THE FORCES EXERTED BY FLUIDS IS CALLED FLUID FRICTION.
OBJECTS MOVING IN FLUIDS MUST HAVE SPECIAL SHAPES BECAUSE TO MOVE EASILY IN FLUIDS .
EXAMPLE AIRPLANES and fish.

its so easy. fluid friction is friction like to solid bodies. in these there is different in velocity in layer of water. due to dragging force acting on the different layers. so the speed will be different in different layers
the object must have a hydrodynamic shape means which can cut the water . which cause less friction so the object can move fastly in water. if the surface is not hydrodynamic it will resisted by the water and velocity will be reduce
