I assume you mean when you put the object in a fluid. In this case the object sinks.

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 its floating, its zero : weight or force = upthrust from water note: upthrust from water = weight of water displaced


This is because there is no upthrust in vacuum so the gravitational force is the weight. In water, there is an upthrust which gets subtracted from the gravitational force. Therefore a body always weighs more in vacuum than in air.


Upthrust is a type of force that pushes things upwards. e.g. When an object is immersed in water the object experiences upward force from the water, which is called upthrust.OR.The upward force exerted on a body by the fluid in which it is submerged is called upthrust or buoyant force.



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.


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


When a body is completely or partially immersed in a liquid at rest, the liquid exerts thrust at every point on the body in contact with the liquid. The pressure varies with the depth of the point below the free surface of the liquid.That is the upward thrust on the lower part of the body is greater than the downward thrust on the upper part.Hence the body experiences a resultant upward thrust. This upthrust is called buoyancy. Due to this upthrust it experiences a loss of weight


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.


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.


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)


Archimedes' principle states that when a body is immersed partially or completely in a liquid, it experiences an upthrust, or buoyant force, which is equal to the weight of the amount of the object that's being submerged.


Weight is the measurement of the pull of gravity on an object or body.Mass is the amount of matter in a body or object.


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.


because upthrust force in case of honey is more than water.


Objects are normally weighed on scales. If you want to weigh an object while holding it away from your body, you can stand on the scale, holding the object away from your body, and then subtract your own weight from the total. The object has the same weight whether held close to or distant from your body.


When an object is immersed in a liquid, the liquid exerts a buoyant force on the object which is equal to the weight of the liquid displaced by the object. This statement is known as Archimedes' Principle. When a solid body is immersed wholly or partially in a liquid, then there is same apparent loss in its weight. This loss in weight is equal to the weight of the liquid displaced by the body. the bouyant force of an object equal to the weight of the fluid that the object displaced .


the weight of a body = mass X acceleration due to gravity. So weight of an object is directly proportional to the gravity.


No. The mass of any object is considered to be an intrinsic constant property, i.e. it's a characteristic of the object and it doesn't change, no matter where the object goes or what happens to it. The weight of the object may change, because that's just the force of gravity caused by whatever large body the object happens to be near, like the earth or moon.


Looking at the definition of Weight:Physics . the force that gravitation exerts upon a body, equalto the mass of the body times the local acceleration of gravity[dictionary.com]In the absence of gravity an object with mass does not have weight.


when a body is immersed in a fluid,it experiencednan upward force called upthrust or buoyant force due to the liquid.It is this force that pushes the body up and supports it.


An object surrounded by fluid is buoyed up by a force equal to the weight of the displaced fluid. It doesn't matter whether the fluid is water, as in the case of a canoe, or air, as in the case of a blimp, or any other fluid.


The line of action of weight is outside the base of the body.


Mass is the amount of matter a body has. Gravity is a pulling force that pulls the object towards the core of the body. The weight of a body depends on the mass; gravity causes weight. Weight is a downwards force towards the core of the body that produces a gravitational field (e.g. Earth). The relation between the mass, the weight and the gravitational field strength is: W = m.g - where W is the weight of the object, m is the mass of the object and g is the gravitational field strength of the body (it is roughly about 10N/kg on Earth)


Mass: Does not change Weight: The weight will be zero, if you are not standing on a large massive body (like the moon). When in orbit you are actually in continuous freefall around the planet with a sufficient tangential velocity component. Volume: If the object is filled with gas from the earth's lower atmosphere the gas will exert this pressure on the sides of the object, prehaps causing the object to explode.
