Answer Key for Common Activities
To assist students in maximizing their understanding of the Energy Skate Park, the following answer key provides guidance for common activities and questions associated with the simulation.
Activity 1: Exploring Energy Types
Questions:
1. What happens to the skateboarder's kinetic energy as they go down a ramp?
2. How does the potential energy change when the skateboarder reaches the highest point?
Answers:
1. As the skateboarder descends the ramp, their kinetic energy increases due to the conversion of potential energy into kinetic energy.
2. The potential energy is highest at the top of the ramp and decreases as the skateboarder moves downward.
Activity 2: Creating Your Own Track
Questions:
1. Describe how changing the height of the starting point affects the overall energy dynamics.
2. What track design results in the most efficient energy transfer?
Answers:
1. Increasing the height of the starting point results in greater potential energy, which converts into kinetic energy as the skateboarder descends.
2. A smooth track with gentle curves and minimal friction allows for efficient energy transfer, maximizing the distance traveled.
Activity 3: Investigating Energy Conservation
Questions:
1. Is mechanical energy conserved throughout the skateboarder's movement? Explain.
2. How does friction impact energy conservation in the simulation?
Answers:
1. Yes, mechanical energy is generally conserved in the absence of friction, as the sum of kinetic and potential energy remains constant.
2. Friction introduces energy loss, converting mechanical energy into thermal energy, which means that total mechanical energy decreases over time.
