Different kinds of topics related to different physical forces i. This chapter will clear your concepts about what is a unit, base units, derived units, system of units and much more. It will help immensely help you to understand what is the need and value international system of units and how are they decided. Various methods such as parallax method, parallax angle and other methods to measure length. One shall also learn on alternative methods to measure length and estimation of very small distances like the size of a molecule.
This chapter is a part of the Kinematics and is a very interesting one. In junior classes, we all have learned about motion and its fundamental properties. However, in this topic, you will get to know about rectilinear motion and its measurement having a detailed and technical vision. In the chapter, motion in a straight line, you will learn about the frame of reference, reference point, what is called as path length, magnitude of displacement, relative velocity, instantaneous velocity, acceleration, retardation, etc.
In this chapter, you will learn how to measure motion in a plane and what are scalar and vector quantities. Diagrammatic representation of Derivative laws of the addition of scalar and vectors are explained in this chapter. Topics 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 some of the primary topics explained in this chapter.
You have learned about the motion of a particle in space in some of the previous chapter and this chapter will move you ahead of the same. You will learn topics like how bodies move, factors that act on them, direction of force and their corresponding motion, effect of gravitation and others are explained clearly in this chapter.

Since ancient times, famous physicists have studied about motion. The contribution of these physicists such as Aristotle, Newton, and Galileo to study motion is mentioned in this chapter. You might be aware of the basic terms of work, energy and power as you have learned about them in earlier classes. What is different in this chapter is you will be learning the relation between these three quantities, i. You will also get to know Scalar product and its distributive laws taught in this chapter which is the is the foundation for further complex concepts. Chapter 7 — Systems of Particles and Rotational Motion.
This chapter explains the theoretical and mathematical part of the mentioned concepts. These concepts have been explained in a very clear and comprehensive manner for ease of students and better understanding.
You might be aware that all objects tend to get attracted to the earth. Students are thus, aware of the basic concept of gravity, how it was discovered and the effects of the same. However, Chapter 8 of class 11 Physics, Gravitation, takes you into the depths of the concept of Gravitation. In Mechanical properties of solids, you will study about the physical properties of solids, such as plasticity, elasticity, and others.
The fundamental properties of solids are readily available to learn in this chapter. Stress, compressive stress, tensile stress, longitudinal stress, tangential or shearing stress, shearing strain hydraulic stress, and volume strain are some of the concepts that will build the foundation for learning the properties of solids.
In this chapter, you will study some common physical properties of liquids and gases. How are fluids different from solids? What are the common characteristics of liquids and gases? Also, the difference between gases and solids or liquids, are some of the questions that have been answered in this chapter.
Also, the effect of external forces such as pressure and tension on fluids is elucidated with the help of mathematical expressions in this chapter. In this chapter, you will learn the actual definition of heat and how it is measured. You will study the various processes by which heat flows. As you go further, you will find out the reason why blacksmiths heat the iron ring before fitting on the rim of a wooden wheel of a horse cart and why the wind at a sea beach often reverses its direction after the sun goes down.

You will learn why its temperature does not change during these processes even though a great deal of heat is flowing into or out of it. Thermodynamics is that branch of physics that deals with the ideas of heat and temperature and the inter-conversion of heat and other forms of energy.
It is a macroscopic science. It deals with bulk systems and does not include the molecular constitution of any matter. In this chapter, you will study the laws that govern thermal energy and processes where work is converted to heat and vice-versa. You will learn the behaviour of gases based on the idea that gas consists of fast-moving atoms or molecules. Kinetic Theory is being studied since the 19th century by famous scientists such as Newton, Maxwell, Boltzman, Boyle, Avogadro and others. This chapter also introduces kinetic theory. Chapter 14, Oscillations, is an important and very interesting one.
This is the next step after learning about rectilinear motion, projectile motion, and others in the lower grades. The study of oscillatory motion is basic to physics; the concepts of which are required for the understanding of many physical phenomena. The chapter oscillations will help us to study in detail about oscillations and oscillatory motion. In Oscillations, you will study the motion of objects oscillating in isolation.
This chapter will help you to concepts of waves and different its types.
