Question

How is it useful for a body to have a streamlined shape

Answer 1

Hey mate,

A special shape of the bodies which reduces the fluid friction is called as the streamlined shape. Streamlined shapes help reduce the amount of air drag when an object is moving. This allows the object to use less energy in the movement.

Examples:-

Aquatic animals like fish, crocodiles, sharks, etc.

Vehicles like cars, flights, ships etc.

Hope this answer helps you.. :-)
