Question

Explain why objects moving in fluids must have special shapes.​

Answer 1

Answer:

Objects in fluid face a friction of the liquid that oposses their motion .So objects in fluid must have special shape..

❥ 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.
