It doesn't quite work that way. You don't specify the coefficient of friction for "glass", or from "wood", etc.; you specify the coefficient of friction between a PAIR of substances, sometimes also including any substance in between, such as lubricants. For example, you would specify the coefficient of friction:* Between glass and glass (dry)
* Between glass and glass (wet)
* Between glass and wood
* Between wood and wood
* Between tiles and leather (this might be interesting, since shoes are often made out of leather)
etc.
It is very rough. But please note that "coefficient of friction" isn't specified for a single substance. Rather, it is specified for the COMBINATION of two different surfaces. It must also be specified if some lubricant is used. For example sandpaper on sandpaper, sandpaper on glass, glass on glass (dry), glass on glass (wet), etc.
It doesn't work that way - friction is not something that is "produced". The way it works is that you have a coefficient of friction for two surfaces that are in contact. Then you use that coefficient of friction, and multiply it by the normal force, to calculate the actual FORCE of friction.For the coefficient of friction, you need to specify a PAIR of substances; for example, carpet against glass would probably have less friction than carpet against rubber.
Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.

Objects which cause little amount of friction are smooth objects such as glass and other objects which are man-made (most of the time). However, there are many objects which are natural which can create minimal amounts of friction too.answ2. Very often, using two different materials will give superior wear characteristics - = low friction. e.g. White metal bearings against steel, Steel against wood (in ship's prop shafts).I'd expect glass against glass to have a high friction coefficient.

Sandpaper can be made with sand, but carborundum is more common. Glass is made from a mixture including sand.
yes or no, pili ka na lang
Glass paper is made of glass and is more rough and sandpaper is made of sand which is less rough
If less work is needed, it may be because there is a lower amount of friction between the glass and the cart.

Rub it with very fine sandpaper (400+)
Use a glass cutter to cut the bottle top off the bottle, use sandpaper to smooth the edges of the glass.
