# Why Can You Not Measure Mass Using a Spring Scale?

August 25, 2022

Answer 1: A balance measures mass by comparing the unknown to a standard mass… like a 1 kg gold standard… on the other hand a spring balance DEPENDS on the local value of G< /b> . A spring balance on EARTH IS CALIBRATED to give the same as the balance on EARTH…

## Can a spring scale measure mass?

Spring scales provide a simple and inexpensive method of mass measurement. The mass is suspended from the end of a spring and the deflection of the spring due to the downward weight on the mass is measured against a balance.

## Why does a spring balance measure weight and not mass?

The spring balance is used to measure the weight of the body while the beam balance is used to measure the mass of the body. Because the mass of the body remains the same on both the earth and the moon, but the acceleration due to gravity is different.

## Why does a spring scale measure mass?

A spring scale measures the weight of an object by opposing gravity with the force of an extended spring.

## What can we measure with a spring scale?

A balanced spring scale can measure weight. Weight is the gravitational force acting on an object. Weight is proportional to mass. Weight depends on measurement location.

## Can gravitational force be measured on a spring scale?

The spring scale is set for a gravitational acceleration of g = 9.8 ms^-2, so when the spring scale reads 1 g, it has actually calculated the force in N and divided it by g to get m. So the spring balance is calibrated for the surface of the earth (sea level), where g is 9.8 ms^-2.

## Why can’t we use a beam balance to measure the weight of a body?

A beam scale does not measure mass; it measures the weight. The pull of gravity between the earth and an object depends on the mass of the object.

## Why mass is measured by physical balance?

The body scale is a weight measuring device that reacts very sensitively to environmental influences. For this reason, the entire structure of the physical scale is placed in a protective glass so that the entire process of measuring the weight is carried out in a vacuum (i.e. without air, wind, sound, etc.).

## How can you measure mass?

The basic SI unit for mass is the kilogram (kg), but smaller masses can be measured in grams (g). To measure mass, you would use a scale. In the laboratory, mass can be measured using a three-beam balance or an electronic balance, but the old-fashioned balance pictured below may give you a better idea of ​​what mass is.

## Does a spring scale measure in Newtons?

A spring scale measures the weight or force when an object is hung from its hook. To measure loose material like sand, put it in a plastic bag and hang the bag on the hook. This has a dual scale that displays 0-1000g in 10g increments and 0-10 Newton in 0.1 Newton increments.

## Does a scale measure mass or weight?

Put simply, a scale measures mass while scales measure weight. So if you take a scale and a scale to the moon, the scale will give you the exact mass of, say, a moon rock, while the scale will be affected by gravity. A scale determines mass by balancing an unknown mass against a known mass.

## Are spring scales accurate?

Spring scales are manufactured, adjusted and assembled with the utmost accuracy and precision.

## What will a spring scale read for the weight?

The upward force exerted by the spring scale is equal to the downward force of gravity. And that will make the upward force equal to weight because it’s equal to gravity. And the weight is mg. The spring scale shows 58 kilograms times 9.8 Newtons per kilogram, which corresponds to 568 Newtons.

## How can we use spring balance to measure the weight of an object?

Body weight is measured with a spring balance. A spring scale has a spring inside. Attached to this spring is a hook that hangs down the body of the spring scale. The object to be weighed is hung on the hook and the weight is displayed on the scale.
