Question

explain why objects moving in fluids must have special shapes? 5 points pls
​

Answer 1

Answer:

FLUID ARE SUBSTANCES THAT CAN FLOW OR IN OTHER WORDS A  SUBSTANCE THAT ARE NOT RIGID AND CAN BE COMPRESSED AND HAVE THE ABILITY TO FLOW ARE KNOWN AS FLUIDS. EXAMPLE: A GAS LIKE OXYGEN, HELIUM, HYDROGEN, ETC. AND LIQUIDS LIKE WATER, MERCURY, ETC. ALL LIQUIDS AND GASES ARE KNOWN AS FLUIDS.

Moving objects in fluid must have special shapes because the drag force or the friction force depends of the shape of the object. Special shapes are designed to minimize the opposing frictional force.

Explanation:

Answer 2

Here is your answer

The fluid is the name given to a substance which begins to flow when an external force is applied to it. 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.
