A spring balance comprises a spring fixed at one edge with a hook to join an object at the other. They are often used to measure the force exerted on an object. This force is usually measured in newtons, a.k.a. the weight of an object, and achieved using Hooke's law. It is also called Newtonmeters for this reason.
