Ian remember that air is a gas and
Thorpe, one of the best swimmer of the time and one can not forget Michel
Feleps the best ever swimmer also. How do they become world’s best swimmer? No doubt!!
They did it with their best of hardwork, dedication, and strong will power. But
along with all these factors they also used science, yes science of swimming.
Swimming is one of the games which uses most the energy and all the muscles of
the body also worked in this process. So it becomes very important to store
enough energy and to make muscles strong to get the success. Science is giving
major ideas for swimming in all the aspects whether it is weight, cloths, hair
style, muscles, techniques to move etc. swimming is all about to flow without
any resistance. Basically resistance is the hindrance for any object and if you
minimize the resistance, speed or any action becomes very fast. Swimming is moving your body
through water that’s either in a swimming pool or in the ocean or somewhere in
between. If you’re swimming completely under the surface (for example, scuba
diving), you’re moving through relatively still water; between air and water, with your legs, arms,
head, and body moving from one element to the other and back again, speeding up
or slowing down as they cross the border.
can understand the science of swimming, it helps to remember that air is a gas
and is very different from water a liquid. The biggest difference is that water
is much more dense and heavy in other words,
difference between air and water makes a huge difference to how we can move on
air and land. When you walk on land, the main thing your body has to do is work
against gravity like lifting your legs, swinging your arms, and keeping you
from toppling over through constant adjustments of your balance and a little
bit of friction where your shoes meet the ground. If you move more fast
air resistance becomes a more important force than gravity; unless you’re
walking into a really strong wind, you barely notice the air while you’re
walking. When you’re in the water, gravity is much less important because
your buoyancy (tendency to float) largely cancels it out. The
main force you have to think about as a swimmer is drag—water resistance.
laws of Swimming
The first law outlines the concept of inertia.
It says that all the objects in this world resist the change in their position
until or unless an external force is applied. More mass, more inertia while
less mass less inertia. The second and third laws are 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 bigger the
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 considered, the third law is
most important. According to this law that when you apply a force to an object
and it applies an equal force to you—in the opposite
This law is often called action and reaction and it’s the easiest
way to understand for a scientific non-swimmer to think importance of the
water. You might know that if you kick backward against the
wall of a swimming pool, you shoot forward through the water.
The same applies to actual swimming strokes. If you want to swim forward through
water, you have to pull water backward with your hands. If you
want your body to stay up, floating on the surface, you need to
kick down with your legs. If you’re swimming along and you
want to stop suddenly and stand up, you can pull your hands down in front of
you and your legs will swing down behind you, so you land in an upright
position on your feet.
How to minimize drag in swimming –
Newton’s Second Law of Motion: Force
= mass x acceleration. In swimming, the
force produced by the swimmer is equal to the
mass of the swimmermultiplied
by the acceleration of the swimmer in
the water. Newton’s second law can explain why
some people swim faster
than others. So it directly indicates
that the mass of a person should be proportionate according to their height if
they want to swim faster else they won’t because newton’s second law does not
give permission to a overweight person to swim faster than a less weight one.
Less mass will result in more acceleration thus fast swimming.
