Experimental Data Mass (g) Degrees (°) Uncertainty of force (mass in g) Uncertainty of force (angle in °) Weight 1 166.0 +/- 0.1 -90.0 +/- 0.5 .1 0.5° Weight 2 166.1 +/- 0.1 30.0 +/- 0.5 .1 0.5 Weight 3 165.8 +/- 8.0 150.0 +/- 2.0 8.0 2.0 Sample Calculation (Force 3): This chart shows the three different masses and the angles at which the forces were applied to the ring. The masses should have been arbitrary however, we used angles of 120 degrees and that is why the masses are all very close to each other. Thus, the forces are all about the same. Direction of Applied Force: Angles (degrees) : -90.0 30.0 150.0 Angle θ (rads): -1.5708 0.5236 2.6180 u θ (degrees): 0.5 0.5 2.0 u θ (radians) : 0.0087 0.0087 0.0349 u sinθ (radians) : 0.000 0.008 0.017 u cosθ (radians) : 0.009 0.004 -0.030 Sample Calculation (Force 3): Using the angle measurements, we calculated the uncertainty of each of the angles in order to account for any miscellaneous errors present in the experiment. The chart shows the different
