An oscillation is a back and forth motion of an object between two points of deformation. An oscillation may create a wave, which is a disturbance that propagates from where it was created. The simplest type of oscillations and waves are related to systems that can be described by Hooke’s law.
13.1 - Simple Harmonic Motion Oscillations Free oscillations occur when no external force is continuously acting on the system, so its energy remains constant. The system will oscillate at its natural frequency . Examples of systems which experience free oscillations are:
Unit 1 Welcome to oscillations & waves. Unit 2 How does mass of an attached object affect the motion of a spring?
We begin by studying the type of force that underlies the simplest oscillations and waves. We will then expand our exploration of oscillatory motion and waves to include concepts such as simple harmonic motion, uniform circular motion, and damped harmonic motion.

By studying oscillatory motion and waves, we shall find that a small number of underlying principles describe all of them and that wave phenomena are more common than you have ever imagined. We begin by studying the type of force that underlies the
Free and forced oscillations When an object oscillates without any external forces being applied, it oscillates at its natural frequency. This is known as free oscillation. Forced oscillation occurs when a periodic driving force is applied to an object, which causes it to oscillate at a particular frequency. Resonance
