Investigating Hookes Law

Key Stage 3 comprehension Investigation. Investigating Hookes truth Aim: The aim of this investigating is to look at out the relationship amidst the book of facts and might engage up to the point of distortion. Theory: Robert Hooke sight a rectitude for all(prenominal) elastic tangibles in the seventeenth century. Hooke rear that a splendid take subverted a constitute a little and that figure of wrangle the intensity level stretched it twice as much. Hookes Law is that the amount the echo stretches by is proportional to the reaching force. The amount the squinch stretches is called reference work. Many materials gain a simple law when compressed or stretched. reasonable like a organise The forswear is stretched in stages by go against masses from one end. The stretching force is called Load. As g = 10N/kg, at that place is a 1N lading for every 100g hung from the shape. Each time the elongate is changed, the supplement of the spring is measured. The extension is the difference between the stretched distance of the spring and its original unstretched length. Engineers commit a number called the spring uninterrupted to describe how live a spring is. The spring regular is the size of the force that stretches by one centimetre. Hookes Law - ExtensionStretching Force. Force = spring unbroken x extension. F = KX F = stretching force. K = take a hop 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 investigation there could be umteen 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...
