Why is it that it's the gravitational force that keeps me on the ground?

AI Thread Summary
Gravitational force is the primary reason objects remain grounded, despite the electrical force being significantly stronger at the atomic level. While electrical forces are balanced on Earth, resulting in no net force due to the neutral charge of atoms, gravity acts on mass. Humans, having substantial mass but negligible charge, experience gravitational attraction towards the Earth. The electromagnetic force prevents objects from passing through each other, but gravity is the dominant force keeping them anchored. Understanding these forces clarifies why gravity, rather than electrical force, is responsible for keeping us on the ground.

Rather than the electrical force?

In general, and by the equation, electrical force is much stronger than the gravitational force!

Electrical force are balanced. In other words, the summation of electrical charges on Earth should be zero, so there is no forces. You are made of atoms, which are have 0 electrical charge, and the Earth is made of atoms too, so no force in between.

Between a pair of charged elementary particles--like an electron or proton--the electrical force is much stronger than the gravitational force. But you are not a charged particle--you have a huge mass (compared to either of those) and essentially zero charge.
 
Well, electromagnetic force keeps you from falling THROUGH the ground but since you have no net charge, there is no basis for a long distance force.

Thread 'Question about pressure of a liquid'

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
