A. The quadratic curve fit yields coefficients A, B, and C. What does A represent? Use this
calculate the percent difference for g a second time.
B. Pick two points on your graph of average velocity versus time, one on the line near the
beginning of the data and one on the line near the end of the data. Find the "area" under
this curve (note that this is not really an area). What does what you have found represent
physically?
C. Classify the following as to whether the error each introduces is random or systematic or
possibly both: (a) air friction, (b) measurements of length estimated to fractions of a
millimeter, (c) fluctuations in the spark time intervals, and (f) error in the value of the
frequency of the spark source.
