Is a balance used to measure mass or weight?
Technically, a balance compares weight rather than mass, but, in a given gravitational field (such as Earth’s gravity), the weight of an object is proportional to its mass, so the standard masses used with balances are usually labeled in units of mass (e.g. g or kg).
Whats the purpose of a balance scale?
A balance scale is an instrument used to measure the weight of objects by comparing their weights to a set of known weights.
How is balance related to mass and weight?
Balances measure mass by the reducing the difference in “weight” between the known mass and the unknown mass to zero, i.e., “in balance”, therefor balances will give the same results on earth, the moon, mars, etc. Since mass is not gravitationally dependent and weight is, balances are measuring mass.
Why does a spring balance measure weight and not mass?
Does spring balance measure weight or mass? The spring balance opposes the force of gravity with the force of the extended spring and measures the weight of an object. Was this answer helpful?
Why would you use the same balance when measuring mass in the lab?
This mass, accurate to the nearest 0.1 mg, can be stated in your laboratory reports. Use the same balance. It is critical to always use the same balance especially if calculations require more than one mass measurement, as each device might be calibrated slightly differently.
What is balancing the scale?
A balanced scale refers to an ordinal question asked to the respondents of a piece of research. It is mainly used in quantitative market research questionnaires and surveys. A balanced scale question is one which asks individuals to answer a question based on a given scale.
How does a balance measure mass?
Balances Measure Mass A true balance measures mass directly by comparing the unknown mass to a known mass, a process that is not affected by changes in gravity. A balance of this sort will give the same reading irrespective of location because gravity will act on both sides of the balance equally.
What is the difference between a balance and a scale?
The biggest difference to remember is that a balance is used to measure mass whereas a scale is used to measure weight. Originally, balances were equal-arm balances, where a weight was put on one side and a product was put on the other to get a comparison between the two.
Why is spring balance used to measure weight?
Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.
Do spring scales measure weight or mass?
An oscillating spring scale can measure mass. Mass is independent of measuring location. Mass is measured by acceleration. A spring scale in equilibrium can measure weight.
Why is it important to use the same balance?
Why is it important to always use the same balance during the course of an experiment? The different balances could be off and calibrated differently, which could give you inconsistent masses throughout the experiment, which may give you incorrect results in the end.
