Obtaining the Calibration Curve
Click to do
calculations for finding the Acceleration of Gravity.
Acceleration of Gravity is the slope of the best straight line fit =
cm/s/s (or cm/s2)
Percent error (using g = 980 cm/s/s) = %
Since the above calculation for the slope has been done by regression analysis, your value may be
a bit different. However, if there is a difference of more than 10, your line may not be a good
straight line fit. Check that the distances between the line and points above the line are about
the same as the distances between the line and points below the line.
