What would happen if normal force didnt exist?

AI Thread Summary
Without the normal force, objects would fall through surfaces, leading to a scenario where everything collapses toward the Earth's center. This would result in gravity wells potentially becoming black holes, as the ground itself would also succumb to this collapse. The normal force, which arises from electrostatic repulsion between electrons, is crucial for maintaining balance against gravitational pull. If the normal force were absent, the consequences would be catastrophic for the structure of matter and life as we know it. The discussion highlights the interdependence of forces and the critical role the normal force plays in the universe.

The title says it all.
--thank you

Things would fall through your table, through the floor, through the ground till they reached the center of the Earth. Even the ground would fall to the center of the Earth. I guess every gravity well would become a black hole.

Force Normal holds things up. It balances the force of an object pushing down.

But don't worry, it can't happen.
 
Thanks for clearing that up. Its hard to imagine how any life could possibly exist without it. I had know idea that it had such a great impact.
 
The normal force between a table and a book resting on it arises from the electrostatic repulsions between the electrons in the book and the electrons in the table.
So, the Normal force is not a fundamental force. It is merely a consequence of the electrostatic force.
 
i feel gravitational force of a body would keep increasing due to increasing mass and one more thing that would happen is theb reverse of the BigBang that is eventually we will end up with just a singular large mass at the center of the universe.
 
i believe sidharth is right. but just imagine electrostatic force didnt exist but gravitational force existed
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
