When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.

How can friction on a water slide be reduced?
When objects move through fluids, they have to overcome the friction acting on them, due to which they lose energy. So, efforts are made to minimize the friction. For this, the objects are given special shapes. As we know, birds and fishes have to move about in fluids all the time. Their bodies must have evolved to shapes which would make them lose less energy in overcoming friction. Such shapes are called streamlined shapes. This is the reason ships and aeroplanes are given a streamlined shapes so that minimum energy is lost while moving through water and air respectively.
Is it true that pictures shapes and objects can serve as hyperlinks?

Why are wheeled useful for moving heavy objects?
Less surface area contacting the ground reduces friction. Wheels are useful for moving heavy objects so you don't hurt your back.
What objects are cylinder shapes?
Cigarettes...
What are the special features of 3D shapes?
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.
What objects are octagons?
8 sided shapes
What Objects in nature that have geometric shapes?
starfish
What objects are 2d shapes in the house?
Shadows
What perceptual abilities do newborns and infants have?
Newborns can see contrasting colors, focus on objects about 8-12 inches away, and identify basic shapes. Infants can track moving objects with their eyes, recognize familiar faces and voices, and begin to understand depth perception.
An art work that has shapes but no recognizable objects?
abstract art
How the fluid friction can be minimized?
There are three main ways to reduce friction:Lubricate the surface/sSmooth the surfaceReduce the force pushing the objects togetherI don't think it's actually possible to completely stop friction
