The density of an object is the mass of an object divided by its volume (D = m/V).
The weight of an object is its mass times the force of gravity (Wt = mg).
Since both of these formulas have "mass" in them, one can be solved in terms of mass and then substituted in the other so that a new equation that directly relates density and weight to each other is created:
Wt = mg
Wt/g = m
D = m/V
D = (Wt/g)/V
D = Wt/Vg
*Note:
Wt = weight of the object
m = mass of the object
D = density of the object
g = force of gravity
V = volume of the object

How is weight different than density?
density is weight compared to size and how much mass is in object weight is just weight.
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
What is The density of an object is?
It is the ratio of an object's weight to its volume. Alternatively it can be said, it is the weight of the object per unit of volume.
Is density a property of an object or a property of the substance the object or a property of the substance the object is made of?
Density (or more properly Relative Density) is an elemental property. An object made from one or more elements will have a density related to the density of the elements.
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)
How is the weight of an object related to its density?
They are correlated by volume weight/volume = density. For example, in a metal coin, the weight might not be much, but the volume is also very low, so it turns out that the density is high. Gases have almost no weight in a lot of volume, so their density is low.
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.
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 detirmines the weight of an object?
The weight of an object is determined by volume, density, and gravity.
How is weight different than density?
density is weight compared to size and how much mass is in object weight is just weight.
What is volume weight and density?
volume is how much space is in an object (an object with more volume would be bigger) weight is how heavy an object feels due to gravity (an object with more weight would be harder to lift) density is how much matter is in an amount of space (an object with more density would weigh as much as an object with less density but in a smaller space/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
What is The density of an object is?
It is the ratio of an object's weight to its volume. Alternatively it can be said, it is the weight of the object per unit of volume.
Does density of an object depend on the gravity of the object?
Density is not affected by gravity. Density is affected by mass and volume, such that density = mass/volume. Weight, but not mass, is affected by gravity. Weight and mass are not the same thing.
Is density a property of an object or a property of the substance the object or a property of the substance the object is made of?
Density (or more properly Relative Density) is an elemental property. An object made from one or more elements will have a density related to the density of the elements.
How are buoyancy and density related?
The more denser an object the less buoyancy.(DrStrong) They are related through Archimedes' principle,FB = ρgVwhere FB is the buoyancy force, ρ is the density of the liquid, g is gravity, V is the volume of water displaced by the object (in other words, the volume of the object that lies underneath the water surface).If FB is greater than the weight of the object, the object will float upwards. If not, the object will sink downwards.So, the denser the liquid, the GREATER the buoyancy. However, the greater the object weight, the less the buoyancy. Another way to look at it is that the object itself has a volume and density, the product of which is the weight. So if a totally submerged object has less density than the liquid, it will be buoyant. If it has greater density than the liquid, it will sink.
What is the weight of density?
density has no weight, it is a measure of how close the atoms in an object are packed. mass per unit volume.
