Slow Restart Skater Energy Skate Park X X PI n this setup, your Initial Position is taken as the reference line where Position and Gravitational Potential Energy are 0 (or very close to it given measurement uncertainty). Set the simulation up so you have the correct reference. Now move the reference bar up so that the recorded position (pink dot) you've chosen is on the next horizontal line. Record the Position and Potential Energy. Move the reference bar back to the initial position and repeat the previous steps but move the reference bar down. Once you've recorded those values, change your initial position (reference bar does not start on the chosen recorded position) and move the bar either up or down 1 horizontal line. Fill out the table below (note: make sure to
