Physics Screencasts - How to Videos for AP Physics

Below are links to specific “How To” videos that are relevant to AP Physics, and are on my class blog. These show how to think about certain topics, and how to do certain problems. It has a voice-over and screencast from my tablet computer, so it is similar to being in class as we model how to do certain problems. These can be useful if you were gone the day we covered the topic, or need more examples with explanations, or want to review things from class prior to quizzams.
