Atmospheric Pressure: Why Don't We Feel It?

Click For Summary

Discussion Overview

The discussion revolves around the question of why humans do not feel atmospheric pressure despite its magnitude. Participants explore various aspects of this phenomenon, including physiological responses and the nature of pressure in different contexts.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that we do not feel atmospheric pressure because our bodies exert an equal pressure in response.
  • Another participant argues that we experience atmospheric pressure in all directions, resulting in a net force of zero when in a normal position.
  • A different viewpoint introduces the idea that the chest does not collapse due to being filled with air at atmospheric pressure, and that other body parts remain intact because water is largely incompressible.

Areas of Agreement / Disagreement

Participants express differing views on the reasons for not feeling atmospheric pressure, indicating that the discussion remains unresolved with multiple competing explanations presented.

Contextual Notes

Some claims depend on specific assumptions about body mechanics and the nature of pressure, which are not fully explored or defined in the discussion.

why don't we feel the atmospheric pressure although it is large ??
 
Physics news on Phys.org
We don't feel it because our bodies are pressing back with the same pressure
 
we feel the atmospheric pressure in all directions and the net resultant force will be zero
EXAMPLE :if we are in the normal position we feel the pressure in all directions and the net is zero
if we are infront of the moving train outer atmospheric pressure is more than the pressure between train and us
 
These are not quite right. There are two reasons/cases: first, your chest doesn't collapse because it is filled with atmospheric pressure air. Other parts don't collapse because water is largely incompressible.
