Do rough objects have more or less friction that smooth objects?

Kids, DO TRY THIS AT HOME! Find out by experimenting :D
Take once of your school textbooks (one of the heavy ones work nicely) and place it flat on your kitchen table. Try to push it away from you with one finger.
Are you pressing against the book very hard?
Now take the same textbook, and place it on your living room carpet (the same way you did on the kitchen table).
Try to push it again with one finger. Do you think it took more force to move the book across the carpet, compared to the tabletop?
Cliffnotes version: The short answer is that rough objects have more friction, or rather, are affected by friction more than smoother ones. (but try the experiment yourself and see!)

Why is it easy to push a car on a smooth road than on a rough road?
this is because there is less friction on the smooth road than on the rough, ( friction is the force that opposes movement) hope this helps
What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Why do smooth surfaces produces less friction than rough surfaces?
Because there is less traction for an object to grab onto on a smooth surface rather than when an object runs over a rough surface.
Do snails move faster on rough surfaces or smooth surfaces?
Snails move faster on rough objects as the sticky liquid they use for locomotion gets good friction and helps it to move. But on rough surfaces, the frictional force is much less and the snail can hardly move.
Does rough surfaces exert greater friction?
Yes. Think about two steep hills. One is covered in ice (smooth). The other is covered in sandpaper (rough). The ice covered hill would be MUCH easier to slide down. Thus, the friction is much LESS, on a SMOOTH SURFACE. Then the opposite must be true, that friction is GREATER on a ROUGH SURFACE.

Is the amount of friction greater between rough surfaces smooth?
smooth surfaces have less friction, take an ice rink for example, the resistance on that is less than the resistance on asphalt
How does an object move on a rough and on a smooth surface?
It is on smooth surfaces because the amount of friction is less.
Why does a ball stop rolling on rough road sooner than on a smooth road?
Because the rough road has more friction, thus expending the balls energy quicker than smooth road with less friction.
Why friction does not occur in smooth surfaces?
It is wrong to say that friction doesn't occur in smooth surface.. As ideally, no such surface exists, which has 0 value of friction. We can say that the magnitude of friction force is less in smooth surfaces as compared to that in rough surfaces. Friction opposes the motion of a body. When we go to the molecular level, we can see that the surface of a plane is not smooth but rough.. We cannot see that roughness through naked eyes. But the amount of roughness differs from object to object. The so called smooth surfaces have less roughness as compared to un-smooth surfaces. Hence, the magnitude of friction is LESS in smooth surfaces...

Is the amount of friction greater between rough surfaces or or smooth surfaces?
rough surfaces because it has more bumps that stop it from moving faster

Snails move faster on rough objects as the sticky liquid they use for locomotion gets good friction and helps it to move. But on rough surfaces, the frictional force is much less and the snail can hardly move.
Does it matter how smooth or rough an object is to determine the amount of friction applied to an object?
yes a object will have less surface area than if it is smooth
