This program covers the important topic of oscillations (part 2) and simple harmonic motion in Physics. We begin by discussing how oscillations arise in nature and how everyday processes such as pendulums lead to simple harmonic motion. We also discuss how this motion can be modeled by a sinusoid. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed...
