Recently in my physics class we conducted a lab where we had to calculate the k value of a rubber band and spring. In the lab we are supposed to discover that the rubber band does not obey Hooke's Law as nicely as the spring, and that the k value of the spring remains constant with more applied force while the k value of the rubber band changes as more force is applied. The motion of the weight attached to the elastic object demonstrates simple harmonic motion and I observed that the spring caused more uniform motion while the rubber band caused (pretty extreme) dampening. This lab made me wonder: Why do springs like to conform to Hooke's Law more than a segment of rubber band? Beyond material science, does the circular nature of the spring vs the linear nature of the rubber band effect how precise the movement of the object is over time?
