When an object is submerged it experiences a upward force called buoyancy. The buoyancy force is equal to the weight of the water the object displaces. So, if a 10-pound object displaces an amount of water that weighs two pounds (about a quart's worth), the apparent weight of the object under water is eight pounds.

Objects appear to weigh less in water because water will push against the object. The object will have a downward force (gravity) pulling it that makes it seem like it is heavy but in water the water will oppose the gravity so the object seems lighter.

Because an object immersed in a fluid is buoyed up by a force equal to the

weight of the displaced fluid.

Since the buoyant force is directed upward, it acts in the direction opposite

to the force of gravity., and appears to decrease the object's weight.

it doesn't weigh any less. it has bouyancy, which means it floats.

The force of Buoyancy in water subtracts from the weight of the object in air.

What makes an object seem to weight less when you hold it in a pool of water?

This phenomenon is called buoyancy and is caused by the object displacing water equal to its volume. If the weight of the object is less than the weight of this displaced water, then the object has positive buoyancy and will float. If the weight of the object is exactly equal to the weight of this displaced water, then the object has neutral buoyancy and thus be weightless. If the weight of the object is greater than the weight of this displaced water, then the object has negative buoyancy and will sink but it still weighs less than it did out of the water.Just remember buoyancy only affects the weight of the object, it has no effect on the mass of the object which remains constant in or out of water.


How do you explain the weight of a ship and how it float on water?

An object will float on water if it has less density than the water.


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


Why will an object sink if it's more dense than water?

The basis of foating or sinking is that an object sinks into water until it displaces a mass of water equal to the objects weight. Fot onjects with a density of less than water this occurs while some of the object is still above the water. For objects denser than water even when the object is completely under the water it has not displaces a mass of water equal to the obects weight - so the object continues to sink.


If an object floats the volume of displaced water is equal to the volume of what?

Look at the LAST WORD of the question, they switch it sometimes if it is: Underwater than it is TRUE, If it's Surface of the water than it is FALSE ~

Is it true that when the weight of an object is less than the density of water that object the object will float?

The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.


Why things sink into water any why not?

An object will sink if it has a greater density than water. In this case, the weight of the water displaced by the object is less than the weight of the object.


Why the weight of object in water is less than in air?

The force of Buoyancy in water subtracts from the weight of the object in air.

What happends if the weight of an object is greather than the weight of the water?

I assume you mean "What happens if the weight of an object is greater than the weight of the water it displaces." If so, the answer is simple, it sinks. If an objects weighs less than the weight of the water it displaces, it floats.


What is Archimedes princible?

Archimedes principle states that : The force of buoyancy is equal to the weight of the displaced water. If the weight of the water displaced is less than the weight of the object , the object will sink. Otherwise the object will float , with the weight of the water displace equal to the weight of the object.

Would an object of 3.7 cm float why or why not?

Floats when it displaces its weight of water; sinks when it's displaced water weighs less than the object. Huh?


Is an object neutrally buoyant when it displaces an amount of water less than its own weight?

No, it sinks


Why is the weight of an object is less at the equator than at the poles?

The weight of an object is slightly less at the equator than at the poles because of the earth's tilt on its axis.


Why do some solids sink and some solids float?

Anything heavier than water sinks; anything lighter than water floats. Or, another way to say it: anything with a higher density than water (water weighs about a gram per cubic centimeter), or a higher specific gravity than water, sinks. If the object weighs less than the weight of water that it displaces, then it floats.


What happens when the water around objects have a force greater than the object's weight?

The water around floating object's is a measure of that object's "Displacement". For the object to float the weight of displacement must equal the object's weight. If the water around an object is of a greater weight than an object's displacement, then the object will sink.
