For an object slowing down, like a skateboard or a curling rock:

  • What does the graph showing distance over time look like ?
  • What does the graph showing speed over time look like?
  • What does the graph showing kinetic energy over time look like?

Build a street curling rock!

  • Done! I've built my street curling rock or freewheeling vehicle, or call it how you like!

Practice your push.

  • I have a starting line and a target.
  • I can push my curling rock toward the target and trace a graph.

Get your Initial Speed.

  • I've changed my program to get my initial graph speed.
  • I've tried a new push of my curling rock and I can log an approximate initial speed.

Find the initial kinetic energy.

  • My program is calculating and showing the kinetic energy at the beginning of my push.

Let's play a game!

  • I've prepared the playing field.
  • I've tried to hit the middle of the target 3 times.
  • I've measured the distance between the target and where the rock stopped.

How well did you do?

  • I can answer these questions:
    • How would you summarize your experiment?
    • What have you learned?

Looking good!
