Question

explain the causes of friction​

Answer 1

Explanation:

Friction is a force that resists the relative motion between two objects or materials.

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

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.
