Question

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

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 (action), the second object will push back (reaction).

• The first option is incorrect because objects don't always stop moving after a collision. For example, in an elastic collision, they might keep moving.
• The third option is wrong as not all collisions result in bouncing off. In inelastic collisions, objects might stick together.
• The fourth option is incorrect because the second object might not start moving if it has a very large mass. For instance, if a small ball hits a massive wall, the wall doesn't start moving.

Answer:

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