the physics of swimming



the physics in swimming contains three components; resistance, drag, and hydro-dynamics. Water is 1000 times more resistant than air. Swimmers need to maximize their strealine and reduce the surface area of the human body traveling through the water. 91% of a person's energy is lost through the drag force the water creates. Minimizing the surface area is achieved by tightening the body to resemble a torpedo. In order to reach a fast velocity, the swimsuit must be designed to be similar to the skin of a shark. Sharks are chosen because of their very fast velocity,even though their surface area is large. To decrease the surface area of a swimmer's head, they wear swim caps to cover any ways to slow them down.
