OSCILLATIONS. 13.1 INTRODUCTION. In our daily life we come across various kinds of motions. You have already learnt about some of them, e.g., rectilinear motion and motion of a projectile. Both these motions are non-repetitive. We have also learnt about uniform circular motion and orbital motion of planets in the solar system.

Introduction to Oscillations and Waves covers the basic mathematics and physics of oscillatory and wave phenomena. By the end of the course, students should be able to explain why oscillations appear in many near equilibrium systems, the various mathematical properties of those oscillations in various contexts, how ….

Figure 4.1: Harmonic Oscillation of a mass at a spring. At the maximum elongation the spring is pulling on the mass. The mass gets accelerated towards the equilibrium position. At the equilibrium position the acceleration is zero and the velocity of the mass reaches its maximum.
The repeated back and forth movement between two positions or states of an object is known as oscillation. It can also be referred to as the periodic motion that has the tendency to repeat itself in a regular cycle. For example- a sine wave, with a side-to-side pendulum swing, or the up-down motion with a weight of a spring.
This course studies those oscillations. When many oscillators are put together, you get waves. Almost all physical processes can be explained by breaking them down into simple building blocks and putting those blocks together.
