Question

explain why objects should have streamlined shapes while moving in fluids​

Answer 1

Answer:

Answer: Objects moving in fluids face the friction of the fluid that opposes their motion. So objects moving in fluids must have unique shapes called streamlined shapes to reduce the fluid friction. ... Therefore, special shapes are designed to minimize the opposing frictional force.

Answer 2

Objects travelling through fluids encounter friction from the fluid, which slows them down.

Explanation:

• To reduce fluid friction, objects moving in fluids must have special shapes called streamlined shapes.
• A substance that begins to flow when an external force is applied is called a fluid.
• When moving in a fluid, items must have a streamlined shape that resists the motion of other objects in the liquid by lowering the current.
• Because the drag force or friction force is dependent on the geometry of moving objects in fluid, they must have particular shapes. As a result, unique forms are created to reduce the opposing frictional force.
