TEXTBOOK:  Chapter 12, pages 443 - 448.

OBJECTIVES:

• State three examples of objects which undergo simple harmonic motion.

• Specify the effect of a change in length, mass, or amplitude on the period of a pendulum. 

• Explain the meaning of the following words for an object undergoing simple harmonic motion: amplitude, displacement, frequency, period.  

• Specify the relationship between frequency and period, and given one, calculate the other. 

• Define simple harmonic motion in terms of restoring force and displacement.  

• Identify points in simple harmonic motion where the velocity is zero or where it achieves its maximum values.  

• Identify points in simple harmonic motion where the acceleration is zero or where it achieves it maximum values.  

• Explain how motion in a reference circle is related to simple harmonic motion.  

• Explain why simple harmonic motion is called a sinusoidal motion.  

• Solve problems using the formula for the period of a pendulum.
