Mass vs Mass as a Force (Weight)

[hutchphd]

You can calibrate the balance so that it measures on a scale proportionally directly to the mass, and it will only be useful in that place, if you move it from latitude, height, it will no longer have that proportionality,

Can we at least keep the physics right? A balance will balance on mars. This differs from a scale which contains a spring. This is the third time I've said this in this thread. Can somebody decapitate this thread?? Please?

Ok, see if we can achieve the same balance on Mars as on Earth ...
, could you tell me

• the air pressure there,
• the acceleration of gravity,
• the radius of the planet,
• the rotation period,
• and the latitude to which you will compare the measurements?

When you define all that, the only thing you can calculate is the apparent weight,
The mass to be measured will remain the same.
The weights only depend on the mass of the planet Mars, the mass of the object, and its relative distance between its centers of mass. , calibrating a balance to measure on a certain scale is a matter of engineering, not physics. .
As other times has happened, can you tell me which part of physics you think I have been overlooked, I do not redefine physics, I do not even try to do so, I think I am not wrong in this case either
The same spring on Mars, comparing the same mass as on Earth, will give different elongation since there is a different apparent weight. What is not understood, what physics have I changed?

A spring is a scale, not a balance. Indeed, a balance measures mass (in vacuum), not weight.

Since it is over 200 posts at this point, I agree that it has outlived its usefulness. Recent posts have been heading in a bad direction.
