Question

Q. What is the cause of friction between two surfaces?


please give me a correct answer.​

Answer 1

Answer:

Friction is caused due to the irregularities on the two surfaces in contact. Even the smoothest surfaces have minute irregularities in them and these irregularities of the two surfaces interlock into each other and create friction. Larger the irregularities more is the friction.

Answer 2

Answer:

====>Friction is the force that resists he relative motion between two objects of material.

Explanation:

===>The cause of this resistive force are molecular adhesion, surface roughness and deformations.
