Resources

Websites that are useful:

http://www.physicsclassroom.com/

-- Great introductory material and interactive sections; I would maybe go through the tutorial here before reading the pages in the textbook.

http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html

-- Good stuff here, but can be a little intimidating.

http://physics.bu.edu/~duffy/py105.html

-- Good information here, but not very many diagrams and illustrations.

https://phet.colorado.edu/

-- Great place for online physics simulations. You are able to manipulate variables and visually see the outcomes. Its a great website for testing your predictions.
