Find out about a skate boarder and design a skate park on Energy Skate Park simulation.
Issues to investigate:
- What is mass?
- Does the weight of the skater influence his/her speed?If yes, how?
- How does the size and weight of the skater influence the total energy?
- What does the bar graph tell you about energy?
- Use the bar graph to find out what is meant by kinetic energy and potential energy?
- The skater continues endlessly? How is this possible? Is this realistic? Why/why not?
- What does friction do?
- What kind of energy is related to friction?
- Does friction have (1) a larger, (2) a smaller, or (3) the same impact on a big skater than on a small skater?
- Match the concepts in the first column with the correct sentences in the second column.
|1. speed||A. When the skater is at the top of the track …… energy is highest.|
|2. friction||B. The skater’s weight does not influence the speed.|
|3. mass||C. When still moving the skater has ………… energy.|
|4. kinetic energy||D. The skater is moving faster in the beginning.|
|5. potential energy||E. On a smooth track the skater will go faster.|
|6. thermal energy||F. At the end of the skating tour all energy has been tranferred into heat.|
For correct answer to question 4 see bottom.
- Design a skate track whereby the skater makes a salto and does not fall off the track.
- Present the skate track to your classmates and explain what you have done to reach your goal.
