Analysis Questions 1-3

1. Newtons First Law of Motion states that a object will stay in motion unless acted upon by an outside force, and an object will stay at rest unless acted upon by an outside force. Our Balloon Car followed Newtons Law because the outside force was friction. The car came to a stop because the friction was higher that the force produced by the balloon. The balloons force was higher that the force of friction at the beginning, but it later was not.

2. Newtons Second Law of Motion states that the more mass an object has, the more force it will take to put it in motion. With our balloon car, the force the balloon created was more than enough to push the car at the start. It had enough to accelerate the car. Towards the end, when the balloon had no more air, the car slowed down.

3. The concept of momentum states that the more mass or velocity an object has, the harder it is to stop. A 18 wheeler is going to be harder to stop than our balloon car, but against air resistance our car still had force to break through. The velocity our car was going was greater than the force of air resistance, which meant that our balloon car could travel a little bit farther, even after the balloon had run out of air.
