1.     What forces act on the two carts as they interact during a collision?

2.     What is Newton’s third law prediction for the processes studied?

3.     Which cart experiences more force when one of them starts the process at rest?

4.     Which cart experiences more force when both carts are moving and have unequal masses?

5.     What is the overall effect of the cart’s velocity on the measured force, and on the relation between the pairs of forces studied?

6.     What is the effect of the mass of the carts on the relation between the pairs of forces studied?

8.     What sources of error can you identify in this experiment?
