SUMMARY:

Overall, Graph 1 displays two materials, Y1 and Y2, who coincide with Hooke’s law as they display a positive linear relationship, thus force is proportional to extension. However Graph 2 displays material Z which has surpassed its elastic limit. This is displayed by it polynomial relationship (rather than linear) which suggests that force is no longer proportional to length. The experiment could be improved by completing more trials on the materials and the average being used. This would reduce the number of outliers and provide results which are more trustworthy.
