Question

name or tell any one factor that affect friction​

Answer 1

Answer:

Factors that affect friction - example

Friction between two surfaces depends on the smoothness of the surfaces in contact. A greater force is required to move the surfaces past each other when they are rough as compared to when they are smooth.

Answer 2

$\huge\star{\underline{\mathtt{\red{A}\pink{n}\green{s}\blue{w}\purple{e}\orange{r}}}}$

a) Friction depends on the smoothness or roughness of the two surfaces which are in contact with each other.

b)When the two surfaces in contact are very rough, then the friction between them will be very large because the interlocking of very rough surface is too much.
