ABSTRACT
This chapter introduces the concepts of linear and angular motion. It explains the relationships between displacement, velocity and acceleration. The chapter describes the relationship between absolute and relative velocities. It defines the equations used to analyse linear and angular motion. The chapter also introduces an approach by which linear and angular motion problems can be analysed. It also explains related topics such as 'falling bodies', 'trajectories' and vector methods. The car will cover a distance in a particular direction and will possess a particular velocity at any instant. During this process the car possesses the three basic constituents of motion, namely: displacement, velocity and acceleration. When a car sets off from traffic lights the driver depresses the 'accelerator' and the car steadily increases velocity. Velocity possesses magnitude and direction and can, therefore, be represented in terms of a vector. For instance, displacement becomes angular displacement, velocity becomes angular velocity and acceleration becomes angular acceleration.
