Experiment to Determine the Magnitude of Acceleration Due to Gravity, g In this lab, we will be conducting an experiment to determine the magnitude of acceleration due to gravity, g. The setup shown includes a device that can vary the angular speed, Wo, given to a solid sphere with mass M and radius R. The solid sphere will roll to the right on the top of a horizontal table without slipping, with an angular speed of g. The table has a length Z and is a height h above the ground. After rolling across the table, the sphere will then fall off the table. To find g, the students will plot their data on a graph. The students have access to equipment commonly found in a high school physics laboratory, but they must use the setup shown. The equation for the moment of inertia, I, is given by I = MR^2. (c) Which quantities (raw data or calculated from the data) would be graphed on the vertical and horizontal axes to produce a graph that could be used to determine the magnitude of acceleration due to gravity, g? (d) Describe which information from the graph described in part (c) would be used and how it would be used to determine the magnitude of acceleration due to gravity, g. (e) Another group of students performs the same experiment, but they use hollow spheres of the same diameter and mass as the solid spheres used by the other group. The new group of students follows the same procedure and analysis as described in part (b) through part (d) without adjusting for the difference in the spheres. Will the calculated magnitude of g determined using the hollow sphere be greater than, less than, or equal to the magnitude of g obtained in the experiment with the solid sphere?
