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’ll use it to measure your steps and detect how fast you’re walking.

  • Done! I’ve built my pedometer.

Practise measuring your steps.

Watch your steps - Lesson Header
  • I've programmed my pedometer.
  • I've walked 10 steps to test my program.
  • I've imported the data into my graph.

    • 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!
