1. Open the PHet simulation:Energy Forms and Changes link: ( https://phet.colorado.edu/sims/html/energy-forms-and-changes/latest/energy-forms-and-changes_en.html ) and the "Systems" tab. Be sure to click the box with "energy symbols" so you can see the energy types
2. Arrange the simulation to create each of the different configurations pictured below. Then, run the simulation for at least 30 seconds.
3. Describe what occurred and then name the transformations that you saw

Configuration

Questions:

1. Why did you have to feed the biker?
2. There are 5 forms of energy in this simulation, but we discussed 9 in class
   1. Which 4 are missing?
   2. Of those 4, should any of them be included in this simulation? Explain why/why not.
