What is the relationship between gravity porosity and energy?

Answer 1

gravity is one of the 4 forces of nature: here are the 4 forces of nature:

1. strong
2. weak
3. electromagnetic
4. gravity

in Newtonian mechanics: gravity is more real.. than in Einstein world - where its a space-time-warp and has something to do with topology - and rubber-sheet-geometry

in the real world -> gravity has a value of 9.8 m/second square.. on the moon - the value of gravity = 1/6th of what it is on earth -> that's why people almost fly when on moon..as the force holding their feet on ground is 1/6th less than that on God's earth.

porosity = pertains to a subjective measure or more technically, a relative measure of pores on the surface or the lattice ->

it has nothing to do with gravity.. gravity - in a given reference frame { lets stick to netwonian earth} -> = constant - regardless of the properties of the earthly object.

Engery is very subjective -> but i guess - for most practical purposes, we are dealing with 2 of the most prevalent forms: [ non-chemical}:

[1] kinetic energy

[2] Potential Energy

Kinetic energy is a measure of momentum /speed. velocity -> etc and yes. visceraly one could think of a missile - has more kinetic energy than a stone hurled by a shop keeper in Israel - > kinetic enegry = F ( mass of the object, velocity of the object}

kINETIC ENEGRY = 1/2 m x {VELOCITY) 2

i.e. half times.. the mass times the square of the velocity { mass and velocity of the object who's kinetic energy you want to measure}

th other form of enegry is potential energy -> think of it as "trapped energy - waiting to exhale" -> trapped because its not moving and you cant see - its latent//

imagine the impact of a sumo fighter falling on you - versus the impact of a think-waif-model -> size 4 or size 6 frame - faling on you -> can you feel the potential impact

well, that's luckily just a potential - not a sumo hurled toward you..

Obviously sumo weighs more.. has more MASS ->

and well, as you can guess the gracity of the impact of a sumo falling on you would be - well, felt - and the potential will be realized - as in it would become real - not hypotehical/imaginary

and you can guess -> poetntial enegery hence = function of { mass, gravity and well one more thing}

here is the thing:

imagine -> two cases :

case a : a sumo falling on you from the first floor

case b - a sumo falling on you from the 9th floor?

which case would you - potentailly - avoid? -> let me guess -> the one that has minimum impact ? or enegry ? right?

so., did you say a ? ok/ then

that thing is called : height from the datum : ie. height of the object ( in this case the sumo fighter} from where you are :

so potential energy = f( mass, gravity, height from the reference frame}

= m.g.h { mass multiplied by gravity multiplied by height}

so, to answer your question:

1. gravity has no relationship with porosity
2. gravity is directly proportional to the potential energy*

* if the value of gravity = zero -> then there is no potential energy - can you see why?

1. because gravity = a force that pulls ->
2. if there is no force that pulls objects toward each other.. then which potential are we talking of?
3. In short it wont exist ? the potential ie.. would have a value of zero..

PS: You can see it in your life too..

Answer 2

Porosity refers to the amount of 'empty' space inside of an object. Permeability refers to how well water may flow through material.
