Hooke's Law

Hooke's Law

When an elastic object - such as a spring - is stretched, the increased length is called its extension. The extension of an elastic object is directly proportional to the force applied to it

F= k x e

F is the force in newtons, N

k is the 'spring constant' in newtons per metre, N/m

e is the extension in metres, m

This equation works as long as the elastic limit (the limit of proportionality) is not exceeded. If a…
