Some of them use. The most modern instruments, don't.
No. Mass is a characteristic that exerts a force of gravity on another mass. The measure of force is the Newton. The Newton uses mass as part of the factors that go into the calculation.
The force of gravity on an object is called its weight.Note that mass is what CAUSES this force of gravity.
NO, weight is a measure of the force of gravity acting on an object. Weight=mass x gravity
No, mass does not vary according to the force of gravity. Mass is a measure of how much matter an object has. Weight, however, is a measure of the force of gravity acting on an object; as such, weight varies according to gravitational field strength.
Yes it is.
A spring balance using a known mass will enable you to measure the force due to gravity [or acceleration].
No. Mass, as a quantity, is independent of gravity.
No. Mass (e.g. grams) is a measure of matter, and is independent of gravity. Weight (e.g. pounds) is a measure of force and is directly related to gravity.
Sagging is one measure of the effect gravity has upon a mass. This can be observed visually, as gravity is constantly pulling everything, including us, down.
Weight is a measure of the action of gravity on a mass.
Gravity.

No, it is a measure of weight, there is a difference (Mass is mass, weight is the force exerted by your mass being pulled down by gravity)
Mass is the amount of matter. Weight had to do with gravity. Weitht is the force of gravity on mass. Some times we use gravity to measure mass such as a spring scale. That does not mean that gravity and mass are the same thing.
A scale or a balance
There are many instruments for mas. Some of the instruments are volume, mass, weight, liter, gram, gravity and meter.
