• decreasing

Which statement indicated the motion has occurred?

• The reference point has changed
• the position of the object has changed
• the object being describe has changed

What can you tell about the motion of an object represented by a curved line on a distance-time graph?

• the object is not moving
• the objects speed is not constant
• the object is moving at a constant speed
• none of these

if two objects are represented on a distant time graph, which object is moving faster?

• the object represented by the longest straight line
• the object represented by the shortest straight line
• the object represented by the steepest straight line
• the object represented by no line

Which situation would be indicated by an acceleration arrow and a final velocity arrow pointing in the same direction?

• an object speeding up
• an object at a standstill
• an object slowing down
• none of the above
