A hovercraft use a fan to push air underneath the craft and create an air cushion, and on a specially designeg skirt to keep the air cushion contained. The hovercraft will then be suspended with virtually no ground contact by that cushion, pretty much regardless of the speed it's moving at.
An air boat at speed might manage to ram some air underneath its hull due to the wide, upturned front, but will settle solidly onto the ground the moment it slows down.

What is the German word for hovercraft?
Hovercraft is das Luftkissenboot in German (lit. air cushion boat)
What is difference between hovercraft and aircraft?
Basically, an aircraft flies, a hovercraft doesn't. An aircraft relies on aerodynamic lift, a hovercraft is "lifted" by a cushion of pressurised air trapped in the plenum chamber.
What boat travels over water on a cushion of air?
That would be a hovercraft. However, hovercraft are not really boats and can travel on both land and water.
What is the same between a plane and a hovercraft?
flying air.
What kind of boat float along on air?
A hovercraft is a type of boat that floats along on a cushion of air. It uses fans to create the air cushion beneath the boat, allowing it to glide over both land and water surfaces.
What is the principle of hovercraft?
Air fills the skirt, and the thin layer of air escaping the skirt creates a nearly frictionless layer between the craft and the ground. Another fan, much like an air boat, propels the craft forward
How does a hovercraft float on a cushion of air?
A hovercraft floats on a cushion of air created by a fan or propeller underneath the craft. This cushion of air reduces friction between the hovercraft and the ground, allowing it to glide smoothly over surfaces such as water, ice, or land. The pressure from the cushion of air supports the weight of the hovercraft, enabling it to "float" above the surface.
How does a hovercraft use static friction?
A hovercraft uses static friction to create a cushion of air underneath it, allowing it to hover above the surface. The static friction between the air cushion and the ground helps the hovercraft move smoothly and efficiently. By controlling the amount of air pressure and distribution, the hovercraft can maneuver in different directions.
Who does a hovercraft reduce the effects of drag between it and the water?
A hovercraft reduces the effects of drag between it and the water by creating a cushion of air underneath it. This cushion of air lifts the hovercraft slightly above the water's surface, reducing friction and allowing the craft to move more easily and efficiently.
Why do things go faster underwater then on the surface?
Because a hovercraft rides on a cushion of air, there is less contact between a hovercraft and water, so there's less friction to slow it down as compared to a regular watercraft.
What is the difference between air crafts and air planes?
The word aircraft - refers to any vehicle capable of flight - of which are hovercraft, gliders, planes and helicopters. The word airplane - relates only to fixed-wing aircraft.
What forces act on a hovercraft?
The main forces acting on a hovercraft are lift, propulsion, and drag. Lift is generated by the cushion of air under the hovercraft, propulsion is produced by the engines to move the hovercraft forward, and drag is the resistance encountered as the hovercraft moves through the air or water.
