Drag (physics)

retarding force on a body moving in a fluid

dimensionless parameter to quantify fluid resistance

aerodynamic efficiency of how far an aircraft can move forward without engine power for every meter it sinks

drag that results when an object moves through a fluid

equation for the force on a body moving in a fluid

Aircraft aerodynamic drag at transonic and supersonic speeds due to the presence of shock waves

Relationship between drag on an aircraft and other variables
