The force of buoyancy is responsible for the difference in weight between an object in air and water. In water, the upward force of buoyancy counteracts some of the object's weight, making it feel lighter. This is due to the water pushing against the object with an upward force equal to the weight of the water displaced by the object.
What else can I help you with?
What is the force that causes an upward movement?
The force that causes an upward movement is typically buoyancy, which is the upward force exerted by a fluid, such as water or air, that opposes the weight of an object immersed in it. This force is a result of the pressure difference between the top and bottom of an object.
What is the difference of an object weight in air and in water?
The difference in an object's weight in air and in water is due to the buoyant force acting on the object in water. In water, the object displaces an amount of water equal to its volume, resulting in an upward buoyant force that partially counteracts the object's weight. This buoyant force reduces the object's effective weight in water compared to in air.
What is the force that causes a marble to sink in water?
Gravity Gravity Density of the marble stone being greater than water causes it to sink by gravitational force.
Explain how the buoyant force acting on an object placed in water can be measured?
The buoyant force acting on an object placed in water can be measured by finding the difference between the weight of the object in air and the apparent weight of the object when submerged in water. This difference is equal to the buoyant force acting on the object, which is also equivalent to the weight of the water displaced by the object. By measuring these weights, one can determine the buoyant force acting on the object.
What is the weight difference of water at 3000 feet altitude?
The weight difference of water at 3000 feet altitude is approximately 0.5% less compared to sea level. This difference is due to the reduced gravitational force experienced at higher altitudes, resulting in a slight decrease in weight.

What is the relationship between buoyant force and weight in air when submerged in water?
There's no relationship between the weight of an object in air and the buoyantforce on it when it's in water.The buoyant force is equal to the weight of the water the object displaces,which depends directly on its volume.Two objects that have identical weight in air will experience radically differentbuoyant forces in water if their volumes are different.
What is The force which acts on all bodies in water causing them to appear to have less weight is called?
The force which acts on all bodies in water causing them to appear to have less weight is called buoyant force. This force is the result of the pressure difference between the top and bottom of the submerged object, pushing it upwards.
How do you calculate the weight of an object under water?
To calculate the weight of an object under water, you can use the equation: Weight (in water) = Weight (in air) - Buoyant force. The buoyant force is equal to the weight of the water displaced by the object. By subtracting the buoyant force from the weight in air, you can find the weight of the object in water.
What is the force of gravity acting on the block (the weight) in water?
The force of gravity on a block is the same, whether it is in air or in the water. The apparent weight (the force you need to keep it from falling) is less in water, due to the buoyancy force, which counteracts the weight.
A rock suspended by a weighing scale weighs 5 N out of water and 3 N when submerged in water What is the buoyant force on the rock?
The buoyant force is equal to the weight of the fluid displaced. In this case, there are 2 Newtons of force, leading to the buoyant force equaling 2 Newtons.
Why is there a difference between the weight of an object in air and its weight in water?
weight of object in water = (Mass of object) time acceleration of gravity - Mass of an equal volume of water times acceleration of gravity. note weight of object in water can be a negative value.
Why do things sink in water?
Objects sink in water due to the force of gravity pulling them down, which is greater than the buoyant force pushing them up. This causes the object to displace water equal to its weight, making it sink.
