| accelerate | to speed up |
| aerodynamics | a field of fluid dynamics that studies how gases flow and forces act upon objects moving through the air |
| aeronautics | a study of flight/the science of building and operating an aircraft |
| airflow | the motion of air molecules flowing around an object, such as a wing |
| ailerons | control surfaces on the trailing edge of wing |
| axis | a straight line, through the center of gravity, around which an aircraft rotates |
| air pressure | the force created by air pushing on a surface |
| altitude | height of an object, like an airplane, above sea level or the earth's surface |
| angle of attack | the angle of a wing to the oncoming airflow |
| Bernoulli's Principle | the faster molecules within a fluid move, the less pressure they exert on objects around them/which applies to water, air and gases |
| drag | the force that resists the motion of the aircraft through the air |
| elevators | control surfaces on the horizontal part of the tail that are used to make the airplane pitch |
| empennage | the parts of the airplane located at the tail end |
| engine | a machine that used combustion to create energy |
| fin | another word for the vertical portion of the tail |
| flaps | moveable parts of the trailing edge of the wing used to increase lift at slower air speeds speeds |
| force | a push or a pull in a certain direction, that can be measured |
| fuselage | the part of an airplane to which the empennage and wings are attached |
| gravity | the natural force that pulls an object toward the earth |
| horizontal stabilizer | the horizontal part of the tail |
| instruments | tools used to observe, measure and control |
| landing gear | another word for undercarriage |
| lift | a force that is perpendicular to the airflow around an aircraft |
| pitch | a rotational motion in which an airplane turns around its lateral axis |
| pressure | a force being exerted on part of a surface |
| pull | to use force to bring something closer |
| push | to use force to move something ahead or to the side |
| roll | a rotational motion in which the aircraft turns around its longitudinal axis |
| rudder | a control surface on the trailing edge of the vertical part of the tail that is used to make the aircraft yaw |
| spoiler | a device for changing the airflow around a wing to destroy lift, normally located on top of the wing |
| stabilizer | a surface that helps to provide stability for an aircraft |
| stall | a breakdown of the airflow over a wing, suddenly reducing or destroying lift |
| thrust | a force created by the engines that pushes an aircraft through the air |
| velocity | the speed of an object, in a certain direction |
| weight | a force of gravity acting on an object |
| lateral axis | the axis extending through the center of gravity of an aircraft and parallel to a line donnecting the tips of the winds |
| longitudinal axis | the axis extending through the center of the fuselage from the nose to the tail |
| yaw | a rotational motion in which the aircraft turns around its vertical axis |
| vertical axis | the axis extending straight up and down through the center of gravity of an aircraft |
| airplane | an aircraft that used the force of air on it's wings (called lift) to fly |
