Streamlined Bodies
They have streamlined bodies so that they can cut through the wind and air
So they can swim faster (;
aerodynamic or streamlined
To increase the average speed
The objects moving through fluids r, often so designed (more pointed towards front) that air flows smoothly over their surfaces, that is, every air particle passes a particular point wid d same speed nd in d same direction. dis is called streamline flow, nd dese special shaped bodies r called streamlined body.
The reason streamlined bodies can move faster in liquid and air is because they have less surface area to cause resistance. For instance, on a windy day, an open umbrella has more resistance and can get caught up in the wind but a closed one with less resistanceÊcan not.
To make them more streamlined for faster swimming.
They need bodies like this because they dive and swim in water. This form makes it easier to do that.
The bodies of planes and boats are streamlined so that they experience minimum amount of friction while moving through air and water, respectively.
yes ... its helps it to swim through water-resistance
