### In what direction does a solid liquid exert force?

if you are asking in which direction does a liquid exert pressure on the object? then, liquid exert force in the upward direction which is called buoyancy. Brief description: when a body is partially or wholly immersed, it displaces the fluid. the displaced fluid had tendency to regain it's original position position. due to this, an upward force is exerted on the body by the displaced fluid. this upward force actiong on the the body…

### What is the relationships between force and pressure?

Archimedes a Greek mathematician who lived in third century, dicovered how to determine buoyant force. Archimedes' principle states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces. Buoyant force is the upward force that keeps an object immersed in or floating on a liquid.

### What is the name of the upward force from the water?

The upward force on objects in a fluid is called buoyant force, or buoyancy. Buoyancy is directly related to the mass of liquid displaced by a certain object. Therefore: Fbuoyancy = ρVg where ρ is the density of the fluid, V is the volume of the displaced fluid, and g is the acceleration due to gravity. For an object to stay afloat, the buoyant force it experiences must be greater than its weight, which is…

### How buoyant is a 55 gallon plastic drum?

Buoyancy depends on the density of the gas or liquid in which an object is submersed and the volume of the object, because the upward force is equal to the weight of the gas or liquid that the object disperses. If you disregard the volume of the container itself, the upward force on such a container completely submerged in pure water would be the weight of 55 gallons of water, which is about 459 pounds.

### Describe the force acting on a floating object?

When an object is floating on a liquid, there are two forces on it: -- the force of gravity (its weight), directed downward -- the buoyant force due to displacement of liquid, directed upward The magnitudes of the two forces are equal, their directions are opposite. Their sum is zero, the net force on the object is zero, and its vertical velocity and acceleration are both zero.

### How big is the upward force compared to the downward force?

It depends entirely on the situation. If the object is resting, the upward and downward forces must be equal. On a planet, like Earth, this would make the normal force (upward) and gravitational force (downward) the same quantity. In outer space, it would simply be inertia. If the object is falling, the upward force is less than the downward force. If the object is rising, the upward force is greater than the downward force.

### What is the upward force acting on an object in fluid?

The upward force is what's called the "buoyant force". It's exactly the weight of the fluid that would be in the space occupied by the object if the object were not there. What is the object doing ? Is it sinking ? Then the buoyant force is less than the weight of the object. (A rock.) Is it rising ? Then the buoyant force is greater than the weight of the object. (A basketball forced…

### Is it easier to lift a rock in water rather than lifting a rock in air?

An object submerged in a liquid or gas has an upward force, called buoyancy, acting on it that is equal to the weight of the liquid or gas displaced by the object. For example, pure water weighs about 62.4 pounds per cubic foot. Therefore, an object with a volume of 1 cubic foot that is completely submerged in pure water has an upward force of 62.4 pounds acting on it, making it feel 62.4 pounds…

### Tell a little about buoyancy?

Buoyancy is the upward force on an object produced by surrounding liquids or gas in which it's immersed due to pressure difference of the fluid between the top and bottom of the object. (ability of an object to float in a liquid) (upward force that keeps an object afloat) For an object to float it needs to have a lesser density then water If an object weighs more than it's buoyancy it sinks, if it…

### How do you derived formula of buoyant force?

well it's easy..:D we consider a cylindrical portion of a liquid and find that on an average the object(water itself) remains stationary. This gives us an idea that the upward force(buoyant force) equals the gravitational force. Therefore the buoyant force in this case is the "mg" itself but in fluids we talk in terms of the volume and density so it is V(rho)g. Plus this buoyant force in any case is independent of the object…
