1) The Bernoulli effect says that the faster air moves the lower the air pressure. And when a wind cuts through air the wind on the top moves faster that the air on the bottom causing the air under the wing to create lift. The Newton Theory believes that the wing of the airplane skips along the air.



2)

Yaw- an angle, to the right or left, determined by the direction of motion of an aircraft or spacecraft and its vertical and longitudinal plane of symmetry.

Pitch- to deviate from a stable flight attitude by oscillations of the longitudinal axis in a vertical plane about the center of gravity.

Roll- Aviation. to deviate from a stable flight attitude by rotation about its longitudinal axis.

Dihedral- the angle at which the right and left wings or the halves of any other horizontal surface of an airplane or the like are inclined upward or downward.

Static- not active, or not going to chance.

Dynamic- of or pertaining to force or power.

Aerodynamic- the branch of mechanics that deals with the motion of air and other gases and with the effects of such motion on bodies in the medium.
