SUMMARY

When hitting a wall, the pain experienced is due to contact forces, specifically electromagnetic repulsions between the atoms in your hand and those in the wall. The stopping force, known as the normal force, is fundamentally an electromagnetic force resulting from the repulsion of electron shells. This interaction triggers nerve endings to emit electric pulses to the brain, signaling pain. Understanding these forces clarifies the nature of physical impacts and the body's response to them.

PREREQUISITES
  • Basic understanding of contact forces
  • Knowledge of electromagnetic forces
  • Familiarity with atomic structure and electron shells
  • Awareness of human physiology related to pain perception
NEXT STEPS
  • Research the principles of electromagnetic repulsion in atomic interactions
  • Study the mechanics of normal force in physics
  • Explore the role of nerve endings in pain signaling
  • Investigate the relationship between contact forces and physical injuries
USEFUL FOR

This discussion is beneficial for physics students, medical professionals, and anyone interested in the mechanics of pain and physical interactions in the context of human anatomy and physics.

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.
