It is easier to lift a heavy stone under water because the water provides buoyant force that counters the weight of the stone. This buoyant force reduces the effective weight of the stone when submerged in water, making it easier to lift. In air, there is no buoyant force to counteract the weight of the stone, so it feels heavier to lift.

It is easier to lift a rock in water because water exerts an upward buoyant force on the rock that helps counteract the force of gravity pulling it down. In air, there is less buoyant force acting on the rock, making it harder to lift.
1 answer
The buoyant force is greater on the rock in water.

Any force directed away from the center of the Earth does that.
Examples include:
-- the buoyant force on an object in water
-- the buoyant force on a helium party balloon
-- the buoyant force on a battleship
-- the lift force on the wings of an airplane in level flight
-- the tension in the stem of an apple hanging from the tree
-- the force of arm muscles when you lift a cup of coffee
-- the force of leg muscles when you climb a step.

You can lift heavy objects more easily in water than in air because water provides more buoyant force than air due to its higher density. This buoyant force counteracts the weight of the object, making it feel lighter in water.
1 answer
It is easier to lift an object underwater because the buoyant force exerted by the water helps support the weight of the object. On land, you have to lift the object against the force of gravity without any additional support.
1 answer
Two forces that can work against gravity are lift (such as in the case of a plane generating lift to counteract gravity) and buoyancy (such as in the case of a buoyant object in water being pushed upwards).

It is easier to lift an object inside water because water exerts an upward buoyant force on the object which counteracts the force of gravity pulling the object downwards. This makes the object feel lighter and easier to lift compared to in air.
1 answer
The buoyant force of air would be greatest for a hot air balloon because it relies on the principle of buoyancy to stay aloft. The heated air inside the balloon is less dense than the surrounding air, creating a greater buoyant force to lift the balloon. A bird and an airplane rely on aerodynamic lift generated by their wings to stay airborne, rather than buoyancy.

Buoyancy is controlled by changing the mass or volume of an object. By either adding or removing weight or changing the volume of the object, the buoyant force acting on it can be adjusted. This allows the object to sink, float, or remain at a specific depth in a fluid.
1 answer
Because there is more buoyant force acting in it and because there's more pressure inside the water. When you lift it into the boat it is harder because the water is pulling it down.
1 answer
Helium is less dense than air, so when filled in a balloon it creates a buoyant force that lifts the balloon. Oxygen, being denser than air, would not create enough buoyant force to lift the balloon.

Yes, there is a buoyant force acting on you when you are submerged in a fluid. However, whether you float or sink depends on the relationship between the buoyant force and your weight. If the buoyant force is greater than your weight, you will float; if it is less, you will sink.

When the mug is underwater, the buoyant force acting on it reduces the effective weight of the mug, making it feel lighter. However, when you lift the mug out of the water, the buoyant force is no longer counteracting the weight of the mug, so it feels heavier. This difference in perceived weight is due to the buoyant force exerted by the water on the object.

The weight of standard air is 1.2256 Kg/ Cubic Meter
The weight of hydrogen is 0.0857 Kg/ Cubic Meter
The weight of helium is 0.1691 Kg/ Cubic Meter
Subtracting the weight of hydrogen from air gives you the gross buoyant lift of hydrogen as 1.1399 Kg/Cubic Meter
Subtracting the weight of helium from air gives you the gross buoyant lift of helium as 1.0565 Kg/Cubic Meter
These values are variable under altitude, pressure, temperature, humidity and purity of gas.
Hope this helps you.

Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.

Inflating bags or balloons inside a sunken ship's hull creates buoyant force, which counteracts the weight of the water that the ship displaces. This buoyant force helps to lift the ship towards the surface by reducing its overall density. As more bags are inflated, the ship becomes more buoyant and rises further towards the surface.

This force is called buoyancy. It is the upward force exerted by a fluid on an object submerged in it. Buoyancy helps keep objects afloat by counteracting the force of gravity pulling the object downward.

The weight of an object immersed in a buoyant liquid does not affect the buoyant force on the object. The buoyant force is determined by the volume of the liquid displaced by the object, not by the weight of the object itself.
2 answers
The buoyant force on an object submerged in a liquid is equal to the weight of the displaced liquid. The density of the liquid affects the buoyant force as denser liquids will exert a greater buoyant force on an object compared to less dense liquids.

It is easier to lift a metal block or massive stone underwater because buoyancy helps to support some of the weight of the object. The water exerts an upward force on the object, reducing the effective weight that needs to be lifted by the person. In contrast, in air, there is no buoyant force to counteract the weight of the object, making it feel heavier to lift.
1 answer
Yes, it is easier to lift an object in water than in air due to buoyancy. The upward force exerted by water on an object is greater than the downward force of gravity acting on the object, making it feel lighter in water. This is because water has a higher density than air, resulting in more buoyant force.

A rock sinks because it is not buoyant. Buoyancy is whether or not something floats in water. There are three levels of buoyancy; buoyant, neutrally buoyant, and not buoyant. When something is buoyant, that means it has a lower density than water, causing it to float. When something is neutrally buoyant, that means it has roughly the same density as water, causing it to float half way between the bottom and the surface. Finally, when something is not buoyant (like a rock), that means that it has a higher density than water, causing it to sink to the bottom.

The noun form of the adjective buoyant is buoyancy, a concrete noun; a word for a physical property.
There is no abstract noun form of the adjective buoyant, however, the noun 'buoyancy' can be used in an abstract context, for example:
A feeling of buoyancy came over me when she started down the aisle.

the relationship between buoyant force and gravity is that both definitions have to do with floatation . gravity and buoyant both keep you your object afloat so that it does not submerge
1 answer
it can be more or less buoyant be having more or less mass.
i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.
1 answer
The buoyant force acting on an object submerged in water is equal to the weight of the water displaced by the object. The volume of water displaced is directly proportional to the buoyant force, meaning that the greater the volume of water displaced, the greater the buoyant force acting on the object.

Pressure is related to buoyant force through Archimedes' Principle, which states that the buoyant force exerted on an object immersed in a fluid is equal to the weight of the displaced fluid. The pressure exerted by a fluid on an object is a result of the buoyant force acting on that object. As the object is submerged deeper in the fluid, the pressure and buoyant force both increase.
