Aim My aim is to investigate Hooke's law, using masses and springs. Background knowledge When weights are attached to one end of a spring it stretches. Hooke's law states that the extension depends directly on the load, that is: Extension (E) is proportional to the load (M) added. So if this is true doubling the load should double the extension. I know the limit of proportionality is when the spring becomes less stiff and the same force causes a greater stretch than below the limit of proportionality. If you carry on exerting a force on the spring then it looses its elasticity and will not return to its original shape. Prediction As the extension is proportional to the force (load) I think the spring will obey Hooke's law until the limit of proportionality. Plan I think the best way to display my results are in a graph because then you can see exactly how the...
