A hovercraft use a cushion of air to reduce friction.
In extreme engineering applications there are also air bearings, bearings where a steady flow of air acts as a lubricant between two very finely machined surfaces to keep them apart.

Give ways to decrease friction?
Its reduce by following ways By polishing the surface use lubricants by streamlining by air cushion by converting sliding friction in to rolling friction
What features on modern cars that help reduce air friction?
tryt
What do lugers wear to reduce air friction?
A luger wears a skin tight race suit and smooth boots to reduce air friction. Their helmet is aerodynamic and smooth and it has a visor that extends below the chin to eliminate air pockets.
How do skiers reduce friction?
Friction between skis and snow may be reduced by waxing the skis. Air friction is reduced by tucking the body into a streamlined position.
What is an air cushion?
An air cushion is a layer of trapped air which supports a hovercraft.
How does an air cushion reduce friction in hovercrafts?
As the air cushion is inflated, the area of contact with the surface is very less.As a result, the friction is less.
How does the flow of air reduce friction of the hovercraft in motion?

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.
Is hovercraft and a maglev train similar?
They are similar only in that they both aim to reduce the friction that come from the vehicle moving over the water or rails. The means is quite different. The hovercraft uses a cushion of air and the maglev uses the repulsive force of a magnetic field.

What features on modern cars help reduce air friction?
The most common features in modern cars that help to reduce air friction is the streamlined design of the bumpers and spoilers. The streamlined shape of fast cars also helps to reduce drag.
What objects are streamlined to reduce friction by air resistance?
like deflectors on lorries
What force do skin tight ski pants reduce?
air drag
Why do car makers try to make their cars streamlined?
To reduce air friction.
How can you make a pendulum swing without stopping Is it possible?
Every time the pendulum swings back and forth, some energy is lost to friction. Friction with air, and friction in the supporting string or whatever. If you manage to reduce this friction (for example, reduce air friction by making the pendulum swing in a vacuum), it will swing longer. However, you won't be able to reduce energy losses completely; it may swing longer, but not forever.
