Answer:
The balloon car is a good model of Newton's third law.
Explanation:
Newton's third law establishes that for every action or force, there is an equal and opposite reaction.
As the air in the balloon is released, an equal force provokes the car to move in the opposite sense, but in the same direction. These forces are equal in terms of magnitude because for every force of action, there is a force of reaction. For example, if a roller skater pushes another roller skater, they would both move in the same direction, or line, and the force produced will be the same for each one.
This is what a vector is. An object that has both a magnitude (force) and direction. Now, the difference between sense and direction is that if two objects are moving in the same line: they share the same direction. But, if one is headed north and the other south, they are moving in the opposite sense.
