===Meaning===
'''Drag''' is the [[force]] of fluid resistance on an [[object]] moving through the [[fluid]].
===About Drag Force===
*'''Drag''' is also known as '''[[Air Resistance|air resistance]]''' or '''fluid resistance'''.
*'''Drag''' opposes the motion of the [[object]] and acts in the direction opposite to the [[velocity]].
*'''Drag''' depends on the [[velocity]] of the [[object]], the [[viscosity]] of the [[fluid]], and the shape and [[Surface Area|surface area]] of the [[object]].
