Question

What is fluid friction

Answer 1

The force that resists the movement of a solid through a fluid

Answer 2

$\huge{\bf{\green{Fluid\: Friction}}}$

$<b>The common name of gases and liquids isd fluids. Fluids exert force of friction on objects in motion through them. Fluids such as air and water exert friction on objects moving through them. The frictional force on an object in a fluid depends on the nature of the fluid,/the shape of the object and the speed of the object with respect to the fluid. </b>$

$<b>Friction in a fluid is minimum for a streamlined shape, which is narrow in the front and at the back. Nature has given birds and fishes streamlined bodies. The scientists got hint from the nature. They made the bodies of aeroplanes, ships and all other vehicles in a streamlined shape to reduce friction with air or water.</b>$
