Click here for the website I used in class today to simulate a wave on a string. You can change variables to see how it affects the wave!

There are lots of mobile apps on Quizlet’s website!
Quick Tips:
- Click the grey shuffle symbol to, uh, shuffle cards.
- Uncheck “both sides”
- Check “Term First”

There seems to be some confusion going around about Friday’s physics lab!
A few of you asked me “Does time go on the x-axis [of the graph]?” Since time always goes on the x-axis of a graph, I answered “Yes.” That may be true, but then I realized that’s not the question some of you really meant to ask. (The same thing goes with grocery shopping. You always remember why you went to the store after you get home.)
On this lab, you did not measure time nor are you to graph time. You measured period and period is not time.
Gotta fix things now? Remember – no erasure marks, no scratch outs and no white-out. Just draw a single line through your mistake. Like this. You can find graph paper on the web easy enough.
Here are pictures from the board for today’s lab:
And yes, I added a question to the top and forgot to renumber them. There are four questions.
Just got this in an email:
Due to unforeseen circumstances, report cards will not be distributed on Wednesday, January 11th and there will be no homeroom on this date.
Homeroom after 1st will be scheduled for Thursday, January 12th, and report cards will be distributed on this date.

Here are today’s physics notes. This includes the problems we didn’t get to, so it’s a good thing to go over. Don’t forget to get the 2nd semester class policies signed and returned by next Friday! (And sign up for Remind101.com if you haven’t already.)
