Naturally, rough surfaces have large force of friction. For example, a person can walk perfectly on rough surface. Here in the first image, the surface under the object is rough. So that we can observe that the object moves slow due to less application of force and rough surface.
Naturally, smooth surfaces have less force of friction. Here in the second image the surface under the object is smooth then the object moves very fast due to large application of force and smooth surface. From this we can conclude that force of friction is inversely proportional to amount of force applied on the body.
Here in the third image there are no wheels for the object so that man should apply large force to move the object for particular destination irrespective of surface.
We know that wheels reduce friction by allowing the contacting surface to roll rather than to drag or slide over each other. By reducing friction a wheel can enable you to use less force to move an object. Here in this image the object is provided with wheels which can reduce friction so that man uses less force when compared with the force applied by the man on the object without wheels to the same particular destination.
