 Chapter 12
Simple harmonic motion
LEARNING OBJECTIVES
In this chapter you will learn how to:
âidentify the conditions under which simple harmonic oscillations take place
âidentify and use the concepts of period, frequency, amplitude and displacement
âanalyse simple harmonic oscillations graphically
âidentify the connection between angular frequency and period
âdescribe 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?
