Why it is easy to push two wooden slabs one over other and why is it difficult to push two glass slabs one over other?

when a body actually moving over surface of another body friction is replace by kinetic friction

coeff. of knetic friction= fk / R

R normal reaction

If two surface are in contact then there pushing over same or other material depend upon the Coeff. of kinetic friction.
Cause there is a force act between those two objects and there motion depend on the kinetic friction

As we know that the coeff. of kinetic friction between wood and wood is 0.25
And in between the glass and glass is 0.9- 0.1

So its easy to push a wood over wood
then a glass over glass .

Nikki57: sry but it is a complicated lang,can u tell me in short and simple lang.Actually i know the answer but i m asking u.
Anonymous: Hey !! according to me and physics there is force of friction act between two objects if we slide them on each other . and to know that any body can easily slide or not ... we calculate Coefficient of kinetic friction betweem them
Nikki57: kk
Nikki57: it is because vaccume is created?

Nikki57: wt to tell?
Nikki57: isn't it because vaccume is created?
