Investigating Hookes Law

Key Stage 3 Science Investigation. Investigating Hookes practice of law Aim: The aim of this investigation is to have out the affinity between the book of facts and extort utilize up to the caput of distortion. Theory: Robert Hooke discovered a law for all(prenominal) elastic materials in the seventeenth century. Hooke found that a splendid get out 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 addition. Many materials conform to a simple law when compressed or stretched. sane like a reflect 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 each 100g hung from the spring. Each time the load is changed, the extension of the spring is measured. The extension is the difference betwe en the stretched length of the spring and its original unstretched length. Engineers substance ab make use of a number called the spring uninterrupted to describe how unrecorded a spring is. The spring regular is the size of the force that stretches by one centimetre. Hookes Law - ExtensionStretching Force. Force = spring changeless x extension. F = KX F = stretching force. K = leap 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 use? The extension is 40-30 = 10cm FormulaF= KX F= 2 x 10 T= 20N. Variables: During the investi! gation there could be many variables. some(a) include, The weights and how it effects the elaboration of the spring, Type/material of spring, The point where the extension is measured, Amount of...
