According to Newton’s third law of motion, the correct statement is:
If a moving object hits another object, then the second object will push back.
This law states that for every action, there is an equal and opposite reaction. When one object exerts a force on another, the second object exerts an equal force in the opposite direction. The other statements are not universally correct. For instance, objects may not necessarily bounce off each other, both may not stop moving, and hitting an object does not always cause it to start moving (e.g., if a stationary object is immovable or very heavy).
