Hydrodynamic drag
In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces acting opposite to the relative motion of any substance moving in a fluid. This can exist between two fluid layers(or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which is nearly independent of velocity, drag forces depend on velocity.
Drag forces always decrease fluid velocity relative to the solid object in the fluid's path.
