A ball starts with velocity 4 cm/sec and ends with a velocity of 10 cm/sec.
What is your best guess about the ball's average velocity?
answer/question/discussion: ->->->->->->->->->->->-> sion:
(4 cm/s + 10 cm/s)/2 = 7cm/s
This is a simple average of the velocities.
Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> sion:
I felt like it was the best thing to do.
If it takes 3 seconds to get from the first velocity to the second, then what is your best guess about how far it traveled during that time?
answer/question/discussion: ->->->->->->->->->->->-> sion:
Approximately 21 cm as 7 cm/s * 3 s = 21 cm
At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> sion:
change in velocity with respect to time would be acceleration. (10 cm/s - 4 cm/s)/3 s = 2 cm/s/s
