1

Air

card image

It is all around us, we need it to breathe, but we can't really see it, yet we can for surely feel it.

2

Fluid

card image

A substance, as a liquid or gas, that is capable of flowing and that changes its shape at a steady rate when acted upon by a force tending to change its shape.

3

Pressure

card image

The weight or force that is produced when something presses or pushes against something else.

4

Density

card image

The amount of mass in a specified space.

5

Buoyancy

card image

The ability to float.

6

Lift

card image

The upward force that is created by the movement of air above and below a wing. Air flows faster above the wing and slower below the wing, creating a difference in pressure that tends to keep an airplane flying.

7

Thrust

card image

The force that moves a plane forward through the air. Thrust is created by a propeller or a jet engine.

8

Weight/Gravity

card image

A force that acts on the plane to pull it back to earth or pull it down.

9

Drag

card image

The air resistance that tends to slow the forward movement of an airplane.

10

Bernoulli's Principle

card image

The air moving over an airfoil travels faster over the top creating a lower pressure than the air that is traveling slower on the bottom. The air on the bottom of the airfoil is traveling slower and creating a higher air pressure resulting in lift.

11

Aerodynamic

card image

The science of moving through the air.

12

Aileron

card image

The sections of the wing that can move up or down and control the roll of the airplane.

13

Airfoil

card image

The shape of a wing or blade (of a propeller, rotor, or turbine) that helps to create lift in either man-made things, or in nature (birds).

14

Rudder

card image

The vertical stabilizer on an aircraft. It controls the YAW of the plane. The hinged section of the airplane.

15

Elevator

card image

The horizontal stabilizers, or the part of the airplane that controls pitch.

16

Yaw

card image

The direction the airplane is flying. It either flies straight, banks to the left or banks to the right. The rudder, or vertical stabilizer, controls this.

17

Pitch

card image

The direction of the NOSE of the airplane. It determines whether the airplane is climbing or diving. The elevators, or horizontal stabilizers, control this.

18

Roll

card image

The ailerons control this.

To roll the aircraft to the right, the LEFT aileron must be UP and the RIGHT aileron must be DOWN.

To roll the aircraft to the left, the RIGHT aileron must be UP and the LEFT aileron must be DOWN.

19

Fuselage

card image

The main body of the airplane.

20

Wings

card image

The main item on airplanes that allow them to fly, an adaptation of birds and insects that allow them to fly.

21

Aircraft

card image

A machine that is able to fly by taking off from the earth and overcoming weight or gravity to create lift.

22

Spacecraft

card image

A vehicle or machine designed to fly in outer space.

23

Rust

card image

The formation of reddish-brown ferric oxides on iron because of the presence of water - in other words, the breaking down of iron due to water.

24

What is the different between aircraft and spacecraft?

card image

  • wings

25

What are the 6 principles of air?

  1. Air exerts pressure
  2. Air is everywhere
  3. Air takes up space
  4. Air has weight
  5. Air can be condensed
  6. Air acts like a fluid
