Stage: 2 Challenge Level: Challenge Level:1
You can use the interactive environment to explore lots of different ideas including:
  • how cogs turn relative to each other

  • the relationship between the number of teeth on a set of different cogs and full turns

  • how cogs mesh together (how often does the same tooth go into the same gap?)
