Aircrafts and aerodynamics
The main parts of an aircraft are:
- the fuselage,
- the wings,
- the horizontal stabilizer,
- the vertical stabiliser,
- the landing gear, and
- of course the engine(s)

Four Forces on an Airplane
The four forces which act upon an aircraft in flight are:
- LIFT acts upwards at right angles to the airflow through the centre of pressure. In simple terms, Lift is perpendicular to the Relative Wind.
- DRAG is the backward force which opposes the forward motion of the aircraft and acts parallel and in the reverse direction to the aircraft movement.
- THRUST is the forward propulsive force provided by the engines.
- WEIGHT is the total weight which acts vertically downwards through the centre of gravity.
- LIFT<up and down>WEIGHT
- THRUST<forward and back>DRAG
NASA's Beginners Guide to Aerodynamics - Supplement your of study aerodynamics at your own pace and to your own level of interest. Some of the topics included are: Newton's basic equations of motion; the motion of a free falling object, that neglects the effects of aerodynamics; the terminal velocity of a falling object subject to both weight and air resistance; the three forces (lift, drag, and weight) that act on a glider; and finally, the four forces that act on a powered airplane. There are many interactive pages designed to illustrate aerodynamics.
