Small error in calculations in first or second line of Earth velocity calcs.........led to high slope of 13.6 m/s/s on your graph of Earth velocity vs. time. In addition, the velocity vs. time for the Moon should be fit with a line (not parabolic). The slope of it should be roughly 1.6 m/s/s.

1.) Below are the links to the data tables with our results:
5.) It takes progressively less and less time as the object accelerates downward to travel 1 meter.
6.) The elapsed times are all the same, even though the distance traveled gets smaller each time. This is also true because the object is accelerating downward and picking up speed.

1.) Below are the links to the data tables with our results:
2.) Earth
a = (vf - vi) / deltaT
a = (-11.11m/s - 0m/s) / 1.08s
a = -10.29 m/s^2
vf^2 = vi^2 + 2 (a) deltaX
0m/s = (-11.11m/s)^2 + 2 (a) (6m)
0 = 123.43 + 12a
a = - 123.43/12
a = -10.29 m/s^2
Moon
a = (vf - vi) / deltaT
a = (-4.35m/s - 0m/s) / 2.69s
a = -1.62 m/s^2
vf^2 = vi^2 + 2 (a) deltaX
0m/s = (-4.35m/s)^2 + 2 (a) (6m)
0 = 18.92 + 12a
a = - 18.92/12
a = -1.58 m/s^2
3.) Earth (both trials, same result)
% Error = | (Known - Experimental) / Known | * 100
% Error = | (-9.28 + 10.29) / -9.28 | * 100
% Error = 10.88%
Moon
% Error = | (Known - Experimental) / Known | * 100
% Error = | (-1.6 + 1.62) / -1.6 | * 100
% Error = 0.22%
% Error = | (Known - Experimental) / Known | * 100
% Error = | (-1.6 + 1.58) / -1.6 | * 100
% Error = 1.25%
