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.
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.
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.
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.
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.
A buoyant force equals the weight of the fluid being displaced
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.
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.
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.
The buoyant force depends on the volume of liquid displaced and the density of the liquid.
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.
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.
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.
