What kind of friction does a fish experience as it swims through water
_________________________
The friction a fish experience as it swims through water is drag.
Friction Drag, also known as Skin Friction Drag, is drag caused by the friction of a fluid against the surface of an object that is moving through it. It is directly proportional to the area of the surface in contact with the fluid and increases with the square of the velocity.
____________________________________
Friction Drag is created in the boundary layer due to the viscosity of the air and the resulting friction against the surface of the aircraft. The air molecules in direct contact with the aircraft surface are most affected. As the molecules flow past the surface and past each other, the viscous resistance to that flow becomes a force which retards forward motion.
