Drag (physics)
In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces which act on a solid object in the direction of the relative fluid flow velocity. 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.

Famous quotes containing the word drag:
“Error is acceptable as long as we are young; but one must not drag it along into old age.”
