What would happen if normal force didnt exist?

Click For Summary
SUMMARY

The discussion centers on the implications of the absence of normal force in physics. Without normal force, objects would fall through surfaces, leading to a scenario where all matter would converge towards the Earth's center, potentially transforming gravity wells into black holes. The normal force, which arises from electrostatic repulsion between electrons, is crucial for maintaining stability in physical structures. The conversation also touches on the relationship between gravitational force and mass, suggesting that without normal force, the universe could ultimately collapse into a singularity.

PREREQUISITES
  • Understanding of basic physics concepts, particularly forces.
  • Familiarity with electrostatic force and its role in matter stability.
  • Knowledge of gravitational force and its relationship with mass.
  • Concept of black holes and gravitational wells.
NEXT STEPS
  • Research the role of normal force in classical mechanics.
  • Explore the principles of electrostatics and its effects on matter.
  • Study gravitational force and its implications in astrophysics.
  • Investigate the formation and characteristics of black holes.
USEFUL FOR

Students of physics, educators, and anyone interested in understanding fundamental forces and their implications 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
