the units used to express them. Also, it is fundamental for the student to understand what dimensions of a quantity are. Hence, this 11th physics chapter introduces the student to these concepts and more, touching upon various measuring devices and the international system for units and measurements. The NCERT 11 physics chapter also teaches the student how to express errors.

Class 11 Physics Chapter 3 Motion in a straight line

The NCERT physics class 11 students have been exposed to rectilinear motion before, but beyond brushing up those old concepts, the chapter introduces them to the concept of frames of reference and rthe elative motion.

Class 11 Physics Chapter 4 Motion in a plane

Building upon what was taught in the previous 11th physics chapter, the student is now taught how to handle motion in 2 dimensions. They are also introduced to the crucial concept of vectors and are taught how to handle vector addition.

Class 11 Physics Chapter 5 Laws of motion

Moving past how bodies move, now the student is asked to wonder why the bodies move. They begin with the ancient schools of thought, including Aristotle’s fallacy, and expand upon them little by little until settling on the currently accepted Newton’s laws of motion. The physics class 11 student is taught when a body is in equilibrium and what causes it to leave the state. Conservation of linear momentum is also briefly discussed.

Class 11 Physics Chapter 6 Work Energy and Power

In this NCERT solutions for class 11 physics chapter, the student is introduced to the concepts of work, energy, and power, and are taught how the first two are interconvertible. An intuition for the law of conservation of energy is built into them as they explore the change in potential and kinetic energies of a spring as it contracts and lengthens.

Class 11 Physics Chapter 7 System of Particles and Rotational motion

Until now, the student has dealt with the simplified cases of point objects. In this class 11 physics chapter, they are taught to handle extended bodies. The approach is simplified by considering the motion of the centre of mass of the body. They are also taught the rotational analogue of various parameters, like torque for force, moment of inertia for inertia, etc.

Class 11 Physics Chapter 8 Gravitation

Gravity is one of the 4 fundamental forces. In this chapter, the nuances of the same are discussed, as the class 11 physics student learns how gravitation was perceived in the past and how the perceptions have changed with time. They learn of many applications, from weightlessness to satellites and planetary motion.

Class 11 Physics Chapter 9 Mechanical properties of solids

In this chapter, the NCERT physics class 11 students learn about how solids behave under stress. They explore the various elastic properties of solids and discuss Hooke’s law in detail. They also get an idea of the applications of this theory.

Class 11 Physics Chapter 10 Mechanical properties of fluids

This NCERT physics chapter completes what was begun in the previous class 11 physics chapter. The behaviour of fluids is not as intuitive as is that of solids. Hence, each topic is slowly introduced as the student learns about pressure, streamlined and turbulent flow, etc. They learn about Bernoulli’s law and its various applications in real life.

Class 11 Physics Chapter 11 Thermal properties of matter

This chapter discusses the various aspects of heat and temperature. The class xi physics students learn about the various modes of heat transfer, i.e. conduction, convection and radiation. They learn about how substances react to being heated or cooled and uncover the mystery behind various baffling phenomena, such as why the temperature of water does not change as it transitions from liquid to ice.

Class 11 Physics Chapter 12 Thermodynamics

Thermodynamics is the study of the conversion of heat into other forms of energy. It is a macroscopic science and does not delve into the behaviour of every individual particle. In this NCERT physics chapter, the student learns about the zeroth law, that establishes the definition of temperature, the first law, which is a form of the law of conservation of energy, and the second law, that introduces the counter-intuitive concept of entropy, and is an iron-clad rule that can never be broken. The class 11 physics chapter also discusses ideal heat engines, refrigerators and Carnot cycles.

Class 11 Physics Chapter 13 Kinetic theory

This 11 class physics chapter introduces the student to the kinetic theory of gases. which provides a molecular model to work with. The theory consists of the idea that gases can be approximated as rapidly moving atoms or molecules. This is used to explain various properties such as temperature, pressure, etc.

Class 11 Physics Chapter 14 Oscillations

This NCERT Solutions for class 11 physics chapter introduces students to periodic motion, oscillatory in particular. They learn about all the aspects of simple harmonic motion, which is a very important model that can be applied in various situations. They are also briefly introduced to the more realistic model of damped oscillations.

Class 11 Physics Chapter 15 Waves

This is a very important class 11 physics chapter whose principles and theories will be applied in various fields of physics. This chapter might prove challenging to the students, as the propagation and properties of waves are not quite intuitive. This 11th physics chapter helps the student understand the properties of light and sound waves.

As these class 11 Physics NCERT solutions chapters build upon what was taught in previous years, it is recommended that the student refers to NCERT solutions of class 10 Physics if they aren’t able to understand a topic quite completely yet. The links for the same are listed down below.
