Question

Give reason

Objects that move in water are given a streamlined shape....​

Answer 1

Explanation:

Moving objects in fluids have streamline shapes, because , When a body moves through a fluid, it experiences an opposing force which tries to oppose its motion through the fluid. ... By giving objects a special shape, that is streamlined shape, the force of friction acting on it can be minimised.

When a body moves through a fluid, it experiences an opposing force which tries to oppose its motion through the fluid. The opposing force is known as drag force. This frictional force depends on the shape of the body. By giving objects a special shape, the force of friction acting on it can be minimised. Hence, it becomes easier for the body to move through the fluid.

hope it helps u friend......

Answer 2

$\huge \sf{ \underline{Answer :-}}$

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.

• The fluid is the name given to a substance that begins to flow when an external force is applied.
• When objects move in a fluid, they must have a streamlined shape that will resist the motion of objects in the liquid by reducing the current.
• Moving objects in fluid must have special shapes because the drag force or the friction force depends on the object’s shape. Therefore, special shapes are designed to minimize the opposing frictional force.
