Today we hurriedly covered equations for the position, velocity, and acceleration of an object at any one time undergoing Simple Harmonic Motion. We also talked about equations to find the period of a mass on a spring and a pendulum. We went quite fast and all of this is important for you to know (there will be probably ~5 mulitple choice questions covering this information). I wish we had more time, but we just don’t.
To help you with this, your homework is to do the “Monterey” videos at this website. Watch the videos, answer the questions. Remember, they go fast, you can always stop the video and walk step by step through their solutions using the buttons at the top. Don’t stress too much over the last sections which can sometimes contain pretty tough information that isn’t worth stressing over.
The video we watched at the end of class today was one of the MIT lectures from Dr. Walter Lewin. You can download all of them from iTunes by clicking this link or you can go to the course website here, where you see all kinds of course material. We watched the end of lecture 10 today. Some of what he said didn’t make much sense because we started at the end of the lecture. If you watch all the way through, it should be a little clearer.
There are a lot of great resources on the web to help you with this Physics. I know a lot of you haven’t been very good about doing your homework. If you don’t do some work at home, the $86 for the AP Test will be wasted. If you bust your behind, you can pass this test. It looks really good on a college application to say you’ve passed AP Physics-C…it’s a tough class!
KATE…….REALLY
