11. Calculate the percentage of energy turned into heat using
.
12. Where did most of the energy go?
13. Repeat steps 3-12 with twice the number of balls and one-half the number of balls.
14. How does the temperature and potential energy (PE=mgh) change when you change the
number of balls? Why? Explain your results.
