Causes of Friction:-
- Adhesion is a molecular force that arises when two materials are brought close to each other.
- Surface roughness is a factor in friction when the materials are rough enough to cause serious abrasion.
- When one or more of the materials are relatively soft, much of the resistance to movement is caused by deformations or a plowing effect.
