PhysicsLAB: Summary: Graph Shapes for Constant Velocity

traveling at a constant speed in a positive direction
position-time s-t	velocity-time v-t	acceleration-time a-t

On all of these graphs, notice that

the slope of the position-time graph "equals" the height of the velocity-time graph
the slope of the velocity-time graph "equals" the height of the acceleration-time graph

Also note that the first two position-time graphs, shown immediately above and below, could have been drawn in either quadrant since:

quadrant I represents motion in a positive location
quadrant IV represents motion in a negative location

traveling at a constant speed in a negative direction
position-time s-t	velocity-time v-t	acceleration-time a-t

If requested, the rectangular areas on the velocity-time graphs bounded by the horizontal "blue" graphs and the x-axis "equal" the object's displacement during that time interval. The displacement would be positive if calculated in quadrant I and negative if calculated in quadrant IV. The displacement can also be calculated as the difference in the heights on the position-time graph for the same interval of time.
