Objective : The objective of this experiment was to determine the acceleration due to gravity (g) of a free- falling body under gravitational attraction from the measured rate at which velocity changes with time. Procedure : The falling object, a 200 g weight, was attached to a 60 cm long piece of paper tape. As the weight fel l, the tape was drawn through a timer made up of a small “hammer” which vibrated at a 40 Hz frequency. The hammer left visible incremental marks at 1/40 sec. intervals resulting in a series of in-line dots on the tape representing the position of the weight as a function of time during the fall. These dots were labelled 0, 1, 2, 3… to the end of the tape , with 0 being the origin of both distance and time (? = 0, ? = 0) . From these marks, the distance travelled (? 1 , ? 2 , ? 3 … ???) was measured and labelled as (∆ ? 1 , ∆ ? 2 , ∆ ? 3 … ???) , and the average velocity during each time interval was calculated (? = ∆? ∆? = 40∆?) . All the results were tabulated in Table 1. Data : (original attached) ? = dot number ?
