Sir, what is the origin of friction..Is it roughness or sumthing other ..Plzz explain?
Please find below the solution to the asked query:
Friction is the resistance force acts between the two surfaces in contact.
Friction is the Electromagnetic Force. because, when two surfaces are in contact with each other, then the atoms of each surface makes chemical bonds with the atoms of the other material surface. Therefore, to brake this bonds we have to apply some force. This required force is called the frictional force.
Friction force will be divided into two parts mainly,
- Static Friction,
- Kinetic Friction.
