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).
