NCERT Solutions Class 11 Physics Chapters small intro

Chapter 1: Physical World

Chapter 1 is basically is the building block essential for you to comprehend the concepts of physics that are yet to be studied in the future. Physical World deals with the study of Science, Mathematics, Natural Sciences, forces, Physics, right from the basic, its important applications, and what impact it has. In Physics Class 11 Chapter 1 Ncert questions, we have covered all the important topics. It gives students a basic understanding of the past and the development of laws in physics.

Chapter 2 Units and Measurement

This chapter focuses on introducing you to the units, it’s definition, types, base units, derived units, and numerous other things.  The introduction to the International System of units is given. The important methods for measurements such as the parallax method, parallax angle, and other methods to measure length are included. Additionally, you will learn about the alternative methods to measure length and estimation of very small distances like the size of a molecule.

Chapter 3 Motion in a Straight Line

This chapter is a very interesting part of the Kinematics. In junior classes, we all have learned about motion and its fundamental properties. This chapter aims at teaching you the rectilinear motion, its measurements, and the various parameters related to it. In the chapter, motion in a straight line, you will learn what is the frame of reference, reference point, what is called as path length, how can we find the magnitude of displacement, relative velocity, instantaneous velocity, acceleration, retardation, etc.

Chapter 4 Motion in a Plane

This chapter aims at providing you the information about how to measure motion in a plane and what the scalar and vector quantities are. Derivative laws of the addition of scalar and vectors are explained with the help of diagrams in this chapter. The various concepts like position and displacement vector, multiplication of vectors by real numbers, equality of vectors, addition, and subtraction of vectors through a graphical method, resolution of vectors and addition of vectors through an analytical method are the main topics explained in this chapter.

Chapter 5 Law of Motion

Till this chapter, you have been acknowledged with the basics of motion and the various parameters. You will learn topics like how bodies move, factors that act on them, the direction of force and their corresponding motion, the effect of gravitation, and others are explained clearly in this chapter. Motion has been the center of research for the World’s physicists. The contribution of these physicists such as Aristotle, Newton, and Galileo to study motion is also mentioned in this chapter.

Chapter 6 Work, Energy and Power

The basic terms of work, energy, and power are the concepts that must have been learned about them in earlier classes. What is different in this chapter is you will be learning as to how these three quantities are related, i.e. work, energy and power. The main topics will include the Scalar product and its distributive laws taught in this chapter which lays the base for the further complicated topics.

Chapter 7 Systems of Particles and Rotational Motion

This chapter explains the theoretical and mathematical part of the systems of particles and the rotational motion. These concepts have been explained in a very clear and comprehensive manner for ease of students and better understanding.

Chapter 8 Gravitation

You might be conscious that every one item generally tends to get drawn to the earth. college students are consequently, aware of the fundamental concept of gravity, how it became discovered, and the results of the identical. however, chapter 8 of sophistication eleven Physics, Gravitation, takes you into the depths of the concept of Gravitation. on this bankruptcy, you will get an awesome grip over the technical foundation of gravitation, regularly occurring regulation of gravitation, Kepler’s legal guidelines, Acceleration because of gravity of the earth, Acceleration because of gravity underneath and above the surface of the earth, the gravitational consistent, Gravitational ability electricity, Earth satellites, break out velocity, the electricity of an orbiting satellite, Geostationary, and polar satellites and Weightlessness

Chapter 9 Mechanical Properties of Solids

In Mechanical homes of solids, you’ll have a look at approximately the bodily residences of solids, such as plasticity, elasticity, and others. The essential properties of solids are comfortable to be had to research on this chapter. strain, compressive strain, tensile pressure, longitudinal stress, tangential or shearing stress, shearing stress hydraulic strain, and volume strain are some of the ideas so one can construct the muse for mastering the houses of solids.

Chapter 10 Mechanical Properties of Fluids

In this chapter, you will learn about certain common body fluids. How is liquid different from solids? What are the common characteristics of beverages and gases? Also, the difference between gases and solids or liquids, are some of the questions answered in this chapter. Also, the effect of external forces such as pressure and fluid resistance is clarified with the help of mathematical discourses in this chapter.

Chapter 11 Thermal Properties of Matter

In this chapter, you will learn the true meaning of temperature and how it is measured. You will learn various processes where heat travels. As you progress, you will discover why metal makers burn the metal ring before inserting it into the wooden wheelbarrow wheel and why the air on the seashore tends to bounce back to where the sunsets. What happens when water boils or freezes? You will learn why its temperature does not change during these processes even though intense heat flows in or out of it.

Chapter 12 Thermodynamics

Thermodynamics is that branch of physics that deals with the concepts of heat and temperature as well as thermal modification and other forms of energy. It’s great science. It works on multiple systems and does not include the cellular constitution of any issue. In this chapter, you will learn about the laws governing thermal energy and the processes by which they work is converted into heat and vice versa.

Chapter 13 Kinetic Theory

You will learn about the function of a gas in terms of the idea that gas contains atoms or molecules that move faster. Kinetic Theory has been studied since the 19th century by such famous scientists as Newton, Maxwell, Boltzmann, Boyle, Avogadro, and others. This chapter also introduces kinetic theory.

Chapter 14 Oscillations

Chapter 14, Oscillations, is important and very interesting. This is the next step after learning about rectilinear movements, motion projectile, and others in the lower grades. The study of oscillatory movements is fundamental to physics; concepts needed to understand many physical events. The chapter breakdown will help us learn more about the impact of oscillatory movements and movements.

Chapter 15 Waves

In the Oscillations, you will learn the movements of moving objects alone. This chapter will help you to understand the concept of waves and their various waves. This chapter will be of great help to you in the study of the concept of wavelength and longwave, Transmission of Relationships in the Progressive Wave, Wavelength and Angular Wave Number, Amplitude and Phase, Period, Angular Frequency and Frequency, Speed ​​of a Transverse Wave on Stretched String, The Speed ​​of the Moving Waves, The Speed ​​of the Long Wave (Sound Speed), the System of the Raising Wave, the Display of Waves, and much more.

There are step-by-step solutions to the various problems in the textbook that ease any stress you may have before your examinations. The solution acts as the perfect guide right before your examinations as it contains details on the questions that are asked quite often.
