Physics

This chapter introduces us to the branch of science that deals with the nature of matter and energy. It also provides knowledge on some major branches of physics, the fundamental forces of nature, and famous scientists and their contributions are listed here.

This chapter deals with matter and its properties. It also explains about pressure, density and relative density. We will also learn in detail about molecular motion among the three states of matter along with their properties.

This chapter discusses various physical quantities and the concept of motion and rest. It also explains about motion and force, Newton’s law of motion and Einstein’s theory of relativity along with circular motion and frictional force.

This chapter deals with the concepts related to work, power and energy. It also explains the different forms of energy and collisions. This chapter further discusses the conservation of energy and the working principle of an engine.

This chapter highlights the nature of heat and the different laws of thermodynamics. It also discusses the different types of thermometers and processes that cause a change in the state of matter and the processes involved in the transmission of heat.

This chapter explains the nature and properties of a wave. It also explains in detail about mechanical waves and electromagnetic radiation. A brief note on the propagation of electromagnetic waves in the atmosphere is also provided here.

This chapter highlights the nature, speed and types of sound waves with its characteristics. It also explains the production and propagation of sound. We will also learn about echo, resonance, Doppler’s effect, supersonic and subsonic speed in this chapter.

This chapter deals with the sources, characteristics features and properties of light. This chapter also discusses the image formation on different types of mirrors, eclipses and shadow formation. A brief note on human eyes and colour vision is also given here.

This chapter deals with magnetism and its properties. It also discusses in detail the history and cause of magnetism, magnetic field and lines of forces along with magnetic materials. It also briefs about the earth’s magnetism in this chapter.

In this chapter, we will learn in detail the conduction of electricity. It also explains about the different effects and laws related to electricity. This chapter further provides information on electrochemistry and the types of cells.

This chapter explains about the nucleus, nuclear forces and radioisotopes. It also deals with the basic terms in nuclear science and applications of nuclear energy. A brief note on India’s nuclear energy programme and radioactive decay law is also given here.

This chapter comprises questions related to Physics for practice. By answering these questions, you can assess your conceptual knowledge and will also help you understand the concepts better.
