The problem:
A graph is constructed representing velocity vs. clock time for the interval between clock times t = 5 seconds and t = 13 seconds. The graph consists of a straight line from the point (5 sec, 16 cm/s) to the point (13 sec, 40 cm/s).
What is the clock time at the midpoint of this interval?
answer/question/discussion: 9 seconds
What is the velocity at the midpoint of this interval?
answer/question/discussion: 28 cm/s
How far do you think the object travels during this interval?
answer/question/discussion: At an average rate of 28 cm/s and traveling for 8 seconds it would be 224 cm
By how much does the clock time change during this interval?
answer/question/discussion: change is 8 seconds
By how much does velocity change during this interval?
answer/question/discussion: change is 24 cm/s
What is the average rate of change of velocity with respect to clock time on this interval?
answer/question/discussion: 24/8 = 3 cm/s/s
What is the rise of the graph between these points?
answer/question/discussion: 24
What is the run of the graph between these points?
answer/question/discussion: 8
What is the slope of the graph between these points?
answer/question/discussion: 3
What does the slope of the graph tell you about the motion of the object during this interval?
answer/question/discussion: That it is increasing in speed at 3 cm/s/s
What is the average rate of change of the object's velocity with respect to clock time during this interval?
answer/question/discussion: It is increasing at 3 cm/s/s
