Question

Please arrange the frictions in their increasing orders 1.static friction 2.sliding friction 3.rolling

Answer 1

Decreasing Order  of frictional forces :
Static friction >Sliding Friction > Rolling friction
••••••••••

EXPLAINATION:

Frictional force are of three types :
1.static friction
2.Sliding friction
3.Rolling friction 
Static friction : Static friction comes into play when when one object is at rest with respect to other object.
Irregularities will be more. Hence force required to overcome static friction is more.

Sliding friction comes into play when one objects slides over the surface of other objects.
Less time is given for the irregularities to interlock as object slides .

Rolling friction comes into play when one object rolls over the surface of the other.

Decreasing Order  of frictional forces :
Static friction >Sliding Friction > Rolling friction

Answer 2

Static friction<Rolling friction<Sliding friction
