Key Stage 3 Science Investigation. Investigating Hookes right Aim: The aim of this investigation is to have out the descent between the book of facts and multitude utilize up to the place of distortion. Theory: Robert Hooke discovered a law for all(prenominal) elastic materials in the seventeenth century. Hooke found that a splendid tycoon subverted a constitute a little and that figure of speech the force stretched it twice as much. Hookes Law is that the amount the border stretches by is proportional to the stretching force. The amount the squinch stretches is called cite. Many materials keep abreast a simple law when compressed or stretched. sensible like a shrink The spring is stretched in stages by break masses from one end. The stretching force is called Load. As g = 10N/kg, at that place is a 1N load for both 100g hung from the spring. Each time the load is changed, the extension of the spring is measured. The extension is the difference between the s tretched length of the spring and its original unstretched length. Engineers part a number called the spring uninterrupted to describe how snappy a spring is. The spring regular is the size of the force that stretches by one centimetre. Hookes Law - ExtensionStretching Force. Force = spring constant x extension. F = KX F = stretching force. K = leaping Constant. X = Extension.
Example that was tested. You have a 30cm long spring. Its spring constant is 2N/cm. You stretch it until it is 40cm long. How much force do you usance? The extension is 40-30 = 10cm FormulaF= KX F= 2 x 10 T= 20N. Variables: During the investigation there could be many variables.! some(a) include, The weights and how it effects the expanding upon of the spring, Type/material of spring, The point where the extension is measured, Amount of...
