Since glaciers have mass, what specifically is mass? Can we define it . We can define mass.
On Earth, a 1 kilogram weight has 9.81 newtons of force. This is not mass. Also, something weighing 1 kilogram on Earth is not mass. Mass is what a 1 kilogram weight weighs at sea level in the Earth's gravitational field.
If it were at an elevation of 1,000 feet or 300 meters (2 different things), it's weight would be less. Away from the Earth's gravitational field, a 1 kilogram weight would have mass but no weight.
This makes it's mass and weight relative to the Earth. Why does this matter?
f = ma and ma = m(d/t). Force is mass times acceleration. And acceleration is distance divided by time. Just some basic stuff here.
And with glaciers, they have mass but no acceleration or velocity. This means they have no force or momentum. This is where with plate tectonics we need to consider weight (not mass, a mass occupies space or a given volume considered as space) and leverage.
This gets into other things as well if we stay on topic. And for now, this debate is about the difference between, weight, mass and force. This in my opinion will help people to understand the difference between tectonic plate depression and tectonic plate rebound.

p.s., am sorry guys, am just bored silly off of my a$$. Then again, we might live on a planet that's actually "pretty cool".

Guys, this is an easy one. You can understand the difference between weight and mass. Mass has no weight.

There was this guy name Albert who defined mass several decades ago. He defined it as energy divided by the speed of light squared ... and that causes curvature in space-time.

I don't see any problem with his definition. It seems to be externally consistent and has fared pretty well in standing up to the scientific method. What do you think?

You got it wrong. He defined energy as mass divided by the speed of light squared. He was referencing light while I was discussing matter. 2 different things.

Au contraire mon frere, in defining the Energy-Mass relationship, he was defining mass as a form of energy ... and specifying exactly how much. This is why you can enter your mass value as an independent variable and calculate the amount of energy it represents as a dependent variable.

Try it, it works.

Yes, the reverse works as well. Photons have mass although they are not matter.

Planck*LightSpeed/Wavelength = Energy = mass*LightSpeed^2

Ergo

Planck*LightSpeed/Wavelength = mass*LightSpeed^2
Planck/Wavelength = mass*LightSpeed
Planck/[Wavelength*LightSpeed] = mass

where

Planck('s Constant) = 6.63 × 10-34 Joules / second
LightSpeed = 299,792,458 meters / second

Pop in your photon's wavelength as an independent variable and calculate its mass as a dependent variable.

Don't you know Anglais garcon?

It's hc/lamda = E = m(c*c)

It's kind of like satellites basically have no weight. Why they stay up so long.
With photons, they used to say they had no mass because they don't have a "rest" position. They've changed their thinking on that.

There is no such thing as a 'rest position'. Zero is decided by you. Speed is relative.
