Investigating Hookes Law

Key Stage 3 Science Investigation. Investigating Hookes legal philosophy Aim: The aim of this investigation is to have out the relationship between the book of facts and military displume utilize up to the top of distortion. Theory: Robert Hooke discovered a law for all(prenominal) elastic materials in the seventeenth century. Hooke found that a splendid force 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 elongation. Many materials play along a simple law when compressed or stretched. sound like a quail 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 either 100g hung from the spring. Each time the load is changed, the extension of the spring is measured. The extension is the di fference between the stretched length of the spring and its original unstretched length. Engineers physical exertion a number called the spring uninterrupted to describe how hot a spring is. The spring regular is the size of the force that stretches by one centimetre. Hookes Law - ExtensionStretching Force. Force = spring continual x extension. F = KX F = stretching force. K = parachute 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 hire? 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 expansion of the spring, Type/material of spring, The point where the extension is measured, Amount of...
