because in rolling friction..we have wheels which help object to move faster by reducing friction
while sliding friction may involve any sort of pushing force in which friction is greater than force we apply

The force of friction depends upon the area of contact between the two surfaces. Rolling friction is the force resisting the motion when a body rolls on a surface. On the other hand Sliding friction is the force resisting the motion when a body slides on a surface. Therefore the area of contact is less in the case of rolling than in the case of sliding,So..., rolling friction is less than the sliding friction.
