1. Newton's third law describes force __.
2. Which example best shows an action-reaction pair?
3. Match the situation to the main idea: rocket launch
Match with:
Answer:
4. Gravity is an attractive interaction between __.
5. Why can two colliding objects experience equal interaction forces but still have different motion changes afterward?
6. Which design goal best fits crash safety?
7. A satellite curves around Earth because gravity keeps changing its __.
8. Why do scientists use evidence from motion data when arguing about forces?
📋 Teacher Answer Key
1. pairs
2. A swimmer pushes water backward and the water pushes the swimmer forward
3. gas is pushed downward and the rocket is pushed upward
4. masses
5. Their masses can differ, so the same interaction can produce different changes in acceleration and motion
6. spread the collision over time and distance to reduce harmful motion changes
7. direction
8. The data show how motion changed, which helps support claims about the forces and interactions involved
