ppefmh	Ed	Garstin	5/5	The graph represents the results.		When we apply a force to a spring and we measure the extension, we get a straight line graph that passes through zero. This tells us the extension is directly proportional to the force applied. When we apply a force to a spring and we measure the extension, we get a straight line graph that passes through ten. This tells us the extension is directly parallel to the force applied. When we apply a force to a spring and we measure the extension, we get a straight line graph that passes through zero. This tells us the extension is directly inverse to the force applied. When we apply a force to a spring and we measure the extension, we get a straight line graph that passes through ten. This tells us the extension is exponential to the force applied.	35mm 45mm 10mm 55mm	70mm 60mm 80mm 95mm	Exceeding the limit of proportionality, the spring extends more for the force applied. Exceeding the limit of proportionality, the spring extends less for the force applied. Exceeding the limit of proportionality, the spring extends the same for the force applied. Exceeding the limit of proportionality, the spring extends the inverse for the force applied.	142.857 N/m 132.857 N/m 0.14 N/m 0.7 N/m	100%
