Question

according to newtons third law of motion, which statement is always correct? (1 point)
if two moving objects collide, then they will bounce off each other.
if a moving object hits another object, then the second object will start moving.
if two moving objects collide, then both will stop moving.
if a moving object hits another object, then the second object will push back.

Explanation:

Newton's third law of motion states that for every action, there is an equal and opposite reaction. When a moving object hits another object, the second object exerts a reaction force (pushes back) on the first object.

• The first option is incorrect because objects may not always bounce off each other (e.g., in inelastic collisions).
• The second option is incorrect as the second object may not start moving if it has a large mass or if external forces prevent its motion.
• The third option is incorrect as objects do not always stop moving after a collision (e.g., elastic collisions where they keep moving).

Answer:

If a moving object hits another object, then the second object will push back.
