Drag and lift are the forces which act on a body moving through a fluid, or on a stationary object in a flowing fluid. We call these aerodynamic forces (if the fluid is a gas) or hydrodynamic forces ...

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

The force acting on a body due to the viscous resistance of the surrounding fluid is called the drag force and it acts in the direction opposite to the direction of motion. As a consequence of the ...
