Basically to reduce air friction on a body, the most general idea is to streamline the body. The same is done by the helmet. When one drives a bike , the person takes a position which streamlines the flow of air over the body(i.e, he bends, like in motoGPs). But the head is not so streamlined and it can obstruct the air flow and hence can add additional drag. The helmet is also designed in the same way(take a look at the design of helmet of cyclists), it is streamlined, so that now the air flows smoothly over the head portion, hence reducing the drag.

No, it is a protein found in tissue to reduce friction
Why do snow borders wax their skies?
To reduce friction, so they go faster.
What might parachutists do to speed up their rate of fall?
They would have to reduce friction by becoming perpendicular to the ground and reduce their surface area.
Cars airplane wings and bike helmets are built in a streamlined shape to reduce what?
Friction.
Does sand reduce friction?
No, sand does not reduce friction but increase friction.
Do helmets reduce the number of bike accidents in the United States?
No bike helmets don't reduce the number of bike accidents, but they do reduce the serious injuries related to the accidents. Bike helmets save lives.
How can you reduce and increase friction?
Lubrication to reduce friction. To increase friction step on the brakes.
Do wheels reduce friction?
yes because when they brake the friction is caused to reduce
What are the ways of increasing and reducing friction?
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
What kind of friction can help reduce friction?
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
How does oil reduce air friction?
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
What are the factors that reduce in case of friction?
the factors that reduce in case of friction are the velocity and acceleration.
What does a bit of oil reduce in science?
Oil is used to reduce friction.
What kinds of substance reduce friction?
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.
What are the ways in which friction is reduce on aeroplane?
by giving it better aerodynamics you can reduce friction. but also the faster it goes the more friction it gets.
