8/26/10:what we did is we made our car move well not really move because when we tried to make the car move with the balloon it did not really move. sometimes it will move but not very far so that means the balloon is to weak or the car is to big. it relates to  newtons second law because the air in the balloon is not enough force to push the car (the mass) and make it move and accelerate. This explains how something times zero equals zero. If the acceleration was zero and the mass was about 75g then 0 X 75=0 because if your multiplying something by nothing you won't get anything.
