... SCENARIO: Investigate whether elastic bands and springs behave the same way. AIM: When a load(weight) is applied to either an elastic band or a spring, do they return to their original length i.e. is the extension directly proportional to the load. BACK GROUND INFORMATION: The structure of elastic bands and springs are different. By studying a Newton metre, I noticed that the marks between each Newton applied were equidistant. This implies that a spring returns to the original length, therefore the load and length are directly proportional. This is because the structure of a spring is coiled. Therefore the molecules have been twisted and pulled apart, this creates the spring, as the molecules try to pull themselves back together. An elastic band is made of polymers. Hooke's Law states when a material is stretched, the change in length is directly proportional to the stretching force applied. However when an elastic limit is reached the material
