Kinetic Energy = ½mv2
(m=mass v=velocity)
Mechanical Energy = PE + KE
(PE= potential energy KE= kinetic energy)
Chemical Energy = ????

Next to or underneath your graph answer the following prompt.
•Using your averages describe the outcome of your PACE experiment.
•In one or more of the trials was there a time where the data seems off or inconsistent. Circle it, or star it.
•What might have happened during that event? Explain.
