speed is increasing over time

speed is decreasing over time

speed is constant over time

the object has stopped moving

12 meters

6 meters

3 meters

not enough information to tell

speed is constant

distance is constant

the direction of motion stays the same

speed slowly increases over time.

speed is increasing at a constant rate (constant speed)

the motion of the object is decreasing at a constant rate
(slowing down at constant speed)

the object is maintaining its direction of motion

the object is returning to where it started

Only the speed will change

Only the direction will change

Speed and direction could both change

neither speed or direction will change.

Because the net force was 5 N in Al's direction

Because the net force was 20 N in Al's direction

Because the force was 15 N in Ted's direction

Because the force was 5 N in Ted's direction

the push on each side must be equal

The push on one side must be larger than the other side

both forces must make the net force zero

both forces must make a net force so that the object remains in one place.

gravitational force must be ignored

all the forces on the object must be measured

only the force pulling upward needs to be measured

only the distance over which the object is lifted by the pulley must be measured
