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.
What else can I help you with?
In swimming what is the relationship between drag and swimming?
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.
What is the relationship between drag and velocity in a drag vs velocity graph?
In a drag vs velocity graph, the relationship between drag and velocity is that as velocity increases, drag also increases. This means that the drag force acting on an object moving through a fluid (like air or water) becomes stronger as the object moves faster.
What are the benefits of swimming with flippers for improving speed and efficiency in the water?
Swimming with flippers can improve speed and efficiency in the water by increasing propulsion and reducing drag. Flippers help swimmers move through the water more quickly and with less effort, allowing for a more efficient and effective swimming technique.
Relationship between coefficient lift and coefficient drag?
For cylinders coefficient of lift is approximately half of coefficient of drag while they are equal for Aerofoils.
WHAT IS THE body type of penguin?
all penguins have a streamlined torpedo shaped body to help reduce drag while swimming, this increases their speed
How does aircraft drag increase with speed?
Drag increases by the square of velocity increase, for example, tripling speed increases drag by a factor of nine!
Why does friction never speed up object?
You may be thinking of drag instead of friction. Friction between the floor and your foot increases your speed.
How does drag affect an aircraft's speed?
Drag is resistance. It lowers it.
How does a sandfish relate to science?
The desert-dwelling sandfish (Scincus scincus) moves within dry sand, a material that displays solid and fluidlike behavior. High-speed x-ray imaging shows that below the surface, the lizard no longer uses limbs for propulsion but generates thrust to overcome drag by propagating an undulatory traveling wave down the body. Although viscous hydrodynamics can predict swimming speed in fluids such as water, an equivalent theory for granular drag is not available. To predict sandfish swimming speed, we developed an empirical model by measuring granular drag force on a small cylinder oriented at different angles relative to the displacement direction and summing these forces over the animal movement profile. The agreement between model and experiment implies that the noninertial swimming occurs in a frictional fluid. Chelsea
Why does drag slow you down in swimming?
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.
Why is your my swimming on its side?
Swimming is mainly on your side to create less drag and allow you to move through the water faster
What sports have specially designed clothes to reduce friction?
Sports such as cycling, swimming, and speed skating have specially designed clothing to reduce friction. In cycling, sleek and form-fitting kits are used to reduce air resistance. In swimming, streamlined swimsuits made of materials like Lycra and spandex reduce drag in the water. In speed skating, skintight suits with aerodynamic features help skaters glide faster on the ice.
