In this experiment you will measure the distance of a mass of (small stone, ball, small piece of a thick paper from a box) fallen during recurring time intervals according to a timing device. This data will enable you to calculate the instantaneous velocity at known time intervals. Plotting the velocity vs. the time, then finding the slope will provide an experimental value of g.
