January 2023 ScienceScene.com PHSA 1050 Topic 6 In Class Name Date Introduction: When a skateboarder wants to launch themselves as high as possible off the half-pipe, how do hey achieve this? The skate park is an excellent example of the law of 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 virtual lab. we will look at the conversion of energy between Energy Skate Park: Basics gravitational-potential energy, work, and kinetic (or moving) energy. Use the internet, your textbook, or notes to define in simple terms the following key words: M Bar Graph 1. Kinetic Energy M Pie Chart 2. Potential Energy Grid Speed 3. Mechanical Energy Skater Mass 4. Joule Sma Large 5. State, in your own words, the Law of the Conversation of Energy. Procedure: Run the PHET Energy Skate Park: Basics Run Now! simulation. Click on INTRO. Take some time and play with the skater. Turn on the Bar Graph, Pie Chart, and Speed options. Become familiar with the orange ' Reset' button on the right and how to change the speed of the simulation with the buttons on the bottom. Pie Chart O Bar Graph Grid Speed Mass Slow Motion 1! > Normal PhET How does increasing skater's mass change the skater's.... (highlight or circle one of the choices) 6. ...Kinetic Energy?
