front 1 Air | back 1 It is all around us, we need it to breathe, but we can't really see it, yet we can for surely feel it. |
front 2 Fluid | back 2 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. |
front 3 Pressure | back 3 The weight or force that is produced when something presses or pushes against something else. |
front 4 Density | back 4 The amount of mass in a specified space. |
front 5 Buoyancy | back 5 The ability to float. |
front 6 Lift | back 6 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. |
front 7 Thrust | back 7 The force that moves a plane forward through the air. Thrust is created by a propeller or a jet engine. |
front 8 Weight/Gravity | back 8 A force that acts on the plane to pull it back to earth or pull it down. |
front 9 Drag | back 9 The air resistance that tends to slow the forward movement of an airplane. |
front 10 Bernoulli's Principle | back 10 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. |
front 11 Aerodynamic | back 11 The science of moving through the air. |
front 12 Aileron | back 12 The sections of the wing that can move up or down and control the roll of the airplane. |
front 13 Airfoil | back 13 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). |
front 14 Rudder | back 14 The vertical stabilizer on an aircraft. It controls the YAW of the plane. The hinged section of the airplane. |
front 15 Elevator | back 15 The horizontal stabilizers, or the part of the airplane that controls pitch. |
front 16 Yaw | back 16 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. |
front 17 Pitch | back 17 The direction of the NOSE of the airplane. It determines whether the airplane is climbing or diving. The elevators, or horizontal stabilizers, control this. |
front 18 Roll | back 18 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. |
front 19 Fuselage | back 19 The main body of the airplane. |
front 20 Wings | back 20 The main item on airplanes that allow them to fly, an adaptation of birds and insects that allow them to fly. |
front 21 Aircraft | back 21 A machine that is able to fly by taking off from the earth and overcoming weight or gravity to create lift. |
front 22 Spacecraft | back 22 A vehicle or machine designed to fly in outer space. |
front 23 Rust | back 23 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. |
