I am asked to determine the force of gravity(9.8 m/s^2) through an experiment which I will conduct. My recourses are very limited and so cameras and accelerometers are out of the question. I have come up with a basic experiment which might work, but I would like reassurance from the forum. Experiment: Using a ticker timer, attach one end of the paper to an object with the dimensions of an eraser(to prevent bouncing, rolling). The object will remain at the very edge of a table top until dropped. Once dropped, the ticker timer strip of paper should contain sufficient data to derive the variable of time; the displacement can be easily obtained from the height of the table. Now that I have known values for t, Δd and Vi(0), can't I substitute them into the linear motion equation a=(2Δd)/Δt^2) to find the acceleration due to gravity? Will it work? What do you suggest I do to get closer to 9.8 m/s^2?
