Experiment: How does the weight hung on the end of a piece of rubber cord affect the extension of the cord? Aim: The aim of this experiment is to investigate how the weight hanging on the end of an elastic cord affects the extension of the cord being pulled downwards. Prediction I predict that the greater the weight applied to the cord, the further the cord will stretch.I predict this because, according to Hooke's Law, extension is proportional to load and so if load increases so does extension and so stretching distance. I think that the extension will be greatest when more weight has been added onto the end. Method: We will look at the effect of the weight applied, as it is a continuous variation. We will vary this by adding 10g of weight onto the end of the cord each time and measuring the length of the cord using a tape...
