Viscous drag on the movement of the falling body due to air medium
Air- resistance is basically a type of friction between an object and the air
Air in the upper atmosphere speeds up.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
Rolling friction is the force of friction between two surfaces when one surface rolls over another.Sliding friction is the force of friction between two surfaces when one surface is moving on another.
Viscous drag on the movement of the falling body due to air medium
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.

Friction between the the luge and the ice.
it will be slower near the surface
The wind at the surface of the ground where the molecules are having friction is moving slower than the wind above the surface.
the rougher the surface is, the more friction there will be
Well.. There is surface friction from the tires on the road, there is air friction from the bike itself ,, more air surface friction if your on it.. Then there is mechanical friction through the resistance of the, chain, bearing assembly grease in axle.
Air in the upper atmosphere speeds up.
There is friction between the tires and the surface they're being driven on. Friction creates heat, which is transferred to the air inside the tires. When the air is heated in such a manner, it expands.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
upper earth (atmosphere)For computer answer A+ air near the earth's surface blows more slowly.
