Unformatted text preview: REPORT FOR LAB M11: ROTATIONAL DYNAMICS VI-1: In this experiment we studied the effects of rotational dynamics by measuring the effect varied mass has on acceleration over a fixed distance. By measuring the time it takes for the mass to hit the ground from a fixed height h, we can calculate the acceleration of the mass based on the equation 2 2 t h a = . Below are the tables for the results from V-1a and V-1b. M steel = 657.0gm m holder = 5.9 gm h = 90 cm R = 6.32 cm r = 1.23 cm m (gm) m total (gm) t 1 (s) t 2 (s) t 3 (s) t 4 (s) t 5 (s) t 6 (s) t (s) 2 2 t h a = (cm/s/s) 5.9 22.15 22.12 22.24 21.71 22.25 22.17 22.12 0.3679 5 10.9 15.84 15.95 16.18 16.26 16.05 15.85 16.02 0.7014 10 15.9 13.47 13.49 13.40 13.57 13.45 13.50 13.48 0.9906 15 20.9 11.47 11.74 11.46 11.73 11.50 11.65 11.59 1.3400 20 25.9 10.51 10.53 10.46 10.48 10.50 10.52 10.50 1.6326 VI-2: Using Excel I was able to plot a vs. m total using the data from the above table. The points of the graph lie on a straight line with a slope that is represented by the equation exp , 2 D I gr S = where exp , D I is the rotational inertia of the steel disc which I will be able to find as a result of the graph and plot. The graph and table of values given of the steel disc which I will be able to find as a result of the graph and plot....
