Question

how friction gets affected by the nature of the surface​

Answer 1

$\huge\mathfrak\red{Answer}$

WHAT IS FRICTION ?

YOU NOTICE MANY TIMES WHEN YOU ROLL A BALL OVER ANY SURFACE THAN AFTER SOMETIME THE BALL STOP ROLLING SO WHAT'S THE REASON BEHIND IT. THE REASON IS FRICTION

WHEN YOU USE TO WATCH THE SURFACE OF DIFFERENT MATERIALS WITH MICROSCOPE THAN YOU FIND THAT THERE ARE SMALL GRADES OVER THE SURFACE OF THE MATERIAL.

WHEN TWO SURFACE TOUCHE EACH OTHER THAN THESE GRADES GET INTERLOCKED WITH EACH OTHER AND TENDS TO STOP THE MOVING SURFACE.

DIFFERENT TYPE OF MATERIAL HAVE DIFFERENT GRADES OVER ITS SURFACE THATS WHY FRICTION GET AFFECTED BY THE NATURE OF THE SURFACE.

MATHEMATICAL.

$mathematically \: friction \: is \: equal\\ to \: \gamma n \\ \\ where \: \gamma \: represent \: the \: nature \: of \: the \\ material \: or \: surface \\ where \: as \: n \: represent \: the \: force \\ with \: which \: both \: surface \: press \: \\ eachother$

Answer 2

Answer:

A friction depends on the nature of surface in contact for a given pair surfaces friction depends upon the state of smoothness of those surfaces . friction depends on how hard the two objects press together.
