Question

explain why does objects moving in fluids must have special shapes?​

Answer 1

Answer:

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. ... Therefore, special shapes are designed to minimize the opposing frictional force.

Answer 2

Answer:

The objects moving in the fluids will be facing the friction which opposes the motion of the objects. Hence the objects moving in the fluids will be having different or special shapes.

Explanation:

The objects are which are moving in the fluids are having a unique shapes which are called as streamlined shapes. This will help in reducing the friction of fluids. These special shapes are designed for the minimizing of the frictional force.
