Buoyancy Force Formula:
| From: | To: |
Buoyancy force is the upward force exerted by a fluid on an object immersed in it. This force opposes the weight of the object and is described by Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.
The calculator uses the buoyancy force formula:
Where:
Explanation: The formula calculates the upward force exerted on an object submerged in a fluid, which depends on the density of the fluid, the volume of fluid displaced, and the gravitational acceleration.
Details: Calculating buoyancy force is essential in various fields including naval architecture, marine engineering, fluid mechanics, and designing floating structures. It helps determine whether an object will float, sink, or remain neutrally buoyant in a fluid.
Tips: Enter fluid density in kg/m³, displaced volume in m³, and gravitational acceleration in m/s² (default is Earth's gravity: 9.81 m/s²). All values must be positive numbers.
Q1: What is Archimedes' principle?
A: Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid it displaces.
Q2: How does object density affect buoyancy?
A: If an object's density is less than the fluid's density, it will float. If greater, it will sink. If equal, it will remain neutrally buoyant.
Q3: Does shape affect buoyancy force?
A: The shape doesn't directly affect the magnitude of buoyancy force (which depends only on displaced volume), but it does affect whether and how an object floats.
Q4: How is this different from weight in fluid?
A: The apparent weight of an object in fluid is its actual weight minus the buoyant force acting on it.
Q5: Can this calculator be used for gases?
A: Yes, the same formula applies to gases, though the density values are much smaller, resulting in smaller buoyancy forces.
