Energy Skate Park Open the attached link to discover the changes in energy as the boy skating up and down the skate park, then answer the following questions. At which position does the boy have the highest potential energy? Both A and C At which position does the boy have the highest kinetic energy? None Change the boy mass to large and small using theMass Button, and discover how both kinetic and potential energy can change.Choose the correct answer: When the boy has small mass, he has high potential and kinetic energy. When the boy has large mass, he has high potential energy and low kinetic energy. When the boy has large mass, he has high potential and kinetic energy. Look at the bar graph shown in the picture. What is the wasted energy did the boy lose while skating? Thermal energy Potential energy Kinetic energy You went to a store to buy a light bulb. The diagram bellow shows the efficiency of the light bulbs the store has. Would you buy it? Yes, I would buy it. The light bulb is efficient. No, I wouldn't buy it. The light bulb is inefficient. Hooke's Law - Open the link.- Choose energy simulation.- Stretch the spring and observe how energy can change.- Answer the following question. Choose two correct answers about the spring energy. The more it is stretched, the more energy it has. The more it is stretched, the less energy it has. The stretched spring has elastic potential energy. The stretched spring has kinetic energy. Match the correct answer. Chemical Energy It can be stored in food and fuels. Light Energy It cannot be stored but it travels from one place to another. Electrical Energy It cannot be stored and it can be produced by batteries.
