Data and Calculations: Data Case 1 Case 2 ( θ degrees) 52.84 52.84 L (m) 0.57 0.57 L1 (m) 0.32 0.37 L2 (m) 0.51 0.51 L3 (m) 0.47 0.47 W1 (kg) 0.15 0.15 W2 (kg) 0.15 0.15 Wrod (kg) 0.13367 0.13367 W (calculated) 0.434 0.454 W (experimental) 0.41 0.45 Discussion: There were several opportunities for error to occur. The biggest reason for error is human error. When the objects were being massed, it may have been misread or the scale may have not been zeroed. The lengths may have been measured incorrectly causing there to be a slight error. Conclusion: However in this lab our error was very minimal. In the first case our percent error was 5.53% and our second case had only .88%. If we had to do this experiment once more, we would make sure to zero the scale and make sure that the measurements are accurate. However, my group is extremely pleased with the results, which were extremely close to perfect....
