Answer 1

Objects are given special shapes when they are moving through Fluids because:

• They experience fluid friction which acts opposite to their direction of movement

• This frictional force or opposing force is known as a drag force.

• Due to these special shapes of objects, the opposing force can be minimized and they can move easily.

• The name given to these special shapes is called a streamlined shape.
