The skate 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 Energy Skate Park: Basics 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: Bar Graph Pie Chart Kinetic Energy Grid Potential Energy Speed Skater Mass Mechanical Energy Small Large Joule State, in your own words, the Law of the Conversation of Energy.

How does the skaters kinetic energy change as he moves up the ramp? How does the skaters potential energy change as he moves down the ramp? How does the skaters potential energy change as he moves up the ramp? How does the skaters total energy change as he moves down the ramp? How does the skater's total energy change as he moves up the ramp'.7 Describe the skater's kinetic energy at the bottom of the ramp. 9) Describe the skaters potential energy at the bottom of the ramp. 10) What happens when the skater is dropped onto the ramp from above the ramp? 19:36 \\ 12min Physics assignment v 11) Consider this zany track above. What point or points on this track would the skater have The most kinetic energy? E The most potential energy? |:| The same kinetic energy (two points) |:' and El PHYS 1046 Conclusion Questions: (circle the correct answers) At the highest point kinetic energy is zero / maximum while the potential energy is zero / maximum. At the lowest point kinetic energy is zero / maximum while potential energy is zero I maximum. Mass affects / does not affect the amount of energy. As an object falls in gravity. kinetic energy increases / decreases / remains the same. As an object falls in gravity. potential energy increases / decreases /remains the same. As an object falls in gravity. total energy increases / decreases/ remains the same. An object travelling faster and faster has a kinetic energy that increases / decreases / remains the same. An object travelling faster and taster has a potential energy that increases / decreases / remains the same. As an object speeds up. the total energy increases / decreases / remains the same. 10. As an object slows down. the total energy increases/ decreases / remains the same. Evalu eria Mark Procedure Questions 20 Points Conclusion Questions 10 points
