The Electromagnetic force is the only microscopic force causing friction, but the explanation of that force is not simply based on electrostatics or classical electromagnetic theory.
The forces involved with friction are ultimately the forces between atoms at the interface between two materials.
Atoms may attract, repel and become chemically bonded and those processes must be described using quantum theory.
In some cases, atoms or molecules at the interface are charges or have dipoles or other complex charge distributions which interact with other charges or charge distributions through simple laws of electrostatics.
But, neutral atoms interact even when the isolated atoms have no charge and a simple spherical charge distribution. The interaction between neutral atoms and molecules which are far apart (further apart than a few angstroms) are termed "van der Walls forces" and such forces are weakly attractive. When atoms or molecules are closer, then they may develop a chemical bond. If they do not develop a chemical bond that moving even closer results in a rapidly increasing repulsion when the electron clouds of two atoms begin to overlap. This is a result of an increase in the kinetic energy of electrons and also includes some coulomb (electrostatic) effects.
The forces between atoms at close range (the repulsive forces and the van der Waals forces) are not simply electrostatic in origin. The full explanation resides in the quantum mechanical laws governing the electronic structure of the atoms and molecules.
What else can I help you with?
What is the difference between fundamental and non fundamental force?
Fundamental forces are the four fundamental interactions in nature (gravity, electromagnetism, strong nuclear force, and weak nuclear force) that govern particle interactions at a fundamental level. Non-fundamental forces are derived from these fundamental forces, such as friction or tension, that arise from interactions at a macroscopic level.
When the four fundamental forces which is the weakest?
Gravitational force is the weakest of the four fundamental forces. It is much weaker than the electromagnetic, weak nuclear, and strong nuclear forces.
Which of the four fundamental forces isn the weakest force?
Gravity is the weakest of the four fundamental forces. Its effects are only noticeable when dealing with large masses such as planets and stars.
Who do scientists identify as the four fundamental forces of nature?
The four fundamental forces of nature identified by scientists are gravity, electromagnetism, the weak nuclear force, and the strong nuclear force.
What is the name of all the forces?
I know some of it and they are:- - gravity - compression - tension - friction - torsion - buoyancy - shear
What is the difference between fundamental and non fundamental force?
Fundamental forces are the four fundamental interactions in nature (gravity, electromagnetism, strong nuclear force, and weak nuclear force) that govern particle interactions at a fundamental level. Non-fundamental forces are derived from these fundamental forces, such as friction or tension, that arise from interactions at a macroscopic level.
Does string theory negate the four fundamental forces?
String Theory does not negate the four fundamental forces, it explains them in another way.
What are four forces in static friction?
Four forces in static friction are:- 1. Weight 2. Tension 3. Normal Force 4. Static Friction
When the four fundamental forces which is the weakest?
Gravitational force is the weakest of the four fundamental forces. It is much weaker than the electromagnetic, weak nuclear, and strong nuclear forces.
What are the 4 physical relationship?
Do you mean the four fundamental interactions? These are also known as the four fundamental forces. They are electromagnetism, gravity and the strong and weak nuclear forces.

Which of the four fundamental forces makes paint cling on the wall?
electromagnetic
What is the weakest natural force?
Of the four fundamental forces gravitation is, by far, the weakest.
Which fundamental force is the unification of two forces?
The electroweak force is the unification of the electromagnetic force and the weak nuclear force, two of the four fundamental forces in nature.
What are the 4 natural forces?
The four fundamental natural forces are gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. These forces govern interactions between particles at the atomic and subatomic levels in the universe.
