When a submarine is underwater does the buoyant force depend on the weight of the submarine?
Yes, the buoyant force acting on a submerged submarine depends on the volume of water displaced by the submarine, not directly on its weight. According to Archimedes' principle, the buoyant force is equal to the weight of the water displaced, which is determined by the submarine's submerged volume. However, for the submarine to be neutrally buoyant and maintain a certain depth, its weight must equal the buoyant force.
How can a submarine float and which force is acting on it?
The buoyant force keeps a submarine afloat.
Do submarines have to do with buoyant force?
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.
When does a submarine have neutral buoyancy?
A submarine has neutral buoyancy when its weight is exactly equal to the buoyant force acting on it, causing it to remain suspended at a constant depth without sinking or rising. This balance between weight and buoyant force allows the submarine to move up or down in the water column as needed.
What are the forces acting on a submarine travelling at a constant depth?
When a submarine is traveling at a constant depth, the primary forces acting on it are buoyancy, gravity, drag (or hydrodynamic resistance), and thrust. The buoyant force, which acts upward, is equal to the weight of the water displaced by the submarine, while gravity pulls the submarine downward. For the submarine to maintain a constant depth, these forces must be balanced, meaning the buoyant force equals the gravitational force. Additionally, the thrust generated by the submarine's engines must counteract the drag force to maintain a steady speed.
Which has higher buoyant force submarine near the surface or near the ocean floor?
The force is the same as long as the volume submersed is the same
Will a submarine sink or float when its weight is greater than the upthrust acting on it?
When the weight of any object surrounded by fluid is greater than the buoyant force on it, it sinks. (The buoyant force is just the weight of the fluid that would be in that space if the submerged object were not there.)
What happens to the buoyant force of a submerged submarine when water is taken into its tanks and it dives?
When water is taken into the tanks of a submerged submarine, its total volume increases, displacing more water and increasing its buoyant force. This increases the upward force acting on the submarine, causing it to rise in the water or maintain a shallower depth.
Will a submarine sink or float when it's weight is equal to the upthrust acting on it?
If the weight of the submarine is equal to the upthrust acting on it, the submarine will float. This is due to Archimedes' principle, which states that an object will float when the buoyant force acting on it is equal to the gravitational force pulling it down.
How does a submarine change its buoynacy so it can float or sink?
This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.
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.
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.
