Yes, clay does have more friction than sandpaper. This is because, clay is a much heavier object/material then sandpaper, therefore if you were to drag a lump of clay on the floor and measured the friction, it would be higher then the amount of friction caused by sandpaper. If the amount of force needed to pull the clay is larger then the amount of force needed to pull the sandpaper, that means that there is a much larger amount of friction present, because the more friction there is present, the harder you would need to pull.
Hope this helps.

Does a tire or pulley have more friction?
A tyre has more friction than a pulley.
What is the Defintion of sliding friction?
Sliding friction is when two objects slide across from one another. An example is sliding a book across a desk. It is also known as Kinetic friction.Sliding friction is friction caused by an object sliding over another surface.
It usually take more force to start an object sliding than it does to keep an object sliding because static friction is usually than sliding friction?
usually greater than the sliding friction
What is the different between istatistic and kinetic friction?
I assume you mean static and kinetic friction. Static friction tends to be stronger and less predictable. For example, if you start applying more and more force to a stationary brick lying on sandpaper, it is almost impossible to predict when it will begin to move. Once it is moving, however, you can get a pretty consistent estimate for how much drag the brick is experiencing (kinetic friction). Modern cars have computers monitoring the brakes. If you slam on your brakes, the computer will loosen up the brakes to prevent you from skidding. This is because static friction is more effective than kinetic friction, and once you start skidding out you have lost most of your braking power.
Does ice has a higher coefficient of friction than rubber does?
Rubber has more friction than an ice cube. Ice has almost no friction what so ever.
How do you raise and lower frictional forces?
A rough surface like sandpaper will have more friction than a smooth surface. smoothing out a surface will reduce friction
Does friction depend on the nature of surface in contact?
Yes it does. That's why skating is a lot more fun on ice than on sandpaper.
What is friction affected by?
Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.
What is a good sentence for the word coarse?
I am looking for some sandpaper that is more coarse than this. My beard is no more than a coarse stubble, right now.
What causes wear and tear?
Consider rubbing your hand over waxed paper and over sandpaper and you will understand the reason that increased friction causes increased wear. Friction is esentially due to the un-smoothness of surfaces, even though this roughness, in many cases, may be microscopic. Two nearly perfectly smooth surfaces - teflon on teflon, for instance - will exhibit almost no friction, whereas two very rough surfaces - sandpaper on sandpaper - will exhibit enormous friction. The rougness, or raised bits of each surface cut into the other surface with the softer surface wearing away more quickly than the harder surface. Sandpaper on wood, for example, will wear away the wood surface first, but eventually the sandpaper itself will be worn to the point where it is no longer effective. This is an extreme example of friction, but it works the same on a microscopic level - say for instance the friction between an automobile's brake pad and the rotor, both of which, to the eye, appear quite smooth.
Does fluid friction have more friction than rolling friction?
yes
What surface would produce the greatist friction on an object?
Carpet has more friction than tile. Tile has more friction than ice.
Does a tire or pulley have more friction?
A tyre has more friction than a pulley.
Why does clay hold more water than sand and silt?
Clay is not more porous than sand. Porous means permeable by fluids, so, sand is more porous than clay.
Do seesaw need more friction or less friction?
than what?
Is sliding friction more than rolling friction?
Yes, sliding friction creates more thermal energy and wears down the two surfaces quicker than rolling friction.
Does rolling friction tend to oppose motion more than sliding friction does?
Generally, sliding friction is much stronger than rolling friction.
