Generally, small scales that measure newtons will have a less firm spring (one with a smaller spring constant) than larger ones that measure tens, hundreds or thousands of newtons or even more depending on the scale of newtons used. When a specimen is placed on the pan the spring stretches along a calibrated scale and a pointer indicates the weight. The Newton spring balance uses a law known as Hooke’s Law to relate the spring extension to the force being measured. In order to infer that the labeled mass values are correct, an object must be hung from the spring balance at rest in an inertial reference frame, interacting with no other objects but the scale itself. He showed that when a spring is fixed at one end and a force is applied to the other, the extension of the spring is proportional to the applied force, provided the force is not large enough to stretch the spring permanently. The larger ones measure tens, hundreds, or even thousands of newtons. Spring balances come in different sizes.
