Friction
A balloon powered car is moves because the balloon pushes out air. Whenever something exerts a force on something else (in other words, the balloon is exerting force on the air), then the object being pushed always exerts an equal and opposite reaction force on the object exerting force on it (in other words, the air exerts force on the balloon). Because the balloon is attached to the car, when the balloon is pushed by the air, the car is pushed. The law that for every force there is an equal and opposite reaction force is Newton's Third Law of Motion.
If the car is lighter, Then the balloon powered car will go further.
There was no ballon powered car.
It is a toy car built from Lego's and it is balloon powered.
No
The more balloons you have, the more the force will be to move forward. So yes. btw there are a lot of balloon car websites. I have just recently made a balloon car myself and won farthest distance.
