... g (Spring Stiffness is also measured by the gradient of the graph) Where : T = Periodic Time (s) K = Spring stiffness G = Acceleration due to gravity (m/s) This means that K is the spring stiffness (or spring constant), F is the weight or force applied to the spring and X is the extension of the spring after the force has been applied. Graphically: B Extension (x) The4Horsemen Coursework.Info A Load (F) This is the graph that I expect to find from my results as it means that the extension of the spring will increase proportionally to the force that is applied to it. The graph should also curve at the top as this will be the elastic limit and will be unable to return to its original position and shape. The definition of Hookes law is as follows: An object obeys Hookes Law if the extension produced in it ...
