Why is swimming underwater faster?
Swimming underwater is generally faster than swimming on the surface because of the following reasons:
- Reduced drag: Water is denser than air, so there is more resistance when swimming on the surface. When you swim underwater, you are surrounded by water, which reduces the drag and allows you to move through the water more quickly.
- Streamlined body position: When you swim underwater, you can keep your body in a more streamlined position, which further reduces drag. This is because you don't have to worry about keeping your head above water or breathing.
- Use of fins: Swimmers often use fins when swimming underwater, which can help to propel them through the water more quickly. Fins increase the surface area of the feet, which creates more thrust and allows swimmers to move faster.
In addition to these factors, swimming underwater can also be faster because it allows swimmers to take advantage of the Bernoulli effect. The Bernoulli effect states that as the speed of a fluid increases, its pressure decreases. This means that the pressure of the water around a swimmer's body is lower when they are swimming faster. This lower pressure creates a force that helps to propel the swimmer forward.
