3/18 Physics update and homework due 3/25

Hi folks,

Today we spent a bit of time reviewing some energy and momentum concepts that the quizzes indicated may need a bit more work. We also spent quite a bit more time clarifying and working with waves. Using a rope, the students explored the relationship between frequency and wavelength.

Homework for this week is to:

Do the Think and Explain Questions on page 388 of the Conceptual Physics book #'s 1-5

Do the think and solve problems on page 399 #'s 1 - 4

Answer the following questions:

1. When you shook the rope, how did moving your hand effect the frequency of the rope wave?

2. When you shook the rope, how did moving your hand effect the wavelength of the rope wave?

3. What is the relationship between frequency and wavelength?

4. What did you do the affect the amplitude of the rope wave?



EXTRA CREDIT: Find a swing and figure out the frequency and period of the swing.

EXTRA CREDIT: Go to a pond or a pool and find the frequency, wavelength and velocity of some water waves you create.
