Question

Name two objects having streamlined body to reduce friction​

Answer 1

Answer:

aeroplane and submarine have streamlined body to reduce friction

Answer 2

It occurs when the fluid closest to the object sticks to its surface, exerting a force that opposes the object's motion. Many animals, such as birds and dolphins, and many machines, such as airplanes and submarines, have streamlined bodies to reduce friction drag as they move through either air or water.

Streamlining doesn't reduce friction, it reduces drag. ... Streamlining reduces air resistance because it reduces the surface area of the moving object that is put under a large force by the air....
