− | Drag is a [[force|mechanical force]] that opposes the motion of a body like an [[aircraft]] that travels in a fluid medium. The force arises from the interaction between the body and the fluid medium. The difference in the velocities of the two entities results in drag. When the free airflow encounters an [[airfoil]] it exerts an aerodynamic force on it due to the combined effect of [[force#Newton's laws of motion|newton’s third law of motion]] and [[Bernoulli’s principle]]. When this resultant force is resolved, the horizontal component is the drag and the vertical component is the | + | Drag is a [[force|mechanical force]] that opposes the motion of a body like an [[aircraft]] that travels in a fluid medium.

When the free airflow encounters an [[airfoil]] it exerts an aerodynamic force on it due to the combined effect of [[force#Newton's laws of motion|newton’s third law of motion]] and [[Bernoulli’s principle]]. When this resultant force is resolved, the horizontal component is the drag and the vertical component is the lift as shown in [http://swyde.com/s/images/3/3c/Lift-and-drag-airfoil.svg this figure]. The most common type of drag is the skin friction drag. The shape of the object also influences these factors much and contributes to the drag component as form drag and interference drag. The other forms of drag are induced drag and wave drag. |
