Buoyant Force Formula:
| From: | To: |
Buoyant force is the upward force exerted by a fluid on an object immersed in it. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the object.
The calculator uses the buoyant force formula:
Where:
Explanation: The formula calculates the upward force experienced by an object submerged in a fluid, which depends on the fluid's density, the volume of fluid displaced, and gravitational acceleration.
Details: Understanding buoyant force is crucial for designing ships, submarines, and other marine vessels. It's also fundamental in explaining why objects float or sink and is essential in fluid mechanics and hydrodynamics.
Tips: Enter the fluid density in kg/m³, the volume of fluid displaced 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 density affect buoyancy?
A: Objects with density less than the fluid will float, while objects with greater density will sink. The buoyant force increases with fluid density.
Q3: Does shape affect buoyant force?
A: No, the buoyant force depends only on the volume of fluid displaced, not on the shape of the object.
Q4: What's the difference between buoyant force and weight?
A: Weight is the downward force due to gravity, while buoyant force is the upward force exerted by a fluid. An object floats when buoyant force equals its weight.
Q5: How does buoyancy work in different gravities?
A: Buoyant force is proportional to gravity, so on planets with different gravitational acceleration, the buoyant force would be different for the same fluid and displacement volume.
