Answer:
To discuss the nature of friction, we need to have some common definitions: friction can be defined as the resistance to motion of a mass; frictional force is the force necessary to overcome the resistance to motion; static frictional force is the force necessary to overcome the resistance to motion from rest.
The causes of friction are:
- Molecular Adhesion
- Surface Roughness
- Plowing effect
