Hooke's Law 0.0 / 5 ? FunFunFunNone Created by: HemdevCreated on: 17-02-16 17:06 What is the Hooke's Law? When an elastic object is stretched, the increased length is called its extension. 1 of 8 What is the relationship between the extension and the force? The extension of an elastic object is directly proportional to the force applied to it 2 of 8 What is the equation for Hooke's Law? Force = Spring constant × Extensions (F = k × e) 3 of 8 What is F measured in? The force in newtons, N 4 of 8 What is k measured in? The 'spring constant' in newtons per metre, N/m 5 of 8 What is e measured in? The extension in metres, m 6 of 8 Does the equation work? This equation works as long as the elastic limit (the limit of proportionality) is not exceeded 7 of 8 What happens to the elastic limit when exceeded? If a spring is stretched too much, it will not return to its original length when the load is removed. 8 of 8
