Air
![card image](../uploads/733/67/5cde6158_14d9e05fff9__8000_00000447.jpg)
It is all around us, we need it to breathe, but we can't really see it, yet we can for surely feel it.
Fluid
![card image](../uploads/732/66/5cde6158_14d9e05fff9__8000_00000449.jpg)
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.
Pressure
![card image](../uploads/734/68/5cde6158_14d9e05fff9__8000_00000441.png)
The weight or force that is produced when something presses or pushes against something else.
Density
![card image](../uploads/735/69/5cde6158_14d9e05fff9__8000_00000445.jpg)
The amount of mass in a specified space.
Buoyancy
![card image](../uploads/736/70/5cde6158_14d9e05fff9__8000_00000443.jpg)
The ability to float.
Lift
![card image](../uploads/737/71/5cde6158_14d9e05fff9__8000_00000423.jpg)
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.
Thrust
![card image](../uploads/738/72/5cde6158_14d9e05fff9__8000_00000417.jpg)
The force that moves a plane forward through the air. Thrust is created by a propeller or a jet engine.
Weight/Gravity
![card image](../uploads/739/73/5cde6158_14d9e05fff9__8000_00000421.jpg)
A force that acts on the plane to pull it back to earth or pull it down.
Drag
![card image](../uploads/740/74/5cde6158_14d9e05fff9__8000_00000419.jpg)
The air resistance that tends to slow the forward movement of an airplane.
Bernoulli's Principle
![card image](../uploads/741/75/5cde6158_14d9e05fff9__8000_00000415.png)
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.
Aerodynamic
![card image](../uploads/742/76/5cde6158_14d9e05fff9__8000_00000413.png)
The science of moving through the air.
Aileron
![card image](../uploads/743/77/5cde6158_14d9e05fff9__8000_00000425.png)
The sections of the wing that can move up or down and control the roll of the airplane.
Airfoil
![card image](../uploads/744/78/5cde6158_14d9e05fff9__8000_00000439.png)
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).
Rudder
![card image](../uploads/745/79/5cde6158_14d9e05fff9__8000_00000429.jpg)
The vertical stabilizer on an aircraft. It controls the YAW of the plane. The hinged section of the airplane.
Elevator
![card image](../uploads/746/80/5cde6158_14d9e05fff9__8000_00000437.jpg)
The horizontal stabilizers, or the part of the airplane that controls pitch.
Yaw
![card image](../uploads/747/81/5cde6158_14d9e05fff9__8000_00000433.jpg)
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.
Pitch
![card image](../uploads/748/82/5cde6158_14d9e05fff9__8000_00000435.jpg)
The direction of the NOSE of the airplane. It determines whether the airplane is climbing or diving. The elevators, or horizontal stabilizers, control this.
Roll
![card image](../uploads/749/83/5cde6158_14d9e05fff9__8000_00000427.png)
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.
Fuselage
![card image](../uploads/750/84/5cde6158_14d9e05fff9__8000_00000411.jpg)
The main body of the airplane.
Wings
![card image](../uploads/751/85/5cde6158_14d9e05fff9__8000_00000409.jpg)
The main item on airplanes that allow them to fly, an adaptation of birds and insects that allow them to fly.
Aircraft
![card image](../uploads/752/86/5cde6158_14d9e05fff9__8000_00000405.jpg)
A machine that is able to fly by taking off from the earth and overcoming weight or gravity to create lift.
Spacecraft
![card image](../uploads/753/87/5cde6158_14d9e05fff9__8000_00000403.jpg)
A vehicle or machine designed to fly in outer space.
Rust
![card image](../uploads/754/88/5cde6158_14d9e05fff9__8000_00000401.jpg)
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.
What is the different between aircraft and spacecraft?
