    Introduction Viscous drag is a force that opposes the motion of an object through a fluid (like a liquid or gas), due to the viscosity of the fluid. This force plays a significant role in a variety of physical systems, from the flow of blood in the body to the flight of an airplane. Basic…

    Introduction Viscosity is a measure of a fluid’s resistance to flow. It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when…
