extension of an elastic object, such as a spring, is directly proportional to the force applied, provided that the limit of proportionality is not exceeded. = spring constant × extension [ F = k e ] F, in newtons, N spring constant, k, in newtons per metre, N/m extension, e, in metres, m A force that stretches (or compresses) a spring does work, and elastic potential energy is stored in the spring. Provided the spring does not go past the limit of proportionality the work done on the spring and the elastic potential energy stored are equal.
