Assignment: Energy Skate Park In this assignment, you will construct a skateboard track that makes use of energy transformations. You will use it to investigate the relationships among kinetic, potential, thermal, and total energy. You will see how these energies change throughout the simulation and explore the transformation of gravitational potential energy and kinetic energy. Instructions Select the link below to launch the lab simulation required to complete this lab activity. It will open in a new window so that you can work through it while still having the instructions accessible. Energy Skatepark From the simulation home page, select the Intro activity, depicting a skater on a U-shaped track. When the simulation opens, look at the tool box in the upper right hand corner of the screen. At the bottom of the tool box, a slide bar exists that controls the mass of the skater. For this part of the activity, you want the mass to be moderate or somewhere between small and large. This is the default setting, so you do not need to move the slide bar. Click the speed box; a speedometer will appear. Place the skater at the top of the track and release him. 1. When does the skater have the most kinetic energy? How do you know this? 2. When does the skater have the most potential energy? How do you know this? 3. Select the bar graph. Explain what it shows and how it tracks the skater's energy. 4. Does the total energy bar change in the bar graph? Why or why not? 5. Explain how you would change the total energy of the skateboard/track system.
Select the friction tab along the bottom of the screen. You will have the same view as before, but you now have the option of adding friction. Initially it will be set at a medium amount. 1. Explore how friction affects the system. Discuss how friction affects the skater, his speed, and the graph of his motion. 2. Where is the force of friction the largest? Why? 3. Friction causes a loss of mechanical energy. Which energy is being produced? Assume that no friction is present and that the skater is moving at point A and stops at Point E on the opposite side. Complete the following chart with estimates of Gravitational Potential Energy and Kinetic Energy. Values have been entered for point A. А I Ω U D B Location Kinetic Energy (J) Potential Energy (1) A 50 100 B с D E
