Discussion Overview

The discussion explores the types of forces involved when a person hits a wall and experiences pain, specifically questioning whether these forces are electrodynamic in nature. The scope includes conceptual understanding of forces, particularly in the context of contact and electromagnetic interactions.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that the force felt upon hitting a wall is a contact force.
  • Another participant claims that nerve endings emit electric pulses to the brain to indicate pain, proposing that the contact force is electrostatic due to electromagnetic repulsions between atoms.
  • A participant questions the nature of electromagnetic forces involved and seeks clarification on how the normal force is classified as an electromagnetic force.
  • It is stated that the normal force, which stops the hand, is an electromagnetic force.
  • Another participant challenges the classification of normal force as electromagnetic and asks for further explanation.
  • One participant asserts that the force arises from the repulsion of electron shells between the hand and the wall.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the forces involved, with some supporting the idea of electromagnetic forces while others question this classification. The discussion remains unresolved regarding the exact nature of the forces at play.

Contextual Notes

Participants have not fully defined terms such as "normal force" or "electromagnetic force," and there are unresolved questions about the mechanisms behind the forces described.

hit a wall,u feel pain,what kind of forces r involved,r they electrodynamic?
 
Physics news on Phys.org
A contact force.
 
your nerve endings emit an electric pulse to the brain indicating pain.

the actual contact between your hand and the wall is electrostatic in nature because the stopping force is due to electromagnetic repulsions between atoms in your hand and those on the wall.
 
how r they electromagnetic,please explain.
 
It is the normal force that is stopping your hand. The normal force is an electromagnetic force.
 
why is normal force an electromagnetic force?
 
What other kind of force would it be?
 
u must be right,but tell me how is it an electromagnetic force?
 
The force is the result of the electron shells repelling each other.
