Class 11 Physics

15 Chapters

Class 11


Class 11 Physics will help understand the fundamentals of the subject in an efficient manner. Physics of class 11 deals with a total of 15 chapters. The first chapter here is the physical world that deals with topics related to various physical forces. The next chapter here is Units and Measurement that deals with unit, base units, system of units, derived units, etc. Motion in a straight line explores Kinematics further. Furthermore, Motion in a plane will teach you about the measurement of motion in a plane. Moreover, the Law of Motion chapter deals with the motion of a particle in space. Work, Energy, and Power chapter explores the relation between these three quantities. Systems of Particles and Rotational Motion explores the mathematical and theoretical part of these concepts. Gravitation chapter deals with the concept of gravitation in a detailed manner. Mechanical Properties of Solids chapter will teach you about the various physical properties of solids. Another chapter Mechanical Properties of Fluids will teach you about the various physical properties of gases and liquids. Thermal Properties of Matter is all about heat and its measurement. Thermodynamics is a macroscopic topic revolving around heat and temperature. Kinetic Theory explores the behaviour of gases. Oscillations chapter will take you in the depths of this concept. Finally, the Waves chapter deals with the conceptual study of waves.

Chapter 1 : Physical World

How and why does ice float? How do we cook? How does a car or your TV work? Why don't your legs break when you jump off a chair? The answer to all these questions involve physical world principles we study in physics. And what is physics? What are its scopes and how does it help us every day? Let us know more.

Chapter 3 : Motion in a Straight Line

We see leaves falling from trees and water flowing from the river. We walk, we run, we drive a car these are the activities that we carry out in our day to day life.These activities can be simply defined a motion. Let us study more about motion in a straight line.

Chapter 4 : Motion in a Plane

Have you ever played a bike racing game on your video games? And observed the motion of the bike as control it from the remote? Well, this motion of the bike is in a plane and can be explained by the laws of physics. Let's study the motion in a plane with the topics of vectors, circular and projectile motions.

Chapter 5 : Laws of Motion

Take a ball and slide it across the floor. Can you see it keeps sliding?The ball rolled on the floor will keep sliding unless stopped by you. Why does this happen? The above-mentioned activity is an application of Newton's first law of motion.Let us study about the force and laws of motion-in-depth.

Chapter 6 : Work, Energy and Power

We all have heard 'Work is Worship'. But not in Science. In Science, Work is the product of Force and Distance. When talking about Work, we come across terms like Energy, Power, Distance, Displacement, Force and lot more. In this chapter, we'll learn about Work, Energy and Power.

Chapter 7 : Systems of Particles and Rotational Motion

Have ever spun a bike wheel or pushed a merry-go-round? Also, everyone must have spun the top. These are nothing but the examples of '' Rotational Dynamics ''. Let us now study in detail about the system of particles and rotational dynamics.

Chapter 8 : Gravitation

After Newton discovered the gravity people came to know about gravity. Furthermore, now a day’s everybody knows what is gravity. So, to find out more go through the topic to learn about gravitational force, gravitational force formula, formula’s derivation and solved example.

Chapter 9 : Mechanical Properties of Solids

A material is said to be in the solid state if all the atoms of that matter are densely packed together. A solid material has a definite shape and size. In order to change the shape and size of the solid object, an external force needs to be applied.

Chapter 10 : Mechanical Properties of Fluids

A fluid is a substance that has no fixed shape. Liquids and Gases can flow and are therefore called fluids. Fluids yield easily to external pressure. In this chapter, we will learn about various Mechanical Properties of Fluids like Viscosity and Surface Tension.

Chapter 11 : Thermal Properties of Matter

The Matter is defined as any substance that has mass and occupies space. Temperature is one of the most important physical properties of matter. Also, there are other temperature related properties of matter like thermal conductivity, thermal diffusivity and so on. Let's find out more...

Chapter 13 : Kinetic Theory

If you could go back in time, maybe a few hundred million years after the Big Bang, you will see that the entire Cosmos was mostly gas. How did those clouds of gas, form the most complex objects like the galaxies and their clusters? We shall learn all about the kinetic theory of gases in this chapter.

Chapter 14 : Oscillations

Tik-Tok, Tik-Tok. The hands of a clock never stop, do they? They keep repeating their motion after a certain time. But a pendulum, after it is swung, comes to a stop. Why? What is the motion of a pendulum called in the first place? Let's learn all about Oscillations.

Chapter 15 : Waves

At some point or the other, all of us have experienced 'Eavesdropping'. Isn't it? But how do we eavesdrop? How is that we can hear everything whilst being behind those closed doors? Let us try and understand the sound waves better.
