Final Exam Guidelines

1.Bring pencils, paper, calculator, and something to do quietly when you are done.  For this class you may also use a 4" x 6" (max size) note card with notes on both sides.  Remember that it needs to be hand-written and will be collected at the end of the test.

2.Go to restroom BEFORE the test!  No bathroom passes until after you are done, and then 1 at a time

3.NO CELL PHONES OUT PERIOD!!  Bring something else to do.

4.No talking until EVERYONE is finished.  This is basic courtesy to your classmates.

5.Cheating on any part of the test will result in a zero.  Don’t do it!

Finally, get enough rest, eat healthy food, and try not to stress too much about the test.  You will be okay!

Quick Lab: Is Energy Conserved? Due Thur/Fri 1/10-1/11 (can turn in Mon 1/14 on time)

Drop 2 different masses (coins) from 2 different heights and determine if energy is conserved. (that makes 4 conditions total)

1.  Make a neat, labeled data table: What do you need on it?

2.  Collect data (5 trials each:  then calculate average and uncertainty for trials)

3.  Do calculations: Vf, Pei, KEf (show work for 1 sample of each type)

4.  Is energy conserved?  Compare numbers directly and give reason for your answers.

5.  Discuss factors that contribute to uncertainty in data (solid paragraph).

The Week of 1/7-1/11

• Mon 1/7/13:  Check off Problems 7-11 and go over.  Conservation of Mechanical Energy.  HW problems 12-16 for Tues/Wed, although you will get time to work on them.
• Tues/Wed 1/8-1/9:  Questions on Homework?  Work time.  Work-Kinetic Energy Theorem.  Do problems 17-19.  Quick Lab:  Is Mechanical Energy Conserved?
• Thurs/Fri 1/10-1/11:  Check off Probs 12-19 and go over.  Turn in Energy Conservation Quick Lab. What is Power?  Run the stairs and calculate your power.  HW probs 20-23.

Happy New Year! The Week of 1/2-1/4
