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.
What else can I help you with?
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
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
If you know the weight of an object that floats you know the what?
If you know the weight of an object that floats, you can determine the buoyant force acting on it, which is equal to the weight of the fluid it displaces. This information allows you to calculate the object's density, as it will be equal to the density of the fluid it displaces.
In order for an object to have neutral buoyancy what would the relationship between the density of the object and the density of the fluid have to be?
For an object to have neutral buoyancy, its density must be equal to the density of the fluid it is immersed in. This means that the weight of the fluid displaced by the object is equal to the weight of the object itself, resulting in no net force acting on the object, allowing it to remain suspended in the fluid.
Does Archimedes' principle state that the buoyant force on an object is equal to the density of the fluid it displaces?
Yes, Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid it displaces, not the density. The buoyant force is equal to the weight of the fluid displaced by the object.
Is an object's density equal to its mass divided by its length?
Not exactly. Density is weight divided by volume.
How does density tell you if an object will float pure water?
If an object has a lower density than water, it will float. If an object has a higher density than water, it will sink. This is because objects will displace an amount of water equal to their own weight, and if the weight of the water displaced is greater than the weight of the object, the object will float.
Whose principle states that buoyant force on an object is equal to the weight of the fluid displaced by the object?
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. This principle helps determine whether an object will float or sink in a fluid based on its density compared to the density of the fluid.
What will determines if an object will float or sink in a fluid?
An object will float if its density is less than the density of the fluid it is placed in. If the object's density is greater than the fluid's density, it will sink. This is based on the principle of buoyancy, where the force of buoyancy acting on an object is equal to the weight of the fluid displaced by the object.
What happens to an object that has bigger mass than volume in water?
Essentially, if its density exceeds that of water, it will sink. If its density is equal to or less than, it will float.Note : Density of water, approx 1 g / cubic centimetre.
What determines whether an object will sink or float in fluid?
density
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 determines the sinking or floating the object in water?
An object will sink in water if its density is greater than the density of water. If the density of the object is less than the density of water, it will float. This is described by Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the water displaced by the object.
