Physics

This chapter discusses the different kinds of motion. It includes various formulas related to the force. It explains the concept of centrifugal and centripetal force. We will also solve some problems based on torque and centre of gravity.

This unit covers the concept of work, such as work done by constant and variable forces, types of energy and more. It elaborates on the three physical quantities, namely work, energy, power, with their significance.

This chapter explains the working of a machine. It discusses the block and tackle system. It describes different classes of a lever. We will also learn how to solve questions based on an inclined plane.

In this chapter, we will learn about refraction through a plane surface. We will study the phenomenon of total internal reflection. In addition, it explains the laws of refraction with the help of labelled diagrams.

In this chapter, we will learn about the real and virtual images in detail. It discusses the function of the power lenses, including their magnification and focal length. It also briefs on the working mechanism of a simple microscope.

In this chapter, we will learn about the electromagnetic spectrum. We will understand the mechanism of dispersion of light. Furthermore, we will go through a table highlighting the uses of electromagnetic waves.

This chapter will talk about sound. How it is produced and how it reaches humans is discussed here. Through an experiment, we study that the sound cannot travel in a vacuum. The three categories of sound based on the hearing range is also learned here.

This chapter talks about the potential and potential difference of a cell, free electrons, and the current flowing through a wire. It also briefs on the conductors and insulators. Moreover, it discusses Ohm?? law and resistance.

This chapter describes the electric energy, electric power, and electric current. It explains the phenomenon of earthing and the use of a fuse. We will also learn about materials that are used to make different devices.

This chapter sheds light on the concept of magnetism, magnetic field due to currents, and electric motors. It explains the electromagnetic induction along with an electric generator. We will also learn about alternating and direct currents.

This chapter talks about Heat. It explores the concept of mixtures. It discusses thermal equilibrium, heat, and temperature. It sheds light on the Determination of specific heat and its applications.

The chapter describes the constituent particle of an atom, along with how electrons and neutrons can move inside an atom. It also explains the various parts of electronic devices and the concept of the solar system.
