An air cushion is a layer of trapped air which supports a hovercraft.
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.
Stupid la you
There are fans in the hovercraft that direct air downwards. The air is 'trapped' by the flexible skirt around the edge of the craft - this creates a cushion of air strong enough to allow the craft to float.
Under the playing surface is a system of fans to circulate air. The playing surface itself has tiny holes which allows the air to escape evenly, providing a constant 'cushion' for the puck to ride on.
Because there is more space for air to cushion its falling.
An air-cushion vehicle is an alternative name for a hovercraft.
Air cushion vehicles work by creating a large force of that points to the ground. This lifts the vehicle off the ground letting it ride on a cushion of air.
it rides on an air cushion so it can go on water, land, snow ect.
A vehicle that travels over water or land on a cushion of air is called a hovercraft
on a cushion of air
A hovercraft is an air cushion vehicle which floats on a cushion of air. Their power source can sometimes be gasoline or sometimes electricity.
As the air cushion is inflated, the area of contact with the surface is very less.As a result, the friction is less.

Referred to as a Hovercraft.

To prevent bed sores.
There air propelers at the bottom that keep it floating
