Aim: The aim of this coursework is to prove if Hookes Law's theory of extension is proportional to length is true. Scientific Knowledge: Robert Hooke investigated springs nearly 30 years ago. He found that the extension was proportional to the stretching force so long as the spring was not permanently stretched. This means that doubling the force doubles the extension, trebling the force trebles the extension and so on. Using the sign for proportionality we can say write Hookes Law as: EXTENSION IS PROPORTIONAL TO STRETCHING FORCE. Prediction: I predict that the extension will be proportional to the stretching force so long as the string is not permanently stretched. This means that the results should be near enough consistent while increasing in the extension until I reach the end of the experiment. Safety Precautions: I am going to make my experiment safe by wearing safety goggles, just incase the spring breaks and bounces back to my eye....
