Static friction is always greater than sliding friction. Static friction is the type of friction that exists when two objects touch eachother at rest. Sliding friction is just like it sounds, when the objects are touching, but in motion. ...........................

when a box start sliding <the contact point of the irregularities do not get enough time to lock between the surface of The floor. That is why sliding friction is less than static friction tht is why u will find it easier to pull a box in motion than 2 get it started. nnnnnnnnnnn 1 thing is also i didnt hav copied this from pratiksha is cumin in my exams.

the force required to overcome friction at the instant an object starts moving rest is a measure of static friction.on the other hand ,the force required to keep the object moving with the same speed is a measure of sliding friction .when the box starts sliding the contact point on its surface, do not get enough time to lock into the contacts points on the floor.so,the sliding friction is slightly smaller than the static friction.

Slinding friction- when one body slides over other body
Static friction-when an object starts moving to overcome friction is called static friction.
Sliding is simple to overcome friction as it just slides without much interlockings as time is less but in static we have overcome interlockings between 2 surafaces...
Hope it helps..

Friction comes to play when irregularities present in the surfaces of two objects in contact get interlocked with each other. In sliding friction,the time given for interlocking is very small. Hence,interlocking is not very strong. Therefore, less force is required to overcome this interlocking. Because of this sliding friction is less than static friction

time to lock into the irregularities on the surface of the other object completely. Since the interlocking of the
two surfaces is less when an object has already started moving, therefore, the sliding friction is smaller than
the static friction.
It is always easier to roll than to slide an object over another object. So, rolling friction is much less than
sliding friction.

In sliding friction if we slide any object from the slope it will be easier to bring it but in static friction there we have to slide the object on an irregular surface which is not easier to bring it..
So,the relation between sliding friction and static friction is given below-
Static friction>Sliding friction>Rolling friction
