Drag is a force that acts opposite to the direction of motion of an aircraft as it moves through the air. This force is caused by air resistance and friction against the aircraft's surface. Drag slows down the forward movement of the aircraft by requiring additional thrust from the engines to overcome it.
What else can I help you with?
How does the drag affect the forward motion of the airplane?
Drag is a force that acts in the opposite direction of the airplane's motion, creating resistance and slowing down the aircraft. This requires the engines to work harder to maintain forward motion, resulting in increased fuel consumption and reduced speed. Pilots and aircraft designers must account for drag to optimize performance and efficiency during flight.
What are two forces that oppose flight?
Gravity and drag are two forces that oppose flight. Gravity pulls the aircraft downward, while drag slows the aircraft's forward movement. Both forces must be overcome for an object to achieve and maintain flight.
What types of force can an airfoil exert?
An airfoil can exert lift, drag, and thrust forces. Lift force is generated perpendicular to the airflow and is essential for providing the upward force needed for an aircraft to stay aloft. Drag force acts opposite to the direction of motion and resists the aircraft's movement. Thrust force is generated by the aircraft's engines and propels the aircraft forward.
What term describes the air resistance that slow down aircraft?
The term that describes the air resistance that slows down aircraft is drag. Drag is caused by the friction between the aircraft and the air it is moving through, leading to a decrease in speed and increased fuel consumption. Pilots must account for drag in their flight planning to ensure efficient and safe flying.
What fluid force of opposes lift?
The fluid force that opposes lift is drag. Drag is the force that acts opposite to the direction of an object's motion through a fluid, such as air. It acts to slow down the object's movement, including an aircraft's forward motion.

What is drag in an aircraft?
In aircraft aerodynamics, drag is the force that opposes forward motion, caused by air resistance as the aircraft is pushed forward by it's engines.
What does drag do for an aircraft?
Drag slows down aircraft, which is why designers of aircraft that are supposed to be fast pointy and waisted, because a pointy shape has less drag, and waisted because of the area rule, which also helps an aircraft to go faster.
What are the purposes of the slats and flaps of an airplane's wings?
Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.
What is thrust for an airplane?
Thrust is the produced force of the aircraft that propels the aircraft forward in order to overcome drag. Drag is the natural force of the air that resists the motion of the aircraft.
What are the four forces acting on an airplane during flight?
Thrust - The aircraft being pulled (or pushed) forward through the air. Drag - The aerodynamic friction slowing down the aircraft's forward movement. Lift - The lifting force of the wing. Weight - The force of gravity pulling the aircraft towards the ground.

What force is created when an object moves through a fluid like aircraft moves through air?
Either drag (air resistance) slows the aircraft down, or lift (Bernoulli's principle) raises it up. When more air goes under the wing than over it, the aircraft "wants" to move up because objects favor movement into low pressure zones.
