According to Newton's third law of motion, the statement that is always correct is:
**3. 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 a second object, the second object exerts an equal force in the opposite direction back on the first object.
The other statements can be false under certain conditions:
1. The second object may not start moving if it is fixed or there is enough friction.
2. The objects may not necessarily bounce off each other; they could stick together or deform.
4. They may not stop moving if their collisions are elastic or involve other forces.
Therefore, statement 3 accurately reflects the principle of action and reaction.
