AP Physics Final Exam Study Guide Updated 12/9/2017

12/9/2017    STUDY GUIDE

AP Physics Students:  The final exam will be based on

1)  The Chapter 7 "Work and Energy" homework problems which have solutions posted in the AP physics moodle.

2)  Packet 9.1, which has solutions posted in the regular physics moodle.

3)  Examples from Chapter 7

4)  Review problems which I list below:


Review problems:  I need you to attempt them by Monday.  We will go over whatever problems give you 

trouble.  I have provided answers for you to check.   Note that I wrote the scientific 

notation in "E" style.  Don't do that in your work.
