How streamlined body reduces friction
A: A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. Drag is a force that slows down motion; friction drag is a special kind of drag. It occurs when the fluid closest to the object sticks to its surface, exerting a force that opposes the object ...
