Question

force of friction depends on answer is roughness of surface ​

Answer 1

Answer:

Friction depends on:-

* Roughness/smoothness of the sliding object.

* Roughness/smoothness of the surface.

* Shape/design of the object.

* Normal force acting upon the sliding bodies.

* Dry friction is independent of the surface area of a contact.

* Type of friction involved(rolling/sliding)

* Sliding surface's state of matter (solid/fluid)
