8/31 1120Average velocity = average roc of position of measured object wrt clock time.
Average acceleration = average roc of velocity wrt clock time.
Instantaneous velocity = limiting value of average roc of position with respect to clock time with time intervals containing that instant as the time intervals approach 0.
