Describing Motion

Reference point, distance, and direction is needed to describe

• average speed

• position

• displacement

• velocity

Total distance traveled divided by the total time it took to travel that distance is

• constant speed

• displacement

• position

• average speed

Speed at a specific point in time is

• displacement

• instantaneous speed

• average speed

• motion

Process of changing position is

• motion

• average speed

• constant speed

• displacement

An object's distance and direction from a reference point is

• reference point

• speed

• position

• velocity

Distance between the initial and final position of an object

• position

• velocity

• speed

• displacement

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

• constant speed

• instantaneous speed

How do you know that motion has occurred?

• The object has not changed.

• The reference point has changed.

• The object being described has changed.

• The position of the object has changed.

How can you tell which object is moving faster on a distance-time graph?

• By the longest straight line

• By the steepest straight line

• By the shortest straight line

• By the line that is most curved.
