According to Newton's third law of motion, the correct statement is:
C: If a moving object hits another object then the second object will push back.
Newton's third law states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another, the second object exerts a force of equal magnitude and in the opposite direction back onto the first object.
The other options do not universally apply:
- A is incorrect because the objects may not stop moving after a collision; they could continue moving, or one could stop while the other keeps moving.
- B is incorrect because not all collisions result in bouncing; some may result in sticking together, for instance.
- D is also not universally true, as the second object may not start moving depending on the forces involved (for example, if it is anchored or if the collision is inelastic).
Thus, option C accurately reflects Newton's third law.
