Why do you move slower in water then when just walking?

Question

The title is pretty much the question ---just why can't you move as fast as you usually can in water? Please use scientifical terms--I need to understand of science class and NO I am not cheating I am just having a hard time understanding---thanks

and what happens to the gravity--why is everything less heavy in the water---is there any connection like in space? is it a similar substance or something?

Answer 1

Whenever you walk through a substance, you have to move it out of your way. It takes work to move something out of the way, and the denser the substance is, the more work it takes (this is because matter has "inertia," or a resistance to being moved).

Water is much denser than air, so it takes more work, and that slows you down.

Now, the reason things weigh less in water is because of something called "buoyancy." Whenever you immerse an object into a fluid (a liqud or a gas) on earth, the fluid pushes up on the object by a certain amount. This is because the pressure at the bottom of the fluid is a bit greater than the pressure at the top of the fluid. The difference in pressure causes a slight upward push. If the object is light enough, the upward push is enough to push the object all the way to the top (it floats). For heavier objects, they may not float, but the upward push makes them weigh less.

Answer 2

Water is heavier than air and when you are in water, say waist deep, the water is pushing against you and it slows you down. It would be the same if you were trying to walk towards a wind that was coming toward you at 75 mph. The wind would knock you down or force you to push yourself really hard against it. I know the forces of energy are involved, but I'm not sure about the gravitational pull causing any slowdown in movement.

Answer 3

rHello,, walking through anything has some resistance. Water being a lot thicker than air causes more , that's why people swim on top, to allow a lesser force to defeat you. A smaller size will allow a lesser resistance, you have to displace the matter to get through it. Some things you cannot pass through ,you must go around or destroy it. Space has very little resistance ,a smaller force will propel you, even the wind can hold you back from going forward if it is compounded with force.

Answer 4

Speak for yourself, I move quicker in water
