2. A teacher sitting in her rolling chair pushes again the wall and moves in the opposite direction.


3. A model rocket flies upwards as the engine combusts and creates a force towards Earth.


4. A rollercoaster takes off quickly and everyone's heads are thrown backward toward the headrest.

Answer 1

1. First Law

2. Third Law

3. Third Law

4. First Law

5. Second Law

6. Third Law

7. Second Law

8. First Law

Step-by-step explanation:

Newton's first 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 outside force". Examples which include an object moving while other objects stay put will be an example of this.

Newton's second law is that Force is equal to Mass times Acceleration. Objects with larger masses will accelerate less compared to smaller masses if equal forces are applied.

Newton's third law states that "for every action, there is an equal an opposite reaction". If my hand applies a 30 N force to a wall, the wall will apply a 30 N force directly back to my hand. Anything involving equal forces being applied in two opposite directions will be an example of this.
