Question

What is friction and it's causes

Answer 1

Answer:

Friction is the resistance that one surface or object encounters when moving over another.

The causes of this resistive force are molecular adhesion, surface roughness, and deformations.

Answer 2

Friction is the resistance to motion of one object moving relative to another .

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 .
