INDIVIDUAL REPORT ANALYSIS

1. Analyze and comment on your calculated percent difference. 2. From this, is there systematic error in your measurements? 3. Why or why not? 4. What are the sources of your errors, and how could they be reduced? EXPANSION: Is friction a significant factor in this lab? To get an idea, calculate how much energy would be lost due to friction of the cart with the track using W=fiAx with fr = urn and compare this to the work done by the string. For this calculation you may use a typical value for rolling friction either from your text or the web.
