Why do you swim faster underwater?

Why is it easier to swim underwater?

Ultimately, your body is floating underwater because your body is less dense than the displaced fluid. With the amount of space your body takes up underwater, your body doesn’t have enough mass to weigh you down. This is why the upward buoyant force can win against the force of gravity.

Does underwater move faster?

Take water, for example. There are about 800 times more particles in a bottle of water than there are in the same bottle filled with air. Thus sound waves travel much faster in water than they do in air. … Our head itself is full of tissues that contain water and can transmit sound waves when we are underwater.

Is swimming underwater faster than freestyle?

Why is it harder to move underwater?

Water versus air

Artwork: Water is much more dense than air (has many more molecules per unit of volume), which is why it’s harder to swim through and why it feels cold, even when it’s the same temperature as the air above. … The main force you have to think about as a swimmer is drag—water resistance.
