PURPOSE: The purpose of this lab was to find that gravity of Earth is indeed 9.8 m/s/s (the theory placed by Galileo). THEORY: The theory, according to Galileo, is that two objects have the same acceleration if dropped from the same height will land at the same time at the speed of 9.8 m/s/s as long as there is no air resistance. To have an understanding Galileo’s theory of acceleration, certain terms …showed first 75 words of 1174 total…

When measuring the intervals, the dots could not be lined up exactly and the second dot could land in-between the centimeter lines. Another human error is the height at which the object was dropped. One of the objects could have been dropped a little higher or a little lower that the other which will make the acceleration inaccurate.
