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 is the relationship between buoyant force and gravity?
buoyant force is always or equal to the force exerted by gravity. that's why an object floats.
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 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?
Buoyant force is directly proportional to the density of the liquid. as the density of the liquid increases, the Buoyant force increases.
What happens if the buoyant force decreases?
As buoyant force decreases then the body starts sinking down.
What are the factors of buoyant force?
The buoyant force depends on the volume of liquid displaced and the density of the liquid.
Which term describes the upward push of a fluid on an object in the fluid?
the 'buoyant' force
What is the relationship between density of a liquid and the buoyant force exerted on the mass?
buoyant force = density of the liquid*Volume*gravity. so the buoyant force is directly proportional to the density of a liquid.
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.
What is the effect of buoyant force on the weight of a body which is emerged in a liquid?
Buoyant force reduces the weight of the body
What are the 2 factors of buoyant force?
The buoyant force depends on the volume of liquid displaced and the density of the liquid.
