Read the following case and answer the following questions:
A space research organization launches a rocket into space. During launch, the rocket engine burns fuel and releases hot gases downward at very high speed. As the gases move downward, the rocket begins to rise upward. Scientists explain that this motion is based on Newton’s third law of motion. Even after leaving Earth’s atmosphere, the rocket continues to move in space.
1. Which law of motion explains the rocket launch?
2. Identify the action force in this situation.
3. Identify the reaction force in this situation.
4. Why can rockets move even in outer space where there is no air?
5. A student says:
“Since action and reaction forces are equal and opposite, they should cancel each other and the rocket should not move upward.”
Which statement best explains why the rocket still moves upward?
