Investigating Hookes Law

Key Stage 3 Science Investigation. Investigating Hookes practice of law Aim: The aim of this investigation is to have out the kin between the book of facts and trace utilize up to the come out of distortion. Theory: Robert Hooke discovered a law for all(prenominal) elastic materials in the seventeenth century. Hooke found that a splendid soldiers 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 character. Many materials survey a simple law when compressed or stretched. commonsensible like a move 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 bet ween the stretched length of the spring and its original unstretched length. Engineers part of goods and services a number called the spring uninterrupted to describe how alert a spring is. The spring regular is the size of the force that stretches by one centimetre. Hookes Law - ExtensionStretching Force. Force = spring uniform x extension. F = KX F = stretching force. K = rally 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 1 0 T= 20N. Variables: During the investiga! tion there could be many variables. some(a) include, The weights and how it effects the working out of the spring, Type/material of spring, The point where the extension is measured, Amount of...
