Well "drag" is usually used to describe something that will slow you, like a drag suit worn over a jammer or Fastskins, or simply wearing another suit. Swimming without that will not slow you at all, therefore in practice swimmers use drag to improve and go faster in meets.
For cylinders coefficient of lift is approximately half of coefficient of drag while they are equal for Aerofoils.
When you are not in a streamline position in swimming, drag can occur. This is when you body is stopping the water from freely moving past your body. You may notice when you begin to sink while you are swimming that you slow down. This is because the lower part of your body is creating drag by stopping the water from quickly passing you legs.
Swimming is mainly on your side to create less drag and allow you to move through the water faster
Yes, the preposition in the sentence is "for" as it shows the relationship between "too cold" and "swimming."
hahaha no
So that it does not cause drag and slow you down while swimming.
There is no difference between the two. It is also called profile drag.
A simple way to put it would be; - Decrease drag - Improve propulsion
viscous drag- the same as swimming or diving into a pool.
Lift is opposite of weight Thrust is opposite drag. When lift >weight plane climbs. If lift < weight you best find a place to land. If thrust> drag you accelerate. If drag>thrust you slow down. High and fast are your friends. Low and slow are out to kill you.
so you do not drag in the water... say your on a bike and the wind is pushing against you that the wind resistance in the air... while as your swimming if you r wearing a drag suit it will slow you down.... that's why swimmers where fastskins, lazers, and other tight suits.....
As with all objects in motion, there is friction. Drag is created by friction along the surface of an object, in this case its a body moving through the water. There is also places where the water will eddy or swirl around and create a pull on the object. As you move through the water your body must displace the water, move it out of the way. As it goes along the sides of the body it causes friction which slows down the progress. Due to different body shapes the drag will be different for each person. A tractor trailer may have a large wind deflector on the top of the cab to push the wind away from the trailer. This reduces drag along the trailer which helps it go faster with less energy. Its the same thing with swimming. Swimmers wear swimming caps because their hair actually slows them down due to drag.
