Description
A spring scale or spring balance or Newton meter is a type of weighing scale. It consists of spring fixed at one end
with a hook to attach an object at the other. It works by Hooke’s Law, which states that the force needed to extend a
spring is proportional to the distance that spring is extended from its rest position. Therefore, the scale markings on
the spring balance are equally spaced. A spring scale cannot measure mass, only weight.
