Physics phriends!
Welcome and thanks for an exciting first day. I don't know about you, but I'm pretty stoked for a great year.
To summarize your homework:
1. Does the whirligig spin clockwise or counterclockwise?
2. Can you reverse it (and how)?
3. Think of applications; where you've seen this behavior previously.
4. Explain! (As best you can, without research.)
5. Investigate the toilets and sinks in your home (and elsewhere, if you wish). Do they drain CW or CCW?
Thanks again, and welcome to physics!
