Question

do fluids exert friction?justify with an example

Answer 1

YES FLUIDS EXERT PRESSURE ON BODY MOVING THROUGH THEM.THAT IS THE REASON WHY THE SHIPS ,BOATS WHICH TRAVEL THROUGH SEAS AND OCEAN HAVE A SPECIAL STREMLINE SHAPE AS SHOWN IN THE FOLLOWING DIAGRAM.

FISHES ARE ALSO OF STREAMLINE SHAPE.

HOPE IT HELPS :)

Answer 2

Fluid friction is the force that resists motion either within the fluid itself or of another medium moving through the fluid. There is internal friction, which is a result of the interactions between molecules of the fluid, and there is external friction, which refers to how a fluid interacts with other matter.

Fluids are liquids and gases

Eg: When a aeroplane flies the friction of air resists its motion.
