Equations! (Download and run as a slide show for it to work properly)
If we had time, we used a problem solving method to do some more problems together.
We are doing a lab next week for which a long exposure (~1.5 seconds) camera is needed. Please check your cameras/phones for that ability (is there an app for that?).
Homework is Ch. 2 Problems 26, 27, 28, 31.
