Document Summary

V1-1 m (g) xm (cm) x = x0-xm (cm) Mass vs. displacemnt y = 8. 0056x + 0. 618. Uncertainty of spring constant: = =(cid:4672)(cid:882). (cid:882)(cid:890)(cid:886) (cid:3030)(cid:4673)(cid:4672)(cid:891)(cid:890)(cid:882)(cid:3030)(cid:3118)(cid:4673)=(cid:889). (cid:887)(cid:888) /(cid:2870) Period^2 vs. total mass y = 0. 0051x - 0. 0148. Spring constant: =(cid:2872)(cid:3118) = (cid:2868). (cid:2868)(cid:2868)(cid:2873)(cid:2869) (cid:3118)/=(cid:889)(cid:889)(cid:886)(cid:882) /(cid:2870) (cid:2872)(cid:3118) The spring constant found in v1-1 is larger than that found in v1-2. If you were to include the uncertainty there are points the two match up. Just considering the spring constant though the value using the method in v1-1 and v1-2 do not yield the same value for k. The introduction to the lab determined that typically varies from 1/3 to 4/(cid:2870). My value, -1. 001, is not within this range. Period^2 vs. length y = 0. 0385x + 0. 125. Uncertainty of y-intercept: (cid:3029)=(cid:882). (cid:882)(cid:888)(cid:887)(cid:889) (cid:2868). (cid:2868)(cid:2871)(cid:2876)(cid:2873) (cid:3118)/(cid:3030)=(cid:883)(cid:882)(cid:884)(cid:887). (cid:1855)/(cid:2870) (cid:2872)(cid:3118) My value of g g does not fall in range of the accepted value of g (980 cm/s2).
