Question

A) Two postal delivery workers have different routes. They both travel from the post office, to
neighborhoods to deliver mail, and then back to the post office. Which statement must be true about the
two postal delivery workers? (1 point)
They each have a displacement of 0 miles.
They have the same velocity.
They travel the same distance.
They each travel a distance of 0 miles.

A) Matt is walking at 1.25 miles per hour to the east. Jaime is walking at 1.25 miles per hour to the
south. Which statement describes the movement of Matt and Jaime? (1 point)
They have the same speed but different velocities.
They have the same speed and the same velocity.
They have different speeds but the same velocity.
They have different speeds and different velocities.

A) What does a horizontal line on a position-time graph indicate about the object? (1 point)
The object remains still.
The object has a constant, nonzero velocity.
The object has a position of zero.
The object is accelerating.

A) A force acts on an object. Which option describes an action that could prevent the object from
moving? (1 point)
a force applied in the same direction with a greater magnitude at the same time
a force applied in the opposite direction with the same magnitude at the same time
a force applied in the opposite direction with a greater magnitude at the same time
a force applied in the same direction with the same magnitude at the same time

A) Which option is the force with the greatest magnitude? (1 point)
the force needed to lift a hairbrush
the force needed to lift a pencil
the force needed to lift a chair
the force needed to lift a textbook

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