Question

Explain why objects moving in fluids should have streamlined shape

Answer 1

HEY MATE HERE IS YOUR ANSWER

Moving objects in fluids have streamline shapes, because , When a body moves through a fluid, it experiences an opposing force which tries to oppose its motion through the fluid. ... By giving objects a special shape, that is streamlined shape, the force of friction acting on it can be minimised.

HOPE IT HELPS YOU!

❥ 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.
