Lots of other scientific factors make a big difference to how well you can move through the water. That's why surfers and "wild" outdoor swimmers tend to wear wetsuits to avoid hypothermia, the very dangerous cooling of the body's core that can kill you. The same applies to actual swimming strokes. There's no reason why the swimmers couldn't be replaced by other people and, if necessary, we could put them in heatproof suits! Swimming is superb aerobic exercise vigorous exercise that really pumps your heart and lungs and very tiring; the two things are, of course, connected. But it set me thinking about Joule's experiment and whether a pool full of people, swimming furiously, would warm the water by a noticeable amount. 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. Swimming is moving your body through water a moderately viscous fluid that's either still as in a swimming pool , turbulent as in the ocean , or somewhere in between. Even so, understanding the science of swimming and mastering how we apply it can help us poor land creatures to move as efficiently through the water as possible!
