## What is the full meaning of airplane?

(ˈɛərˌplein) noun. 1. a heavier-than-air aircraft kept aloft by the upward thrust exerted by the passing air on its fixed wings and driven by propellers, jet propulsion, etc.

## How do you describe a airplane?

An airplane is a flying vehicle that has fixed wings and engines or propellers that thrust it forward through the air. It’s most common when you travel long distances to take an airplane. … Commercial airplanes are flown by a pilot and staffed by a crew.

## What is a plane short answer?

In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.

## Why is it called an airplane?

Etymology and usage

First attested in English in the late 19th century (prior to the first sustained powered flight), the word airplane, like aeroplane, derives from the French aéroplane, which comes from the Greek ἀήρ (aēr), “air” and either Latin planus, “level”, or Greek πλάνος (planos), “wandering”.

## What is a plane in math definition?

A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors. The generalization of the plane to higher dimensions is called a hyperplane. The angle between two intersecting planes is known as the dihedral angle.

## What are airplanes called?

airplane, also called aeroplane or plane, any of a class of fixed-wing aircraft that is heavier than air, propelled by a screw propeller or a high-velocity jet, and supported by the dynamic reaction of the air against its wings.

## What is an airplane kid definition?

The term airplane, which is often shortened to plane, usually refers to any type of power-driven aircraft that has fixed wings and is heavier than air. An airplane moves through the air with the help of its engine and wings. The wings are shaped in a particular way so that air flows over them and gives them lift.

## Is a jet an airplane?

A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. … In August 1939 the turbojet powered Heinkel He 178, the world’s first jet aircraft, made its first flight.

On December 17, 1903, Wilbur and Orville Wright made four brief flights at Kitty Hawk with their first powered aircraft. The Wright brothers had invented the first successful airplane. The Wrights used this stopwatch to time the Kitty Hawk flights.

## What is the best description of a plane?

A plane is a flat surface that extends forever in two dimensions, but has no thickness. Planes have no edges to them.

## What is a airplane made of?

Most airplanes today are made out of aluminum, a strong, yet lightweight metal. The Ford Tri-Motor, the first passenger plane from 1928, was made out of aluminum. The modern Boeing 747 is an aluminum airplane as well. Other metals, such as steel and titanium, are sometimes used to build aircraft.

## What is plane and example?

In geometry, a plane is a flat surface that extends into infinity. … A plane has zero thickness, zero curvature, infinite width, and infinite length. It is actually difficult to imagine a plane in real life; all the flat surfaces of a cube or cuboid, flat surface of paper are all real examples of a geometric plane.

## How do Aeroplanes fly?

Airplanes fly because they are able to generate a force called Lift which normally moves the airplane upward. Lift is generated by the forward motion of the airplane through the air. This motion is produced by the Thrust of the engine(s).

## What does an airplane do?

A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky.
