Key Stage 3 Science Investigation. Investigating Hookes Law Aim: The aim of this investigation is to find out the relationship between the extension and force applied up to the point of distortion. Theory: Robert Hooke discovered a law for all elastic materials in the seventeenth century. Hooke found that a small force stretched a spring a little and that double the force stretched it twice as much. Hookes Law is that the amount the spring stretches …showed first 75 words of 949 total…

…showed last 75 words of 949 total…the spring was measured from the same point each time. I think everything went fair. I didn't encounter strange results like, the spring extending by 10mm each time. I have leant not to rush things. I think I should have spaced my investigation out so I wouldn't have to rush. I think if I could do the experiment again I could make it more accurate. I might even have better results or even strange results.
