What is drag, and types of Forceses acting on aircraft

Question

Accepted Answer

Drag is the force that opposes the motion of an aircraft. Types of forces acting on aircraft include lift, weight, thrust, and drag.

Drag is caused by the friction and pressure difference between the air and the aircraft's surface
There are two types of drag: parasitic drag and induced drag
Parasitic drag is caused by the aircraft's shape and surface features, such as the fuselage and wing
Induced drag is caused by the production of lift and is greater at lower speeds
Lift is the force that opposes weight and is generated by the wings
Thrust is the force that propels the aircraft forward and is generated by the engines
