Testing Hooke's Law By Daniel Bowman 11CU Introduction Hooke's law is when forces applied to a solid object and it can result in extension or compression. Hooke's law is able to predict how a stretchable object would behave when a force is applied to it. Planning I aim to show how much force strips of black bin liners (polythene) will take before it reaches its elastic limit and obey Hooke's law. I will also investigate if the length of the strips can alter the results, keeping the width the same. The main suitable equipment I will need to use may include the two different types of plastic cut at different lengths and 100g masses to test the extension. I will obviously need other basic apparatus to carry out the investigation. My experiment will last until each strip of plastic splits, so I cannot at this time state how many masses I will require. Polythene The...
