Friction is phenomenon you see between two rough surfaces. A slippery liquid or lubricants when applied, coats over these rough surfaces creating a layer of the lubricant itself. Liquids like lubricants has very low viscosity, that is the sliding friction between two liquid layers, hence they easily slip over each other. In this way they help reduce friction.
yes it can also reduce friction especially when its slippery, cleats reduce the surface area that are in contact between the shoes and the ground surface?
all you have to do is add something slippery e.g oil
Lubricant (Liquids, oils, grease, fats, water, graphite...)
Actually, waxing skis increases friction. Wax is not slippery. If you wanted less friction you could oil your skis.
Because if there is less friction, the road would be very slippery, therefore more dangerous

Lubricants.
because it needs to be able to reduce friction between bones
cartilage

aerodynamic exteriors to make them more slippery in the wind.
