Test 3 for Design 3

Test 3-


Hypothesis:
If the balloon is used as a rubber band around the wheels (Cd's), then there will be greater friction.

Procedure:
  1. Cut top and bottom of balloon off.
  2. Cut that in half
  3. Stretch "rubber band" around each wheel (Cd)
  4. Repeat steps 1-3 for the other set of wheels
Results:
A forward force was neccisary to make the vehicle move. As well as, compared to before the vehicle did not accelerate as fast and didn't go as far.

Conclusion:
While the rubber bands did indeed create friction, it caused the vehicle to slow down excessively. The hypothesis was proven correct; however, the balloon rubber bands will have a negative impact on the vehicle. Therefore, the balloon rubber bands will not be used on the vehicle.
