what is the buoyant force that acts on a submerged object equal to?
232989
The buoyant force is equal to the weight of the water displaced. Distinguish between an immersed and a submerged body. An immersed body is partially or completely surrounded by water, whereas a submerged body is completely surrounded by fluid. What is the mass of 1 L of water?

Objects of equal volumes, regardless of their masses, feel equal buoyant forces when submerged in the same type of fluid. If an object is submerged, it displaces its total volume of fluid. The buoyant force on each object is the same because of identical pressure environments and equal water displacement.

Buoyant force occurs because the fluid below an object exerts greater pressure on the object than the fluid above it. If an object's weight is less than the buoyant force acting on it, then the object floats. ... Therefore, density of an object also affects whether it sinks or floats.

The reaction force acted by the water upwards is called buoyancy force which is more than your weight. Due to this, you are not in equilibrium and buoyancy force dominating your weight lifts you upwards towards the surface of water. That makes you feel weightless.

The buoyant force, which always opposes gravity, is nevertheless caused by gravity. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy.

If the center of gravity of the object is below the center of buoyancy, the floating object is stable—a push from equilibrium produces a pair of forces (called a torque couple) that act to restore the object's original orientation.

The buoyant force on a submerged object depends upon the weight of the fluid displaced by the object. There is a condition in which the buoyant force of an object does equal the weight of the object. ... The buoyant force on a submerged object depends upon the volume of the object.

If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink. ... The buoyant force is always present in a fluid, whether an object floats, sinks or remains suspended.

If the buoyant force is greater than the force of gravity, then the object will keep going up! ... However, if the buoyant force is greater than gravity, the object (example would be a balloon) it will keep going up until it is disturbed or can't any further!

Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/) or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.

An object floats when the weight force on the object is balanced by the upward push of the water on the object. The upwards push of the water increases with the volume of the object that is under water; it is not affected by the depth of the water or the amount of water.

The reason there's a buoyant force is because of the rather unavoidable fact that the bottom (i.e. more submerged part) of an object is always deeper in a fluid than the top of the object. This means the upward force from water has to be greater than the downward force from water.

Archimedes principle: The buoyant force on the ship (a) is equal to the weight of the water displaced by the ship—shown as the dashed region in (b). The reasoning behind the Archimedes principle is that the buoyancy force on an object depends on the pressure exerted by the fluid on its submerged surface.

Buoyancy is the ability or tendency to float in water, air or another fluid. Objects float when they are less dense than water, and objects sink when they are more dense than water. Density is how tightly packed the mass is in an object - it is the number of kilograms that each meter cubed of the material weighs.

The buoyant force on a submerged object is equal to the weight of the fluid displaced. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by measuring its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).

Buoyant Force: Cause and Calculation When an object is immersed in a fluid, the upward force on the bottom of an object is greater than the downward force on the top of the object. The result is a net upward force (a buoyant force) on any object in any fluid.

For an object immersed in a fluid, there's a contact force exerted by the fluid on all surfaces of the object. Since this fluid contact force is a distributed force, it's called a pressure. ... The buoyant force on a object is proportional to the volume displaced, according to Archimedes' principle.
