Why Does Friction Exist? Explaining 4 Forces

[Thinker301]

How does friction come about using the four forces?

It comes from the electromagnetic interaction of the atoms of the two surfaces rubbing against each other.

I see, but is it because of deformities at the microscopic level or chemical bonds? Essentially what's I'm between. How does the electric force become friction.

When you have a rough surface, it will have many "mountains" and "valleys". Your hand will also have these. When they rub against each other,the electrons of the atoms of your hand's mountains repell the electrons of your rough surface's mountains. This is the force.

Note: I don't mean actual mountains

Friction exists due to the presence of four fundamental forces: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. Each of these forces plays a role in the creation and effects of friction.

Firstly, gravity is responsible for the weight of objects and their interaction with each other. When two objects come into contact, the gravitational force between them causes them to push against each other, resulting in friction.

Secondly, electromagnetism is the force responsible for the interaction between electrically charged particles. When two surfaces come into contact, the atoms and molecules on their surfaces interact through electromagnetic forces, causing them to stick together and create friction.

Thirdly, the strong nuclear force, which is responsible for holding atomic nuclei together, also plays a role in friction. When two objects come into contact, the strong nuclear force between the atoms in their surfaces causes them to resist being pulled apart, resulting in friction.

Lastly, the weak nuclear force, responsible for radioactive decay, also contributes to friction. When two surfaces are in contact, the atoms in their surfaces may undergo radioactive decay, releasing energy that creates a resistance to motion, resulting in friction.

In summary, friction is a result of the interactions between four fundamental forces: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. Each of these forces contributes to the resistance experienced when two surfaces come into contact, making friction an essential aspect of our physical world.
