Answer 2

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 .
