Here are some resources to help you with Work, Power, and Energy (Chp 6 in your textbook):
1. http://www.physicsclassroom.com/Class/energy/ - Great web site for physics. Explains the concepts in easy to understand terms.
2. http://ia301512.us.archive.org/0/items/AP_Physics_B_Lesson_07/Container.html - video on the Work-Energy theorem
3. http://www.learnapphysics.com/apphysicsb/work_and_energy.php - practice problems (with solutions), and links to video lessons.
Don't forget that your practice kinematics test is due on Monday and you will have your open book quiz on Chp 6 Monday also.
