Define Potential Energy
Begin by defining potential energy in your own words within one concise eight word sentence:
Energy of a mass because of its position

Take a moment and Predict potential energy’s relationship to the indicated variables:
1. We tested the variable mass. As it was increased, the potential energy bar chart size increased (increased, decreased, or remained constant).
2. We tested the variable vertical distance. As it was increased, the potential energy bar chart size increased (increased, decreased, or remained constant).
3. We tested the variable horizontal distance. As it was increased, the potential energy bar chart size remained constant (increased, decreased, or remained constant).
4. We tested the variable speed. As it was increased, the potential energy bar chart size decreased (increased, decreased, or remained constant).
5. We tested the variable kinetic energy. As it was increased, the potential energy bar chart size decreased (increased, decreased, or remained constant).
6. We tested the variable total energy. As it was increased, the potential energy bar chart size increased (increased, decreased, or remained constant)

Define Kinetic Energy:
Begin by defining kinetic energy in your own words within one concise eight word sentence:
Energy gain by a mass from its motion

Take a moment and Predict kinetic energy’s relationship to the indicated variables:
7. We tested the variable mass. As it was increased, the kinetic energy bar chart size increased (increased, decreased, or remained constant).
8. We tested the variable speed. As it was increased, the kinetic energy bar chart size increased (increased, decreased, or remained constant).
9. We tested the variable potential energy. As it was increased, the kinetic energy bar chart size decreased (increased, decreased, or remained constant).
10. We tested the variable total energy. As it was increased, the kinetic energy bar chart size increased (increased, decreased, or remained constant).

Now that you have made some predictions, we are now going to explore the variables and concepts that contribute to the scientific definition of potential energy. Using your definition of potential energy, we will test the four variables that may or may not contribute to the size of the pie chart and potential energy bar.

Testing Potential Energy:
Select the Pause button so that the simulation does not moved when you let go of the skater. Begin testing the questions 1, 2, and 3. Explain how you tested each and what the result in the
