Video is called PhET Skater Park Energy Lab ( Mark Blachly) Part 1 (5 Points): Accomplish as described in the video and for the heights of 6m, 5m, 4m, 3m, 2m, 1m, and 0m calculate the potential energy, report the speedometer speed, calculate the kinetic energy, and add up and report the total energy?. Your answers could be in the form of an organized list like this: At 6 meters: PE= 3600 J Speed = ... KE = ... Total Energy = ... At 5 meters: etc... Part 2 (5 Points): New Set Up of Simulator: Take the simulator from Part 1 and make the following changes: Move the friction slider over to about half way. Turn on the energy bar graph Part 2 Questions: 2.1 Start the skater off at 6 m like in Part 1 but notice that there is another form of energy being considered. Why is it that thermal energy was not important for part 1, but thermal energy is important for the setup of part 2? 2.2 Run the simulation a few times in order to determine when is the conversion of mechanical energy into thermal energy the fastest? Note that you can use the 'Restart Skater' button to perform this idea . 2.3 Compare and contrast how energy is conserved in the two simulations
