How does a balloon-powered race car apply to Newton's laws of motion?

Answer 1

First, you have to know the 3 laws of motion. 1."A body continues to maintain its state of rest or of uniform motion unless acted upon by an external unbalanced force." 2."F = ma: the net force on an object is equal to the mass of the object multiplied by its acceleration." 3."To every action there is an equal and opposite reaction." To prove the 1st law, you can see that the air released from the balloon disturbs the state of rest of the car and makes it move. To prove the 2nd law, you need the exact measurements, so I can't help you. To prove the 3rd law, you can see that as the air in the balloon is released, the car moves. So, as the amount of airflow increases, the distance the car moves increases. So, they are dependent on each other. How much air is released determines the distance the car moves. Moreover, as the air shoots out in a direction, the car will move in the other direction.
