Aircraft design reduces drag, but cannot prevent it. Aerodynamics is the study of such.
Drag slows the forward movement of aircraft.
Drag
Aerodynamics help reduce drag so the engines can produce thrust.
In general (special exceptions may apply) increase speed = increase drag.
LIFT -- force provided by the wing and in perpendicular direction to the wing. In straight and level flight the lift is exactly equal to the aircraft weight. WEIGHT -- the force pulling vertically down on the airplane due to gravity. In straight and level flight this is equal to the lift. THRUST -- the force that pulls the airplane forward, provided by the propeller or jet engine. If the airplane is flying at a constant speed in level flight, this thrust is exactly equal to the drag. DRAG -- the aerodynamic force on the airplane in the opposite direction of its travel. Drag is due to skin friction, form drag (drag around wheels, struts, etc) and induced drag (produced by the wing as a side effect of lift)

Drag slows the forward movement of aircraft.
Drag is a force that acts opposite to the direction of movement of an airplane. Drag is mainly caused by air. The other forces that act on the plane while moving in the air are thrust, lift etc..
The drag of an airplane is the air resistance caused by the plane flying through air. Similar to when you pull your hand through water and feel resistance.
Flaps would increase drag increasing your speed will increase it even more
Drag effects paper airplane just as it affects anything else that moves. It is either parasitic or induced on paper airplanes. Drag may reduce a paper airplanes speed and/or range.
