NettetWithin certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke's law and commonly written: \boxed {F=-kx} F = −kx. Where F F is the force, x x is the length of extension/compression and k k is a constant of proportionality known as ... NettetDefinitions. A linear spring is one with a linear relationship between force and displacement, meaning the force and displacement are directly proportional to each other.
