Air Cart Further Investigations

  • What slows the cart down? Investigate ways to reduce the friction of your cart. Your cart should use the SmartWheel, but anything else about it can be changed. Provide reasons for your design choices. Which changes will have the greatest decrease in friction?

  • Decide on a way to compare the friction of different carts. Why is this a fair test? Compare various carts and see if you can understand what the differences are that make them have more or less friction. Do they test the same every time?

  • Play the sabotage game. Investigate ways to increase the friction of your (or your opponent's) cart.
