Which item is necessary to describe location?

• two dimensions

• a reference point

• a change in speed

When an arrow represents velocity, the length of the arrow is

• time

• speed

• direction

If an object speeds up, slows down, or changes direction, it experiences a change in

• mass

• velocity

• reference point

Distance and direction from a reference point

• displacement

• motion

• position

Process of changing position

• displacement

• motion

• position

Difference between initial and final position of an object

• displacement

• motion

• position

total distance traveled divided by the total time taken to travel that distance

• average speed

• constant speed

• instantaneous speed

speed at a specific point

• average speed

• constant speed

• instantaneous speed

Rate of change of position in which the same distance is traveled each second

• average speed

• constant speed

• instantaneous speed

Starting point describing the location of an object

• positive direction

• negative direction

• reference point
