Take a moment to answer these questions.
- How can you measure how fast you're walking?
- How can you measure or calculate the energy of an object in motion?
- Which type of energy is that?
Build a pedometer!
We will use it to measure your steps and how fast you can walk.
- Done, I have build my pedometer
Practice measuring your steps.
- I've programmed my pedometer.
- I've walked 10 steps to try out my program.
- I've imported the data into my graph.
- I can answer this question:
- How can you identify individual steps in your graph data?
Adjust your program to detect your steps.
- I've found threshold values by looking at my first experiment graph.
- I've adjusted and tested my program.
Convert your steps into a unit of speed, and then kinetic energy.
- I've converted my steps into speed (distance/time).
- I've walked slowly and then faster to see the change in speed.
- I've converted my steps into kinetic energy (½mv2).
Spend more time exploring.
- I've found a cool way to display energy levels!
How did you do?
- How would you summarize your experiment?
