why do body feels light during swimming?

Answer 1

We're accustomed to walking around in air. Water weighs more than air, so we feel lighter in it.

Answer 2

Great question,....

The reason we have weight is two-fold:
1. We have mass (everything does, in fact that's a definition of something existing)
2. Earth has gravity.

Weight is the force and force is mass*acceleration according to Newton, thus weight (in theory) is mass*gravity though on Earth we use the two interchangably.

Now in water there is one more force, pressure. The water wants to push your body out canceling some affect of gravity. THe down pull is the same but you are being pulled up too. The effect is called buoyancy and happens in other liquids and gases too to some extend (I believe it depends on viscousity of the liquid)
That's why you feel lighter, unfortunatly you are not really but if you want to feel good about yourself after eating 5 icecream cones, put the scale in the pool and weigh yourself... I know I do :P

Answer 3

Eureka. Your body displaces a volume of water equal to its own volume. That water weighs pretty much the same as your body.
At depth, the water will compress your body a bit, so you when you scuba dive, you have to wear a boyancy device (air vest) to keep from plummeting to the bottom.
But at the surface, you can float, because you are displacing water equal to or greater than your own weight.
Also, and perhaps more imporant, the water is supporting your body by equal pressure over most of the surface of your body. Instead of supporting your entire weight on the soles of your feet, or along one side (if you are lying down), the water cradles you all over, which means you have no sensation of pressure ... you feel light.

Answer 4

The air in the our body acts as a buoy to keep us afloat in water. And water being a substance between the body and earth it reduces the gravitational pull of earth and therefore we feel lighter.

Answer 5

Because your body is mostly made of water!

It's a bit heavier because of our bones and proteins and such, they displace water, but otherwise when we're in water, we're mostly just water in water. Now, in sea water with high salt concentration (think tropical island), your body will float beause salt water has higher density than the water in our bodies.

In freshwater the density is about the same and thus we sink slowly.

Answer 6

Because of the upthrust of water

Answer 7

a pool of water is an anti gravity realm. that's why you float on sea.

Answer 8

buoyancy. the body displaces water.

Answer 9

gravity doesn't work under water. That's why straws work.
Ps, it doesn't work on the moon either.
You're welcome!
