Objective: The objective of this experiment was to find the acceleration due to gravity based on the distance of the dots on the free falling mass, and its changes with time. Introduction: Before the 16 th century it was assumed that that an object with less mass would fall slower than an object with a larger mass. Aristotle had published a book called Physics sometime in the mid 300 BCE. It was popular and became a widely accepted book among academic societies. In 1589 Galileo Galilei went to the top of the Leaning Tower of Pisa and dropped to balls of differing masses to show that the time of the descent was unaffected by the mass of object. The experiment was repeated 100 times until, “ an accuracy such that the deviation between two observations never exceeded one-tenth of a pulse beat” was achieved. He then published his book
