Test 1 for Design 3

Test 1-


Hypothesis:
If thread is used to pull back the hanger attached to the mousetrap, then it will unwind at an even pace.

Procedure:
  1. Cut appropriate piece of thread
  2. Tie thread through hook attached to hanger
  3. Pull back thread and attach to axle
  4. Wind the axle
  5. Let go of axle allowing the car to accelerate.
Results:
As the thread was released, it unwounded slowly. As the thread was unwinding, it got tangled which caused the vehicle to slow down.

Conclusion:
The results showed that the hypothesis was incorrect. The thread did not unwind at an even pace causing it to tangle. The acceleration, therefore slowed down. This experiment shows that thread should not be used in the vehicle. Fishing wire is the better choice.
