Question

Explain why objects moving in Fluids should have streamlined shape.

​

Answer 1

Answer:

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.

Answer 2

Answer:

some objects in fluids have stream lined shape because the streamlined shape cuts the water currents and helps the object to move smoothly.
