The two forces that compress a spring inside a weighing scale are the force of gravity acting on the person standing on the scale and the reaction force exerted by the spring in the scale to counteract the force of gravity. This compression of the spring is used to measure the weight of the person.
The unit used on spring scales is 'Newtons.'
Robert Hooke (1635-1703). The experiments of Robert Hooke showed that the extension of an elastic spring is proportional to the force that is applied to the spring . The spring scale operates on this principle.
A spring scale is used to measure the force exerted on an object by gravity or by a person pulling on it. It measures this force in units of mass, such as grams or kilograms.
The form of energy involved in weighing fruit on a spring scale is elastic potential energy. When the fruit is placed on the scale, it compresses the spring inside, storing potential energy. This energy is then used to counteract the force of gravity acting on the fruit, allowing the scale to indicate the weight.
A spring scale is used to measure force or mass
Not really...A spring scale is largely inacurate. For Chemical or Scientific purposes, a spring scale is not the answer.
Not to appear somewhat insulting here...But the answer's in the question, weighing things.
A spring scale is used to measure the weight of an object by the stretching of a spring. It is commonly used in schools, laboratories, and households to measure the force exerted by an object due to gravity.
A spring scale
A weighing scale (usually just "scale" in common usage; except in Australian Englre "scales" is more common) is a measuring instrument for measuring the weight or mass of an object. They use one of two techniques. A spring scale measures weight by the distance a spring deflects under its load. A balancecompares the unknown weight to a standard weight using a horizontal lever. Weighing scales are used in many industrial and commercial applications, and products from feathers to loaded tractor-trailers are sold by weight.
Objects can be compared based on their mass using a balance scale, a spring scale, or by measuring their weight using a tool like a digital scale. The units for mass are typically measured in grams or kilograms.
