Question

what are the different types of friction?

Answer 1

there are three types of friction static, rolling and sliding
in static friction the force which is required to overcome friction at the instant an object starts moving from rest is a measure of static friction and
sliding friction the force of friction between the two surfaces in contact when one of them just slide over the other is called sliding friction

and rolling friction the force of friction between the two surface in contact when one of them is rolling on the other is called rolling friction

Answer 2

Their are three types of friction
Static friction : The force required to overcome friction at instant an object starts moving from rest is a measureof static friction.
Sliding friction : The force of friction between the two surfaces in contact when one of them just slide over the other is called sliding or kinetic friction.
Rolling friction : The froce of friction between the two surfaces in contact when one of them is rolling is called rolling friction.
