Answer 2

Answer:

Friction occur when two surfaces are in constant because everything present in our surrounding have microscopic or visible irregularities.The irregularities of when two surfaces attach themselves then they get interlock with each other.This cause an object stops or produce friction.For example-if the tip of pen do not have any irregularity,then we will not be able to write.
