Unformatted text preview: Conclusion: Our Torque vs. Angular Acceleration graph shows us that our results were acceptable, and highly preferred. Since our percent uncertainty was less than 5 % we can say that our experiment was with little error. To make this experiment better, we could have ensured that the string didn’t get caught up or that the smart pulley was not getting pushed back by the spinning disk in the first place –which happened for our first few run through trials. Also, measuring the diameters to calculate the moments of inertia for both may not have been completely accurate, as we used a ruler to measure the larger disk and a caliber to measure the diameter of the smaller one. Using two different measurement devices allows for some discrepancy. But overall, since we had an R^2 value of .998/. 995 and our graph demonstrates pretty normal trends for the slope, we can say that our graph provides us enough evidence that our experiment was successful....
