Unit D Introduction

 

This unit is about 25% of the Physics 20 course. This is equivalent to approximately 20 80-minute classes. You may have to do additional “homework” hours to complete this unit.

 

In this unit you will investigate simple harmonic motion and mechanical waves. This will prepare you for further study of simple harmonic motion and wave phenomena in other physics courses.

 

The major concepts developed in this unit are for you to be able to

• describe the conditions that produce oscillatory motion
• describe the properties of mechanical waves and explain how they transmit energy

Think about the following questions as you complete this unit:

• What are examples of oscillatory motion in the world around you?
• How do mechanical waves transmit energy?
• How is structural design and development of technologies influenced by the understanding of wave properties?
