The buoyancy force on a submarine submerged in the ocean equals what?
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
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.
An upward force exerted by a fluid on a submerged object?
buoyancy
What property of an object determines the strength of buoyancy force that will be exerted on it when submerged in water?
The buoyancy force on an object submerged in water is determined by its volume. The greater the volume of the object, the greater the buoyancy force it will experience. This is because buoyancy force is equal to the weight of the water displaced by the object, and volume directly affects the amount of water displaced.
Which factor most influences buoyancy force?
The major factor that influences buoyancy force is the density of the fluid in which the object is submerged. The higher the density of the fluid, the greater the buoyancy force acting on the object. Additionally, the volume of the submerged object also plays a role in determining the buoyancy force.
What effect does buoyancy have on a submerged object?
Buoyancy causes an upward force on a submerged object, which opposes the downward force of gravity. This force enables objects to float or rise to the surface of a fluid. The magnitude of the buoyant force is equal to the weight of the fluid displaced by the object.
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.
What are positive negative and neutral buoyancies?
Positive buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is upward, so the object tries to rise.Negative buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is downward, so the object tries to sink.Neutral buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is zero. The object stays at whatever depthit is released, without rising or sinking.
Is buoyancy contact or a non contact force?
Buoyancy is a contact force that acts on an object submerged in a fluid. It arises from the pressure difference between the top and bottom of an object.
What is the upward force on an object submerged in a fluid called?
The upward force on an object submerged in a fluid is called buoyant force. This force is equal to the weight of the fluid that the object displaces, according to Archimedes' principle.
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.
