What else can I help you with?
Why do you weigh less in water?
Because sea water is more dense than regular water
Why fish weigh less in water than in air?
Fish weigh less in water because of buoyancy, which is the upward force exerted by a fluid that counteracts the weight of the object immersed in it. The water exerts an upward force on the fish that partially cancels out the downward force of gravity, making the fish weigh less in water than in air.
When does a object float or sink in water?
A steel needle will float in water as a consequence of surface tension. A boat floats in water because it displaces sufficient air to make its effective density less than that of water. Usually though, solid, spherical objects, for example, will float if they are made of materials that are less dense that water, which is to say that they have less mass per unit volume than water. In ordinary, imprecise language we say things weigh less than water.
Do objects weigh less in water or do they just appear to be weightless?
Objects weigh less in water than they do in air because of the buoyant force exerted by the water. This force counteracts the weight of the object, making it feel lighter or even weightless when submerged in water.
What would happen if you tried to find the density of an object with a density less than water?
If you try to find the density of an object with a density less than water, the object will float in water. This indicates that the object is less dense than water. To find the density of such an object, you would divide the mass of the object by its volume.
What force makes an object float on water?
An object floats on water when the buoyant force acting on the object is greater than the weight of the object. This buoyant force is exerted by the water displaced by the object, pushing it upwards. Objects that displace more water than they weigh will float, while objects that displace less water will sink.
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.
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.
Would an object weight more or less on the moon and why?
An object would weigh less on the moon compared to Earth because the moon has less gravitational pull than Earth. Weight is a measure of the gravitational force acting on an object, so with less gravitational pull on the moon, the object would weigh less.
What object is less dense than water?
A wooden block can be less dense than water.
How dense must an object be to float in the water?
An object will float in water if its density is less than the density of water, which is approximately 1000 kg/m^3. This means that the object must be less dense than water in order to float.
Why does AV gas weigh less than water?
no
