Review: APC 1993 & 1994 FR
1. Individual students will put a single problem on the board for homework credit.
2. The student putting the problem on the board will then present the problem to the class answering all questions and emphasizing the physics of the problem [15 pts]
3. All other students will submit one randomly selected problem for homework credit [15 pts]
Assign: 1994 FR & 1988 MC for NEXT Friday, Mar 19.
Important Reminder! All Answers in the multiple choice test MUST be accompanied by clear justification! No reason, no credit!
 
The primary goals this week will be to: Continue the study of Simple Harmonic Motion; Begin AP Review - see below!
