Hint: A streamlined body is a form that reduces friction drag between a fluid and an item moving through it, such as air or water. Drag is a force that slows motion down; friction drag is a type of drug. When the fluid nearest to the item adheres to its surface, it exerts a force that resists the object's motion. Many creatures, such as birds and dolphins, and equipment, like aeroplanes and submarines, have streamlined bodies to decrease friction drag while moving through air or water.
Complete answer:
A streamlined body is a form that reduces friction drag between a fluid and an item passing through it, such as air or water. Drag is a force that slows down a moving object. The bodies of planes and ships are streamlined to minimise drag. When travelling over water or air, the streamlined body encounters the least amount of resistance. It aids in the reduction of friction. Drag is a force that opposes the motion of a fluid-filled body. Aerodynamic drag occurs when a body's motion occurs in a fluid-like environment. It's called hydrodynamic drag if the fluid is water. Drag forces always act in the opposing direction of fluid flow.
Sharks and dolphins, for example, have streamlined bodies to reduce resistance when swimming in water. The same concept applies to aeroplanes! Friction drag is greater when items are flat, such as a piece of paper. Friction drag occurs when two objects rub against each other. Aeroplanes collide with air particles as they fly. This causes them to slow down. Aeroplanes are made streamlined to assist reduce drag. Air can flow swiftly around aeroplanes and join together neatly on the opposite side in this manner.
Note: A streamlined body form that provides the least amount of resistance to air and water. The surface of aeroplanes has a streamlined form, while ships on the sea have a streamlined shape to decrease fluid friction. It was created with sleek, elegant lines on the body to provide less resistance and allow people to move more freely. A streamline is a form that is broad in the centre and narrows as it approaches the perimeter.
