The Solutions for all Physical Sciences Grade 12 Learner’s Book, includes sufficient practical tasks to ensure that you develop the skills necessary to become a true scientist. The subject matter of physical sciences is organised in six main knowledge areas.
Simple harmonic motion (SHM) is oscillatory motion for a system where the restoring force is proportional to the displacement and acts in the direction opposite to the displacement. Maximum displacement is the amplitude A.

The description of a periodic motion, in general, and oscillatory motion, in particular, requires some fundamental concepts, like period, frequency, displacement, amplitude and phase. These concepts are developed in the next section. 13.2 PERIODIC AND OSCILLATORY MOTIONS. Fig. 13.1 shows some periodic motions.
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.
The electromagnetic waves that you will learn in Class XII are a different type of wave. Electromagnetic waves do not necessarily require. a medium - they can travel through vacuum. Light, radiowaves, X-rays, are all electromagnetic waves.
Lecture Video: Periodic Oscillations, Harmonic Oscillators. In this lecture, Prof. Lee discusses the mathematical description of the periodic oscillation and simple harmonic oscillators. The first 5 minutes are devoted to course information. Beginning of dialog window.
