It is called viscosity. According to boundary layer theory,drag force exists due to viscosity of fluid.

Kinetic Friction (specifically, Fluid Friction). This also applies to an object moving through a gas.

Two forces are experienced when a body moves thru a fluid. The first one is perpendicular to the body, the LIFT force(or reverse of lift). The second one is the DRAG force. Normally we wish to reduce the drag as much as possible.
In an aeroplane we want small drag and big lift. In a car we want little drag and downward lift(Formula 1). In a saling boat we want maximum drag on the sails and zero drag btn the water and boat!

It's called Viscosity and acts against the motion of any solid object through the fluid as well as against motion of the fluid itself against stationary obstacles.
Have a good one

Neither, or both. Friction is resistance to both a push or a pull, so if you're pulling something, friction"pushes"; if you're pushing something, friction "pulls". do not imagine of it as a push or a pull yet a rigidity contained in the different route of the rigidity you're putting on an merchandise. study physics, and once you get to loose body diagrams you'll understand more effective.
