Physics The Science Of Swimming - 1442 Words

Physics in Swimming (The science of swimming. (n.d.). Retrieved November 4, 2015.) The definition of swimming can be defined as moving your body through the water. Also swimming is a sport or activity of propelling oneself through the water using the limbs. Some say humans have evolved from sea creatures, but looking at our bodies no one would never know. Humans are actually less well suited to moving through water. Also we humans don t float too well, can t breathe for longer beneath the surface because we breathe air, and rapidly get tired as we thrash through the waves. One big advantage humans do have is we know about sometimes about science. We have studied how forces work and how to use them to our advantage.

The main force you have to think about as a swimmer drags water resistance. We ll come to that in a moment. Another difference between water and air is that if you swim outdoors, particularly in the wint er month, the water is much more dense than air and it removes heat from your body about 25–40 times faster than air at the same temperature. Because the water of density, it takes a long time to warm up. If you love science, but swimming scares you, you ll find it very helpful as I did when I was learning to swim to think about Newton s three laws of motion. Among the most fundamental rules of physics, these three basic principles are enough to explain completely the movement of almost every single object you re ever likely to come across. Newton’s Laws of Motion corresponds with swimming. The first law outlines the concept of inertia. It says that things stay still or move steadily, unless some kind of a force is applied. The second and third laws are also of more interest. The second law explains the connection between force and acceleration. If you push or pull something, it starts moving or goes faster. The more force you apply, the more acceleration you get; the longer you apply the force, the bigger the change in momentum you can achieve. Where swimming is concerned, the third law is perhaps the most
