Physics of Swimming



blog-0189310001368848914.jpgSwimming can be used in a variety of ways. Some use it for recreation while others use it for sport and competition. Regardless of how it is used there are many forms of physics that are used.

The video below demonstrates and explains the various aspects of physics in swimming...

With this video you can see all the different aspects of physics ( acceleration momentum, force, velocity and Newtons Laws of Motion, as well as drag coefficients) that are involved in the simple act of swimming.

Acceleration is used when starting from any initial speed and increasing or decreasing speed... not just from diving as shown in the video.

Momentum is used all the time while you are swimming. When you are not trying to accelerate in any way your momentum makes it easier to stay at a constant speed.

Force can be very useful in all motions of swimming. Every movement needs a force to allow it to happen...

All of Newtons Laws of Motions also come into play. This is what makes swimming the way it is...

Drag comes into play more with competitive swimming. Drag is what holds you back as you swim. When swimming, the water must be "moved" out of the way. This is what keeps you from swimming extremely fast. The faster you swim the quicker the water must be moved and the greater the drag.
