1. Use Newton's first law of motion to explain why your car began to move as well as why your car eventually came to a stop.
Newton's first law of motion states, an object in motion will stay in motion unless acted upon an outside force. Our car began moving because the balloon, a force, pushed it forward. The car kept moving because the outside force, the friction of the wheels, hadn't acted yet. Our car eventually came to a stop because the wheels created friction on the ground, which was the outside force.
2. Use Newton's second law of motion to explain how the mass affected the acceleration of your balloon car at the start.
Newton's second law of motion states, the net force of an object is equal to the product of its acceleration and its mass. This means that force and acceleration are directly proportional or, as one goes up so does the other. However mass and acceleration are indirectly proportion so as the mass goes up, the acceleration goes down. Our car was pretty heavy as balloon cars went and I noticed that it was very slow to start. It's because the matter in our car was very great resulting in a slower acceleration.
3. Please use the concept of momentum to explain how the mass and velocity affected your balloon car continuing to move after the balloon had run out of air.
Momentum is the product of an object's mass and velocity. Velocity and mass have to do with an objects inertia. Inertia is an objects tendency to stay at rest or keep moving. Our balloon car was moving so the inertia refers to its movement. Our car had a very large mass. Mass does not help acceleration...but it sure helps momentum. The reason our car kept moving a fairly far distance after the balloon was out was because our mass kept the momentum going.
4. Please use Newton's first law of motion to identify the action and reaction pair of forces that caused the initial forwards acceleration of your car, allowing it to leave the resting state.
Newton's third law of motions states, for every action there is an equal but opposite reaction. The reaction pair in our balloon car was the balloon and the car. The balloon blew out air behind the car. That caused an opposite (but equal) reaction resulting in pushing the car forwards with the same force the balloon was pushing out in the back.
