Question

why object moving in fluids must have special shapes.?
plzz answer me and this is a give scientific reasons ​

Answer 1

Answer:

Special shapes experience less fluid friction, therefore, can move easily through fluids. ... Keeping all these things into consideration the shape of the ship is made in such a way that it experiences less fluid friction i.e. drag.

Answer 2

Explanation:

Objects moving in fluids face the friction of the fluid that opposes their motion. So Objects moving in fluids must have unique shapes called streamlined shapes to reduce the fluid friction

Moving objects in fluid must have special shapes because the drag force or the friction force depends of the shape of the object. Special shapes are designed to minimize the opposing frictional force.
