1. What is Buoyant Force?

Buoyant force is the upward force exerted by a fluid on an object submerged in it. It is equal to the weight of the fluid displaced by the object, as described by Archimedes' principle.

2. How Does the Calculator Work?

The calculator uses the buoyant force equation:

Where:

• \( F_b \) — Buoyant force (N)
• \( \rho \) — Fluid density (kg/m³)
• \( V \) — Displaced volume (m³)
• \( g \) — Gravity (9.81 m/s² on Earth)

Explanation: The equation calculates the upward force experienced by an object immersed in a fluid, which depends on the density of the fluid, the volume of fluid displaced, and the gravitational acceleration.

3. Importance of Buoyant Force Calculation

Details: Calculating buoyant force is essential for understanding floating and sinking behavior of objects, designing ships and submarines, and various engineering applications involving fluid mechanics.

4. Using the Calculator

Tips: Enter fluid density in kg/m³, displaced volume in m³, and gravitational acceleration in m/s². All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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.

Q3: Does shape affect buoyant force?
A: No, buoyant force depends only on the volume of fluid displaced, not on the shape of the object.

Q4: What is the standard value for gravity?
A: On Earth's surface, standard gravity is approximately 9.81 m/s², but it varies slightly with location.

Q5: Can this calculator be used for gases?
A: Yes, the same principle applies to gases, though the densities are much lower, resulting in smaller buoyant forces.
