Chapter 12

Simple harmonic motion

LEARNING OBJECTIVES

In this chapter you will learn how to:

●identify the conditions under which simple harmonic oscillations take place

●identify and use the concepts of period, frequency, amplitude and displacement

●analyse simple harmonic oscillations graphically

●identify the connection between angular frequency and period

●describe the energy transfers taking place in oscillations and analyse them graphically

use the equations that describe simple harmonic motion

understand the concept of phase angle and phase difference

use the quantitative approach to energy in simple harmonic motion.

GUIDING QUESTION

Why are simple harmonic oscillations the basis for understanding all oscillations and all wave motion?
