how can we reduce fluid friction without changing speed of the object and nature of fluid??
Answers
Answer:
The fluid friction or drag can be reduced are minimised by giving special shape called streamlined shape to the objects which Move through fluids like air or water .
Explanation:
Air is very light and thin, yet it exerts frictional force on objects moving through it.When an object moves through the air ,it pushes the air out of the way and air pushes back on the object. This push of air on the moving object creates fiction which tends to slow down the moving object.Air exerts frictional force on cars, buses ,aeroplanes ,rockets and birds moving through it. Water exerts force of friction on object which move through them and opposite their motion.When an object moves through water, it pushes the water out of the way and the water pushes back on the object.This push of water on the moving object creates fiction which tends to slow down the moving object.Water exerts frictional force on objects like boats, speed boats ,ships ,submarines and fishes which Move through it.
