Below is an essay on "Newtons Law" from Anti Essays, your source for research papers, essays, and term paper examples.

Newton’s law states that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an unbalanced force. My car demonstrated Newton’s first law; the law of inertia, because it was at rest until I acted on it with an unbalanced force. The balloon was   the unbalanced force, which caused the car to accelerate. If I had just   put the car down on a flat surface it wouldn’t have moved. But since I filled up the balloon and released that air after I put the car down it moved because it is being acted on by an outside force. It would have kept on rolling without an outside force; rolling friction. If it was not for rolling friction, the wheels would not have slowed down and the car would roll on forever unless something got in its way.
Newton's second law states that force=mass x acceleration. The mass is the car and the acceleration is the balloon/air. If I had added more weight to the car it would have slowed down the acceleration. Also, the less air I blow in the balloon, the smaller the force it applied to the car would be; which would cause the car to move slower.
Newton's third law states that for every action there is an equal/opposite reaction. I demonstrated this law with my car because the action was air rushing out from the balloon, and the reaction was the car accelerating. The two are dependent because as airflow increases , the cars distance increases. Also , as the air comes out in one direction, the car accelerates in the other direction (equal but opposite).
