What happens to the body when the upthrust is less than the weight of the object'?

An object that is COMPLETELY submerged in water has its Upthrust equal its weight, but it doesn't necessarily float, an object could be at the rock-bottom of the ocean, and it would still have its upthrust equal to its weight. This is because the upthrust is equal to the weight of the fluid displaced, and so while the objects volume remains constant, and assuming the density of the fluid it displaces is constant.. The upthrust remains constant, this is unless the object compresses and has its density altered.. I know I didn't directly answer your question, but I hope this helps.. Even if a little.

What are factors affecting upthrust?
upthrust=buoyant force=weight of the body immersed in d liquid so gravity and mass is a cause of upthrust as weight of a body=mass* gravity
The upward buoyant force on a body immersed in a fluid is equal to what?
The upward buoyant force is simply equivalent to the weight of an amount of the fluid that would occupy the same space (same volume). The total upward force on the body, if freely floating, would be found by subtracting the downward force of the body's own weight. So for example, the buoyant force on a balloon filled with air submerged in water would be equal to the weight of the same-size balloon filled with water suspended in air.
How does buoyancy affect the mass of an object?
If the average density of an object is less than water (1.0 g per mL) it will float in water, and if it is more than 1.0g/mL it will sink in water. So the lower the density, the greater the buoyancy.
What do you call the measurement of the gravitational force acting on an object?
Basically it is the object's "weight". The gravitational force on an object is its Mass X Gravitational Constant. The gravitational constant is the acceleration of a free falling body towards another body, and on Earth is equal to 9.81 meters/sec2 or 32.2 feet/sec2. Thus while the MASS of an object is a constant physical property, the WEIGHT of an object depends on the local gravity field pulling on that MASS.
What scientific rule states that the buoyant force an an object is equal to the weight of the fluid displaced by the object?
Since the object is submerged, we know that the buoyant force is not sufficient to overcome the weight of the object, otherwise it would be floating rather than being submerged. Therefore, the buoyant force is equal to the weight of the displaced water, not the weight of the object itself.
What is the effect of water on object submerged in water?
It is named as buoyant force which always acts in the upward direction ie opposite to the weight of the body. So actual weight appears to be reduced. Hence apparent weight loss
What are factors affecting upthrust?
upthrust=buoyant force=weight of the body immersed in d liquid so gravity and mass is a cause of upthrust as weight of a body=mass* gravity
If a boy has a body weight of 500 N what upthrust does he need to float?
Same as his weight
What does Archimedes' principle state?
It states that when a body is partially or completely immersed in a fluid, there is an upward force called upthrust acting on the body, which is equal to the weight of the fluid displaced by the body.
What is the apparent weight for a body floating in water equal to?
if its floating, its zero : weight or force = upthrust from water note: upthrust from water = weight of water displaced
What is equal to the weight of the fluid displaced by an object?
The upthrust on a body wholly or partly immersed in a fluid is equal to the weight of the fluid displaced.One of the earliest laws of physics to be correctly stated, this is known as Archimedes' principle.
What is the difference between thrust and upthrust?
Thrust is the only perpendicular force but upthrust is the force which act on a body when is in drown vessel
How can we determine upthrust using Archimede's principle?
The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced
Depending on the concept of buoyancy how can a relatively large ship float while a small and hard brick sink?
The determination of whether an object floats or sinks depends on the overall density of that object. The large ship, due to large pockets of air in it, has a lower density than water. The small and hard brick has a higher density than water and thus sinks. This is because the upward force acting on the body when they are immersed in water (upthrust) is equal to the weight of fluid displaced. The weight W of an object of density d and volume V can be stated as: W = dVg where g is the acceleration of free fall. Upthrust is the weight of fluid displaced. So, if a body is completely immersed in a fluid of density D, upthrust U is given by: U = DVg If D > d, then U > W and therefore the body floats (upward force greater than downward force restores the position of the body to the surface so that upthrust is equal to weight) If d > D, then W > U and therefore the body sinks (downward force greater than upward force)
How is the upthrust related to volume of the body submerged in a liquid?
The upthrust is the volume, multiplied by the weight density of the liquid in which it is submerged - or the volume, times the mass density of the liquid, times the gravitational field.
Why might different fluids have different forces of buoyancy?
When a solid body is totally immersed in a fluid, the upthrust is equal to the weight of fluid displaced. This weight is the volume of the solid body times the density of the fluid. Fluids of different densities will produce different upthrusts.Note. If the body is floating on the surface of the fluid, the upthrust does not depend on the density of the fluid. The floating solid will sink into the fluid until the upthrust exactly equals its weight, then it won't sink any deeper. In flotation the buoyancy force always equals the weight of the body, whatever the fluid's density.
Why does a body loose more weight in honey than in water?
because upthrust force in case of honey is more than water.
