No, it's not.
Gravity is the force of attraction between objects having mass, where the force on an object is given by the product of the gravitational acceleration and the object's mass. Gravitational acceleration has the units of length per time squared.
The density of an object or material is the mass of the object divided by its volume, e.g., water has a density of 1 g per mL. Density has the units of mass per volume.

∙ 14y agoNo,
You can have an incredibly dense object with a low mass and a object with a massive mass but low density.
Density is proportional to mass and volume. Low volume high mass = high density
high volume low mass = low density.

∙ 13y agoNo - the specific gravity is a ratio of the substance's density with the density of water for solids and liquids and with respect to air for gases. So as water has a density of 1 g/cm3, and substance X has a 1.25 g/cm3, the specific gravity would be (1.25g/cm3)/(1.00g/cm3)= 1.25. The comparison is usually done at standard temperature and pressure to eliminate density changes. Note specific gravity is unitless as the g/cm3appears in both numerator and denominator of the equation and cancels out.

∙ 12y agoNo. Its related to the denity, but you also have to consider the volume of an object. Density is a measure of how heavy something is for a given volume, usually expessed as kg per cubic metre - that's the SI form, or grams per cubic centimetre (g/cc). Density expressed as 1 kg per cubic metre is the same as saying grams per cubic centimetre. Density is mass divided by volume and is usually represented by the greek letter ρ (rho).

Is an object's density equal to its mass divided by its length?
Not exactly. Density is weight divided by volume.
If an object that floats on the surface desplaces 10 cm3 of water how much does that object weigh?
By Archimedes' Principle, a floating body displaces a volume of fluid whose weight is exactly equal to its own.This assumes that the body is in equilibrium.In order to know the weight of the body (i.e. the object) you must know the density of the fluid in which it is floating.Also, Surface Area (SA, in cm2) of object must be known.Suppose density of the fluid is rho.Thus, Having height = 10cmWobject = Volumedisplaced*Densityfluid = SA*Height*rhoSuppose it is water with rho = 1g/cm3, SA = 1cm2Wobject = 10cm*1cm2*1g/cm3 = 10g.Just make sure your units are correct.
If the density of an object is equal to the density of the fluid in which it is immersed?
If the density of an object which is equal to one(Which is also the density of the water), the object will neither sink nor float but it will be unstable, sometimes you will see the object sink then float. In other words the object is unstable in water....XD
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 does the weight of an object that floats have the same value as?
The weight of the substances are largely immaterial. What matters is the density. Assuming fresh water to have a density of 1.0 anything with a lighter density will float in it. For example, oil generally has a density of about 0.8, so it floats in water. Concrete has a density of about 2.4, so it sinks. http://physics.about.com/od/fluidmechanics/a/commondens.htm
Is an object's density equal to its mass divided by its length?
Not exactly. Density is weight divided by volume.
When the buoyant force on a submerged object is equal to the weight of the object how do the densities of the object and water compare?
Is is related through Archimedes principle, which states that the buoyancy force on an object is equal to the weight of liquid displaced by the submerged object. The weight of a volume of water is equal to the volume x density of water x the gravitational constant.FB = V ρ g
When will an object float in a liquid?
An object will float in a liquid when the density of the liquid is higher than that of the object or when equal. That is to say Upthrust= or >weight of the object
What has to happen for an object to float?
For an object to float, it must displace an amount of fluid equal to its weight. This is known as Archimedes' principle. If the weight of the object is less than the weight of the fluid it displaces, the object will float; if the object is denser than the fluid, it will sink.
Is it true that when the weight of an object is less than the density of water that object the object will float?
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
How is buoyancy figuired?
The buoyant force on an object is equal to the weight of the water displaced by the object. In essence, this equals the product of the water's density, volume of the object, and gravitational acceleration.
What is density and how is the density of a substance calculated?
Density is the weight of an object per unit of volume. For instance, the density of gold is 19 grams per cubic centimeter. To calculate the density of an object divide the weight of the object by the volume.
What is the floatation formula?
Formula for Buoyant Mass m(b) m(b) = m(object) x (1- (p(fluid)/ p(object))) m(object)= true mass of the object p(object)= average density of the object p(fluid)= average density of the surrounding fluid If the fluid density is greater than the average density of the object, the object floats. If less, the object sinks. Formula for Buoyant Force: F(buoyant) = -pVg p = density of the fluid V = volume of the object being submerged g = standard gravity on Earth (~ 9.81 N/kg) Archimedes Principle: "When a solid body is partially or completely immersed in water, the apparent loss in weight will be equal to the weight of the displaced liquid." Formula for Density of immersed object relative to the density of the fluid object is immersed in: Relative Density = Weight / (Weight - Apparent Immersed Weight)
What detirmines the weight of an object?
The weight of an object is determined by volume, density, and gravity.
