List of all How To Videos

Below are links to specific “How To” videos that are relevant to 3 and 4 Chem-Phys. These show how to do certain key problems in AP Physics. Each is a voice-over screencast using Doc V’s 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. Note that those videos that are shown as 'On YouTube' are updated and can be viewed. The latest screencasts are made using Screencast-O-Matic (very easy to instantly use).

ActivPhysics
This site is setup for our textbook, University Physics, and has hundreds of computer simulations/experiments that are designed for student use.  It asks questions and for you to make predictions, and then check with the simulation to see if you are correct.  It is a good option if you want to get visuals in your head about a topic.  There are animations showing the actual physical system being discussed, slider bars to vary the values of different parameters of the system, graphs of data in real time so you can see what happens with the system, and so on.

Interactive Physics
Interactive Physics is software where you can design and create your own simulations; mostly for mechanics, but there are some E&M topics you can also work on. This is on school computers.
