The Skate Basic Park – Intro to Energy Potential and Kinetic PhET Lab Introduction: When Tony Hawk wants to launch himself as high as possible off the half-pipe, how does he achieve this? The sk ate park is an excellent example of the conservation of energy. The law of conservation of energy tells us that we can never create or destroy energy, but we can change its form. In this lab, we will look at the conversion of energy between gravitational-potential energy, work, and kinetic (or moving) energy. Use the internet, your textbook, or notes to define the following key terms: Kinetic Energy _ motion._ Potential Energy _ Mechanical Energy _ Joule _ State, in your own words, the Law of the Conversation of Energy. _ Procedure: PheT Simulations  Play With Sims  Physics  Energy Skate Park: Basics Take some time and play with the skater. Turn on the Bar Graph, Pie Chart, and Speed options. How does increasing skater's mass change the skater’s…. Kinetic Energy? _ How does the skater’s kinetic energy change as he moves down the ramp? _ How does the skater’s kinetic energy change as he moves up the ramp? _ How does the skater’s potential energy change as he moves down the ramp? _ How does the skater’s potential energy change as he moves up the ramp? _ How does the skater’s total energy change as he moves down the ramp? _ How does the skater’s total energy change as he moves up the ramp? _ Describe the skater’s kinetic energy at the bottom of the ramp. _ Describe the skater’s potential energy at the bottom of the ramp. _ What happens when the skater is dropped onto the ramp from above the ramp? _ Observe the following situations. Draw the possible bar graphs for the situation shown. Compare your results with a nearby lab group, AFTER you have completed this section. Draw where the skater might be based on the bar graphs shown. Compare your results with a nearby lab group, AFTER you have completed this section. ← Consider this zany track. What point or points on this track would the skater have ... The most kinetic energy? The most potential energy? The same kinetic energy (two points) and Conclusion Questions: (circle the correct answers) 1. At the highest point kinetic energy is zero / maximum while the potential energy
