how does an object's density affect the buoyant force acting on it?

Since g and the weight of the object Wobject are fixed, an increase in density means a decrease in the submerged volume, for the equation to hold. For a floating object, the buoyancy force is equal to the gravity force on the object. Hence, the buoyancy force doesn't change with a denser fluid.

If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink. ... The buoyant force is always present in a fluid, whether an object floats, sinks or remains suspended.

But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the object's weight.

An immersed object is pushed up by a force equal to the weight of the fluid it displaces. This force is known as the buoyant force. ... The buoyant force is the reason why ships float on the water and not sink to the bottom and why balloons float in the air. Friction is a force that opposes motion.

As water warms, it expands, decreasing density. As salt concentration rises, density increases, because the salt molecules can occupy spaces between the water molecules. Denser water sinks beneath water that is less dense. ... You can see for yourself if water can float on water.

The buoyant force on a submerged object is equal to the weight of the fluid displaced. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by measuring its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).

What happens to the buoyant force on an object as it is lowered into the water? It increases because more water is displaced. ... When the buoyant force on an object is greater than it's weight, the object__________. Floats or rises in the fluid.

Mathematically, the buoyant force on a floating (or submerged) object is , where is the density of the fluid, is the submerged volume of the object, and is the acceleration due to gravity.

In general terms, this buoyancy force can be calculated with the equation Fb = Vs × D × g, where Fb is the buoyancy force that is acting on the object, Vs is the submerged volume of the object, D is the density of the fluid the object is submerged in, and g is the force of gravity.

Archimedes' Principle states that the force exerted on an object in a fluid is equal to the weight of fluid displaced (moved out of the way) by the object. ... So if the force exerted downward on the object by gravity is less than the buoyant force, the object will float.

Salinity, temperature and depth all affect the density of seawater. Density is a measure of how tightly a certain amount of matter is packed into a given volume. The more the stuff is packed in, the higher the density. Density can be calculated by dividing an object's mass by its volume.

so as more and more volume of solid object is immersed in a liquid more is the weight of fluid displaced hence greater is the buoyant force. buoyant force becomes maximum when the whole solid object is immersed in the fluid.

If the buoyant force equals the object's weight, the object will remain suspended at that depth. The buoyant force is always present in a fluid, whether an object floats, sinks or remains suspended. The buoyant force is a result of pressure exerted by the fluid.

The density of water increases with a reduction in temperature down to 4 C. ... You are correct to state that an object is more buoyant in cold than warm water, but not your reasoning. The Plimsole lines on ships recognise the effect of temperature (and salt concentration in sea water) on the water density.

Yes, buoyant force is a conservative force. ... Conservative force-- It is a type of force acting on a body when the work done by or against the given force on the given body which depends only upon the initial and final positions of the body and is independent of the path followed to change it's position.

buoyant force: An upward force exerted by a fluid that opposes the weight of an immersed object. Archimedes principle: The buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.

The buoyant force, which always opposes gravity, is nevertheless caused by gravity. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy.
