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:
“The moon, also, is merciless: she would drag me
Cruelly, being barren.
Her radiance scathes me. Or perhaps I have caught her.”
—Sylvia Plath (1932–1963)
