Does a spring scale measure weight?

Answer 1

A spring scale is any device that uses the translation of a spring by force due to weight to discover the mass of an object. Let's translate that into easier words. A spring wants to hold its shape. But it is elastic, and if we apply a force to it, it changes shape. The amount of change in its shape will be proportional to the force applied to it. That's Hooke's law of elasticity. Nothing could be simpler. How does that apply? Jump with me and we'll see. By attaching a pointer or dial to a spring in a particular way, we can use the "coefficient of elasticity" of the spring to tell us how much gravity is pulling on something (which is force). We use that something to change the shape of the spring, and by indexing the movement of that spring, that is, setting up a scale or dial, we can use the device (after calibration) to give us a fairly accurate measure of the weight of an object. Most of us are familiar with the spring scale as the so-call "bathroom scale" which is kept secreted away in the water closet. It's a spring scale, and a useful device (though there seem to be more and more electronic interlopers). There are also small versions of the spring scale, too. We find them in home kitchens for weighing food or small objects, as well as in some fishing tackle boxes. Before the electronic age, these little scales were everywhere that there was commerce. Think of all the stuff that gets weighed from meat and produce at the store to the letters and packages at the mailing places. The spring scale used to do all that. And it did it pretty well, too. Links are provided to Wikipedia articles for further reading. A device used to determine the weight of an object (usually fairly light like 10 pounds or less). It uses a spring attached to a hook to work. The object to be weighed is hung from the hook, which compresses the spring. The amount that the spring is compressed is read on a scale that is graduated in pounds.

Answer 2

the spring scale is designed to measure the strength and flexibility of spring it is helpfull in many buisnesses :)

Answer 3

It Measures force.

Which is often 'weight'.

A balance scale technically measures mass.

Answer 5

Yes, a spring scale measures weight. We might also say it measures mass, but a spring scale only works because of gravity, and weight is a function of mass and gravity.
