Physics Coursework Extension of a metal spring investigation Aim: In this experiment I will try to investigate the factories, which affects the extension of a metal spring. Background information I think in this experiment as you increase the force on a metal spring then the metal spring stretches, and as you increase force more and more the metal spring will increase more. And we call this TENSILE STRENGTH. A piece of a metal spring can be compressed by equal and opposite force applied to its ends. When the force are removed, the metal spring will returns to its original shape. I think the following factors affect the extension of a metal spring: * The Length. * The thickness. * The applied force. * The material of the spring. 1. The length will affects the extension of a metal spring this is because the longer the spring will be the greater the extension will be. 2. The thickness I think this...
