This reference is called unit and 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). A set of these units to measure physical quantities of various types forms a system of units.
You will learn about the popular systems of units, like the CGS, FPS, and MKS systems of units. You will also learn about the measurement of mass, length, and time. The chapter also explains the various types of errors in measurement as well as accuracy and precision of measuring instruments.

There are an ample number of numerical examples in this chapter to help you understand all these concepts better.
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.

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. A sufficient number of diagrams are used to explain these concepts. Once these basic concepts are clear, motion in a plane with constant acceleration, relative velocity in two dimensions, projectile motion and uniform circular motion will be explained in details.

Lastly, the chapter explains the kinematics of rotational motion, dynamics of rotational motion, and angular momentum in case of rotation about a fixed axis followed by rolling motion.
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 various concepts related to it. You will start with Kepler’s laws which will be followed by the universal law of gravitation, the gravitational constant, acceleration due to gravity of the earth, acceleration due to gravity below and above the surface of the earth and gravitational potential energy. After that, this chapter will deal about escape speed – the speed with which an object should be thrown so that it escapes the gravitational force of the earth. This discussion will then lead to earth satellites, the energy of an orbiting satellite. geostationary and polar satellites and final the fascinating concept of weightlessness.
NCERT Solutions For Class 11 Physics Chapter 9: Mechanical Properties Of Solids
You have learnt that the motion of a body depends on how mass is distributed within the body. However, your understanding was restricted to simpler situation of rigid bodies wherein 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.
You will be introduced to the elasticity – the property of solids by virtue of which it changes its form when a force is applied to it but regains its original form when the force is removed – and plasticity – the property by virtue of which a solid retains its changed form even after the force is removed. A scientific explanation of the elastic behaviour of solids will be given to you followed by the concepts of stress and strain. These will be followed by the Hooke’s law, stress-strain curve and elastic moduli. Lastly, you will learn about the applications of elastic behaviour of materials. There are plenty of diagrams and numerical examples in this chapter to illustrate the various concepts.

Kinetic Theory is a very successful theory developed by Maxwell, Boltzmann and other scientists in the 19th century, that explains the behaviour of gases. This theory is based on the assumption that the gas comprises atoms and molecules which moves rapidly as inter-atomic forces in gases can be neglected.
This chapter deals with this theory and starts off by explaining the molecular nature of matter and behaviour of gases.

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 understand various physical processes.
