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.
