Question

Why object moving in fluids must have social shapes

Answer 1

Explanation:

The object moving in fluids must have social shapes,called streamlined shapes.

Streamlined shapes are given in objects because it helps in increasing speed and reducing friction.

Why objects moving in fluids must have special shapes.

❥ 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.
