What would happen if normal force didnt exist?

Click For Summary

Discussion Overview

The discussion revolves around the hypothetical scenario of the absence of the normal force, exploring its implications on physical interactions and the existence of life. Participants consider theoretical outcomes and the nature of forces involved.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that without the normal force, objects would fall through surfaces indefinitely until reaching the center of the Earth, leading to a scenario where gravity wells could become black holes.
  • Others express difficulty in imagining life without the normal force, indicating its significant impact on existence.
  • One participant notes that the normal force is a result of electrostatic repulsion between electrons, arguing that it is not a fundamental force but a consequence of other forces.
  • Another viewpoint posits that the gravitational force would increase due to accumulating mass, leading to a scenario reminiscent of a reverse Big Bang, culminating in a singular mass at the universe's center.
  • A participant agrees with the previous point but speculates on a scenario where only gravitational force exists without electrostatic force.

Areas of Agreement / Disagreement

The discussion contains multiple competing views regarding the implications of the absence of the normal force, and no consensus is reached on the outcomes or the nature of forces involved.

Contextual Notes

Participants express various assumptions about the nature of forces and their interdependencies, but these assumptions remain unresolved and are not universally accepted.

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
