The Buoyant force depends on the equation Fb=mfg where Fb is the buoyant force, mf is the mass of the fluid (water) that is displaced by the body and g is the Earth's gravitational constant 6.673x10-11Newton Meters squared per kilograms squared (Nm2/kg2)
Submarines use buoyant forces and gravity to move up and down with in the water. When the Buoyant force is less than the Earth's gravitational pull on the submarine, it sinks, when the buoyant force is greater than the Earth's gravitational pull on the submarine, it rises. Once the submarine is already submerged, the buoyant force is constant.
Submarines adjust the Earth's gravitational pull on it by filling the space in between the inner walls and outer walls with water and/or gasses.
With out buoyant forces, the submarine would never return to the surface of the water.
What else can I help you with?
Is there a buoyant force acting on you if there is why are you not buoyant up by this force?
Yes, there is a buoyant force acting on you when you are submerged in a fluid. However, whether you float or sink depends on the relationship between the buoyant force and your weight. If the buoyant force is greater than your weight, you will float; if it is less, you will sink.
What ocars when the buoyant force is equal to the weight of an object?
When the weight and buoyant force are exactly equal, the situation is called "neutral buoyancy", and there's no force at all on the object when it's submerged. Whatever depth you place it at, it stays right there, neither rising nor sinking, because there's no upward or downward force on it. Submarines are adjusted to this state for level cruising underwater.
Is the buoyant force of a metal equal to the buoyant force of a wood that has the same mass?
Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.
What force is opposing the buoyant force?
The force opposing the buoyant force is the force of gravity. Gravity pulls objects downward, creating a force that must be overcome by the buoyant force in order for an object to float in a fluid.
What is an buoyant force?
A buoyant force equals the weight of the fluid being displaced
What is the relationship of buoyant force and density of liquid?
The buoyant force on an object submerged in a liquid is equal to the weight of the displaced liquid. The density of the liquid affects the buoyant force as denser liquids will exert a greater buoyant force on an object compared to less dense liquids.
What is the effect of buoyant force on the ability an object has to float?
The buoyant force is what causes and object to float. If the buoyant force is less than the object weight, it sinks. If the buoyant force is greater than the objects weight, it rises to the top. If it is equal, the object will float in the middle, neither rising or falling.
What is the relationship between density of a liquid and the buoyant force exerted on the mass?
The buoyant force exerted on an object immersed in a liquid is equal to the weight of the liquid displaced by the object. The buoyant force is directly proportional to the density of the liquid. Therefore, the denser the liquid, the greater the buoyant force it exerts on the object.
What are the factors of buoyant force?
The buoyant force depends on the volume of liquid displaced and the density of the liquid.
What is the force that is working against the buoyant force?
The force working against the buoyant force is gravity. Gravity pulls objects downward, while the buoyant force pushes objects upward when they are immersed in a fluid.
Is buoyant force a contact force?
The buoyant force is a contact force, exerted by contact with a liquid that displaces the liquid within a gravity field. No contact, no force.
Does the weight of an object immersed in a buoyant liquid affect the buoyant force on the object?
It is not the weight of the immersed object but the volume of the object would affect the buoyant force on the immersed object because the buoyant force is nothing but the weight of the displaced liquid whose volume is equal to that of the immersed object.
