Question

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

Answer 1

if any object is moving in a fluid it must have a special shape as because as respect to their shape or we can call it body design it will easy to it to move in a fluid

if we give a object A cut shape then it will easy to move in a water as because it will cut the water in a stream

you can take example of the ship will that ancient time

❥The fluid is the name given to a substance which begins to flow when an external force is applied to it.

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

$\large{\boxed{\mathbb{\red{Notes :}}}}$ Streamline body is a body for which the drag force on objects moving in fluids is minimum.Streamline body represents a geometry for which the friction with fluid is low. It can simply defined as the geometry of a fish.
