HEY WELCOME TO MY PERFECT ANSWER-:)
⭕FRICTION⭕
NO,
Friction is directly proportional to the coefficient of serface(u)
Coefficient of Serface➠The Property of surface of roughness and smoothness
➤If the surface has greater roughness then the Friction will act more.
For Example⇶
Tyre of Vechiles are made to be more roughness so that no slide occur.
Conclusion➲
For greater Friction surface should be more roughed which helped in different uses.
