The tables, Table 1a,1b,1c,1d gave way for constructing a table for change in length as result of applied force for the 5 rubber bands. The tables 2A, 2b, 2c, 2d show that as the forces are increased so does the length of stretch increase. 12N force when applied causes more stretch than the rest of the force, for all the trials. The averages for the change in length caused by the forces were also calculated as shown in Table 3: Averages. These averages in length change were used to build Plotting table, Table 4, as a basis for producing a graph for the relationship. Graph 1 show that all the five rubbers did not exhibit a straight line when the change in length was plotted against force. Graph 2 shows that the relationship between average change in lengths and force does not produce a straight line. This is indicative of presence of outliers in the graph as shown by the dark straight line.
The results indicate that despite increased changed in length as force is increased, rubber does not fully respect Hooke’s Law. The presence of outliers in graph indicates that rubber band does not respect the concept of Hooke’s law, “a graph of force against extension produces a straight line that passes through the origin” (Wilson & Hall, 2009). The inconsistency witnessed results from the nature of rubber’s elasticity, which makes it stress dependent and easily affected by temperature. Intuitively, any slight change in temperature might have interfered with the measurement. This implies that rubber band does not follow Hooke’s law because of the inconsistency in change in
