Fourier Waves
- Explain qualitatively how sines and cosines add up to produce arbitrary periodic functions.
- Recognize that each Fourier component corresponds to a sinusoidal wave with a different wavelength or period.
- Mentally map simple functions between Fourier space and real space.
- Describe sounds in terms of sinusoidal waves.
- Describe the difference between waves in space and waves in time.
to answer the questions posed here
Hope you feel better soon.

Waves on a String
http://phet.colorado.edu/en/simulation/wave-on-a-string
Prnt the worksheet here
Go through the reading http://www.physicsclassroom.com/Class/waves/u10l1a.cfm (there are actually 7 screens that cover Lesson 1 and 2)
Draw a wave and its parts
Summarize what you have done.

Types of Scales
Tell me how scales work, and how it is related, or NOT related, to Hooke's Law. A quick search on Google Images shows me scales of justice, dial scales, doctor scales, fishing scales and digital scales. Pick 3 of these. Show me for each....a) how it works b) how it is/is not related to the material covered thus far and c) how accurate you believe it to be and why.
Good luck

The Math of Hooke's Law and the Pendulum
http://www.physicsclassroom.com/class/energy/u5l1b.cfm
You need to copy the formulas into your front cover and then complete the worksheet. Each problem MUST have a drawing, variables circled, and a formula /work to receive credit.

Pendulum Problem
1) what variables affect the period of a pendulum? Explain how you know this from your lab.
2) design a pendulum that has a period of exactly one second on Earth, and one second on the Moon. To do this, you will need to find the formula for a pendulum and create a drawing, variable set, and formula work.
