Acceleration Accuracy: Analyses of High-Speed Camera Film

Derwyn Severy, Paul Barbour

Acceleration due to gravity, g, was experimentally determined using the technique of micromotion analysis of high-speed motion-picture film taken of a steel sphere in free fall. Three methods of film analysis were compared with an independently calculated value of g. The analyses used and the error they produced were as follows: graphical, 6%; graphical-analytical, 1%; and analytical, 2%. For all of these experiments, a Bausch & Lomb Contour Measuring Projector was used
