Newton's Laws of Motion Quiz

What does Newton's first law of motion state about an object at rest or in motion?

• It will always remain in motion.

• It will change its state only if an external force acts on it.

• It will change its state spontaneously.

• It will always remain at rest.

Which formula represents Newton's second law of motion?

• F = a / m

• F = m + a

• F = m / a

• F = m * a

According to Newton's second law, what happens when an external force is applied to an object with constant mass?

• The object's color changes.

• The object's mass increases.

• The object's velocity changes.

• The object's shape changes.

What does Newton's third law of motion imply about forces?

• Forces only act in one direction.

• Forces cancel each other out.

• Forces do not affect each other.

• For every action, there is an equal and opposite reaction.

In the context of Newton's third law, what happens when a ball hits a wall?

• The ball stops moving without any force exerted.

• The ball exerts a force on the wall, and the wall exerts an equal force back.

• The wall exerts a force only if it is made of brick.

• The wall absorbs the force completely.
