The problem:
A ball is moving at 10 cm/s when clock time is 4 seconds, and at 40 cm/s when clock time is 9 seconds.
*
Sketch a v vs. t graph and represent these two events by the points (4 sec, 10 cm/s) and (9 s, 40 cm/s).
answer/question/discussion: ->->->->->->->->->->->-> scussion:
* I have recorded this in my notebook.
Sketch a straight line segment between these points.
answer/question/discussion: ->->->->->->->->->->->-> scussion:
* I have sketched this line.
What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
* Rise - 30
Run - 5
Slope - 6
What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> scussion:
The area beneath the graph represents what the velocity change could be if its slope or average change was lower. As far as I can see, it is irrelevant to the current segment.

Rise, run and slope have units, which need to be included and which are important for interpretation.
The area also has units, which can help guide the interpretation.
