Physics

This chapter deals with motion and its types. It defines distance, displacement, and velocity. We will learn about uniform and non-uniform motion with the aid of examples. It also explains acceleration and equations of uniform accelerated motion.

In this chapter, we will learn about Newton's laws of motion. Each law is explained in detail with the aid of activities. It discusses inertia, mass and acceleration. A brief note on the conservation of momentum and impulse is also given here.

This chapter describes the refraction of light at plane surfaces. It explains the relative refractive index, total internal refraction, and the applications of total internal reflection. It briefs on the refraction of light through a glass slab.

This chapter deals with gravity and gravitational force. It explains the universal law of gravitation and acceleration due to gravity. Mass, weight, and free-falling of the body are also discussed here in detail along with their derivations.

This chapter explains the concept of thrust and pressure with their units. It elaborates on Archimedes’ principle and its application. We will learn about buoyancy and how to measure the force of buoyancy. It also explains Pascal's principle.

This chapter describes the term work with the aid of examples. It explains kinetic, potential, and mechanical energy along with the units and derivations. It also discusses the law of conservation of energy and sources of energy.

This chapter provides knowledge of thermal equilibrium. It explains specific heat and its applications. It details the method of mixtures and its principles. It briefs on evaporation, condensation, boiling, melting, and freezing.

In this chapter, we will discuss the production and propagation of sound through different mediums. We will come across the description of some musical instruments. It also highlights the structure of the ear with the help of a well-labelled diagram.
