Motion, Force and Work

This chapter describes the motion of an object by its speed, direction, velocity and acceleration. Uniform motion and uniformly accelerated motion with their equations are also explained with graphical representations.

This chapter covers Newton's laws of motion that derive a relation between the force acting on the body and the motion of the body. We will also learn the different types of forces, definitions of each law and the concept of conservation of momentum.

This chapter discusses the concepts of gravitation with the description of universal law constant, acceleration due to gravity and their standard values. The concepts of free fall, equations of motion and Archimedes' principle are also discussed here.

This chapter covers the concepts of work, energy and its forms with the expressions of kinetic and potential energy, power and the laws of conservation of energy. The unit of energy is also discussed here with its derivation.

In this chapter, we will learn about the sound that is produced by vibrating objects and its propagation via a medium through an activity. It also discusses the waves, echo and the properties of sound waves.
