I have completed a fairly extensive update to The Book of Phyz online. Changes and corrections made during the past school year are reflected. That translates to many new documents and many more corrected (previously available) documents.
The update applies only to Physics 1. I hope to be able to complete a similar update for AP Physics 2 next year.
Many presentations were added as Zipped QuickTime exports of Keynote files. That means you can play them on your computer, but you can't edit them.
The Book of Phyz is an extensive collection of handouts, demonstrations, labs, worksheets, and other documents organized by topic and posted as PDFs.
Physics teachers are free to use Book of Phyz materials in their classes for instructional purposes.
