Why are different tools used ro measure mass and weight?

Answer 1

Mass balances for mass, Newton meters for weight (as weight is a force) are for everyday measurements and basic laboratory experiments as they provide sufficient accuracy and are less technical . For smaller masses mass spectroscopy is used to measure microscopic particles (though this is given in mass/charge ratio) as it is difficult to move a single atom. In space, where there is no gravity and in fact most devices only measure weight and convert this into mass by W= mg; mass is calculated using the spring oscillation formula which means time of oscillation squared is directly proportional to mass. Also mass and weight are not the same thing as one is a force and one is a measure of how much acceleration a force produces.

Answer 2

Mass is a fundamental property of matter and is measured in kilograms using tools like balances and scales. Weight, on the other hand, is the force of gravity acting on an object's mass and is measured in newtons using tools like spring scales. The distinction is important as an object's mass remains constant regardless of its location, while its weight can vary depending on the strength of gravity.
