What force causes a difference in weight in air and water?
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.
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 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 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.
Amount of water in an object?
The amount of water in an object can be determined by calculating the difference in weight before and after submerging the object in water. The weight difference is equal to the amount of water displaced by the object, which can then be converted to volume using the density of water (1g/cm3).
What is water buoyancY?
The difference between an object's weight, and the weight of water with the same volume as the object.

Why is there a difference between the weight of an object in the air and it's weight in water?
Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.
What is the apparent mass in water?
The apparent mass in water refers to the apparent weight of an object when immersed in water. This weight is equal to the difference between the actual weight of the object in air and the buoyant force acting on it while submerged in water.
What is the effect of water on object submerged in water?
When an object is submerged in water, it experiences buoyant force, which is an upward force exerted by water due to the pressure difference between the top and bottom of the object. This buoyant force counteracts the weight of the object, causing it to feel lighter. Additionally, water can also cause objects to experience drag force as they move through the water.
Why does bouyant force act upward on an object submerged in water?
The buoyant force acts upward on an object submerged in water because of the difference in pressure between the top and bottom of the object. The pressure at the bottom of the object is higher than at the top, resulting in a net upward force on the object. This force is equal to the weight of the water displaced by the object, pushing it upward.
What is the origin of upthrust in fluid?
Upthrust in fluid, also known as buoyant force, is caused by the pressure difference between the top and bottom of an object submerged in a fluid. This pressure difference creates a net force pushing the object upwards. It is a result of Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
How can one accurately measure buoyancy in a given object or substance?
To accurately measure buoyancy in an object or substance, you can use a scale to measure its weight in air and then in water. The difference in weight between the two measurements can help determine the buoyant force acting on the object, which is equal to the weight of the water displaced by the object. This method is known as Archimedes' principle and is commonly used to measure buoyancy.
