An object has to push the water out of the way (or in other words, displace water) in order to become submerged; the weight of that displaced water creates an opposing force called buoyancy, which pushes the object upward, out of the water.

When an object is submerged will it weigh less or have less mass?

Objects under water seem to weigh less but they have the same mass as they would out of water.


How much would less would you weigh in water Example If you weighed 200 on land how much would you weigh in water?

you would weigh 200 lbs. in water as you would on land. Your body just moved the water out of the way, which explains displacement. Buoyancy is what makes you seem lighter though. Because you weigh more than the water that you displaced and because the the water that you moved has a weight too, your body would be forced up after moving the water out of the way. So it's not that you weigh less in the water if someone picks you up, they just have more help when lifting you.


Why do you seem to weigh more in in than water?

The density of the human body is greater than that of water. This means that when you step into water, the water you displace has a weight equal to your weight. If you weigh more than the weight of the water that you displace, you will sink.


Why do things seem louder at night?

Things may seem louder at night because there is less ambient noise to mask the sounds, making them more noticeable and prominent.


Which planet would you weigh less that you do on earth Saturn Venus mars or Jupiter?

This question is harder than it might seem. The answer is: You would weigh less on both Venus and Mars. You would weigh more on Jupiter. As regards Saturn, you could weigh more or less depending where on the planet you were. For example, at Saturn's equator the effect of the planet's rotation would be enough to reduce your effective weight to less than your Earth weight.


What planets would a person weigh less than on earth?

You would seem to weigh less on Mars or on Venus than you do here on Earth, although the environment of Venus would be intolerable because of the high temperature and extreme pressures. On Mercury you would weigh much less, but the heat there is intense.


Why do muscles weigh more than fat?

Fat has less density than muscles, so fat will seem to weigh less than muscle. However, muscle is far better for the body than fat. Soit is always worth it to strength train and build up muscle.


Why do you seem to weigh more in air than you in water?

There is a buoyant force in water that largely counteracts gravity. Since the human body is about the same density as water, buoyancy just about completely cancels out the force you feel from gravity, effectively rendering you almost weightless. Since air is so much less dense than water the buoyant force you experience is negligible.


Why are things louder at night?

Things may seem louder at night because there is less ambient noise to compete with, making sounds more noticeable and prominent.


Why do you seem to weigh more in air than you do on water?

When you weigh yourself in water, some of your body's weight is supported by the buoyant force of the water, making you feel lighter. In air, there is no buoyant force to counteract your weight, so you feel heavier. This difference in perceived weight is due to the density and buoyancy of the medium in which you are weighing yourself.

Why does the weight of an object change in water?

because water weighs more than air, and there for, the weight difference between the water + object is less, making it seem as if the object has a smaller mass. Eg. Air = 0 (because we cant weigh it, so we set it as neutral) Water = 25 Object = 100 Object out of water = 100 Object in water = 75. Making it seem lighter
