A box is against a wall. A person pushes on the box, but the box does not move. Is this situation an example of a force?
(1 point)

No, this is not an example of a force because the box did not move.

O Yes, this is an example of a force because a force is a push or pull.

Yes, this is an example of a force because gravity is pulling the box down.

• No, this is not an example of a force because a force pulls an object.

In which situation would the momentum of a moving object increase? (1 point)

A force acting in the direction of the object's motion is removed from the object.

• Two forces of equal magnitude act on the object in opposite directions.

A force acting in the direction opposite the object's motion is removed from the object.

O A new force acts on the object, opposing the object's motion.
