Unit 4 Energy Go to the Energy Skate Park simulation website from the link in the Unit Lesson Unit 4. Click the image and Press the run arrow to start the simulation. You should see three windows, “Intro”, “Friction” and “Playground”. Explore the siteand familiarize yourself with the controls, then select INTRO for questions 1,3, and 4 below. Run several simulations and answer the following:1.Does the skater hit the same height on both sides of the track for a dish shaped track? (Check Show Grid to aid in this answer). 2.If you select the “Friction”screen, how does the skater’s motion change? 3.Go back to INTRO, and turn on the energy Pie Chart & Bar Graph. Note the colors of the Potential and kinetic energy components on the graphs, pausing if needed.a. At what point of the track does the skater have the highest kinetic energy(be specific please)? At the very middle of the ramp b. Highest Potential energy? At the very top points of the graph c. At what point of the track does the skater have the lowest kinetic energy At the very top points of the graph d. Lowest Potential energy? The very middle of the graph 4.Did the TOTAL energy change at any point? The total energy stayed the same at every point of the ramp. 5.Go to PLAYGROUNDand construct a loop the loop track to have at least onecomplete loop between start and finish. What must you do in order to insure that the skater completes the loop without falling? Extra credit (5 points) –Include a screen shot of your track including the loop.
The ramp must be very steep for the skater to get enough speed to make it through the loop without falling.
