Drag is one of the four forces applicable to a flying aircraft: thrust, drag, lift and weight. Drag is the amount of resistance to forward motion caused by a solid body moving through a fluid (air is considered a fluid for the purpose of aerodynamics).
The easiest way to feel the effect of drag is to stick one's arm out a car window while it's moving. First do it palm-down (horizontal), and then palm-forward (vertical). The force, known as "drag", pushing the arm backward increases substantially when the palm is vertical. That force is the same effect that an aircraft in flight experiences due to the frontal area of its airframe forcing its way through the air.
The science of aerodynamics seeks to minimize the drag through streamlining and other design factors, since drag wastes fuel, but it is physically impossible to elimnate it.

Do planes use drag?
Drag is typically minimised where possible, as it has no purpose in making flight simpler, better or more efficient.

Why did the Wright brothers achieve in flight?
I can tell you HOW: they used the forces of flight; lift, thrust, drag, and gravity That's pretty much WHY they achieved flight
What is the relationship of lift drag thrust and weight when the airplane is in straight-and-level flight?
Lift equals weight and thrust equals drag.
