- 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’ll use it to measure your steps and detect how fast you’re walking.
- Done! I’ve built my pedometer.
Practise measuring your steps.

- I've programmed my pedometer.
- I've walked 10 steps to test my program.
- I've imported the data into my graph.
Answer This Question- How can you identify the individual steps in your graph data?
Adjust your program to detect your steps.

- I've found the threshold value to detect each peak on the graph.
- I’ve put in the threshold value in the variable.
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 summarise your experiment?
Brilliant!
