Hooke's law models the properties of springs for small changes in length

Hooke's experiment, shown in his own work 'de Potetia Restitutiva'

It is a law of mechanics and physics discovered by Robert Hooke.

This theory of elasticity says the extension of a spring is proportional to the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit. Materials for which Hooke's law is useful are known as linear-elastic or "Hookean" materials. view more...
