Converting gravity into pressure inside the very center of a planet

[lexdean]

Homework Statement

We know IO Jupiter's moon creates heat as gravity changes. The volume of atoms must play a role in the amount of gravity some how. So mass, gravity volume and pressure in the very center of a planet must relate to rach other some how.

Relevant Equations

Ms2 = psi = mass

Gravity in the very center of the planet must be zero because all other atoms are pulling evenly around the center.
We have a deap gold mine in South Africa and uranium waste storage Norway.
Has the force of gravity shown change at these depths. Even at the bottom of the Pacific ocean gravity must have been measured. Is Earth's crus
And has this type of study made a relationship as different planets have different desitys.
Even the different types of atoms in a planet must make changes to the results. Our plant's atmosphere is bonbarded with solar rays that a balance between gravity and the strength of solar ray bonbardment must be related unless our atmosphere is still growing that I dealt.

So the question I should first ask is what is known.

Acceleration due to gravity is zero, yes.

Yes, we can measure changes in gravity in depressions in the Earth.

- different planets have different densities
- different types of atoms in a planet

These are all factors that are included in the planet's mass.
The other thing that affects your wight on the surface* is the radius of the planet.

*and, I suppose, whether it has a surface to speak of

About what ? Most of your ramblings seem rhetorical.

Io's heat is a result of lots and lots of external gravity sources.

Yes, your "solar rays" push the Earth into a slightly higher orbit than it would be, without ... say half a kilometre ? Total guess. You want a seriously impressive example, look up how stars work, particularly supernovae.

ps: spellcheck and proofread. And, why is it in the Homework section ?

…

The heat is generated in Io by changing external fields which squeeze it in changing directions.
The excess heat within the Earth (compared to the surface) is mostly a result of two causes:

• Primordial heat from the gravitational energy released as the Earth formed from the solar system’s protoplanetary disc.
• Decay of radioactive elements within the Earth.

As Lord Kelvin showed, if it were not for the latter there'd be little primordial heat left.

For neither body is the heat in any way a result of how the body's gravitational field varies with depth.
