The word ‘Aerodynamics’ is originated from the Greek word aero means related to air and dynamics means motion. So, collectively aerodynamics means the study of motion of air. It is the way air moves around things. In simple words, aerodynamics is related to the flow of air around a projectile which can influence speed and direction of the object.
Basic forces of Aerodynamics
(a) Lift /Air Resistance: It is the force that pushes the object to move upward.
(b) Weight /Head Wind: It is the force generated by the gravitational attraction of the earth.
(c) Drag /Tail Wind: It is a force that tries to slow the object down
(d) Thrust: It is the force that is opposite of drag.
