1. What is Buoyant Force?

Buoyant Force is the upward force exerted by any fluid upon a body placed in it. This force is equal to the weight of the fluid displaced by the object, according to Archimedes' principle.

2. How Does the Calculator Work?

The calculator uses the Buoyant Force formula:

Where:

• \( F_B \) — Buoyant Force (Newtons)
• \( V \) — Volume of Submerged part of Object (m³)
• \( \rho \) — Mass Density of the fluid (kg/m³)
• \( g \) — Gravitational acceleration (9.80665 m/s²)

Explanation: The buoyant force depends on the volume of fluid displaced and the density of the fluid, multiplied by gravitational acceleration.

3. Importance of Buoyant Force Calculation

Details: Calculating buoyant force is essential for designing ships, submarines, flotation devices, and understanding why objects float or sink in different fluids.

4. Using the Calculator

Tips: Enter the volume of the submerged part of the object in cubic meters and the mass density of the fluid in kg/m³. Both 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: Does buoyant force depend on the object's material?
A: No, buoyant force depends only on the volume of fluid displaced and the fluid's density, not on the material of the submerged object.

Q3: What happens if buoyant force equals weight?
A: When buoyant force equals the object's weight, the object will float neutrally, neither sinking nor rising.

Q4: How does saltwater affect buoyancy?
A: Saltwater has higher density than freshwater, so objects float higher in saltwater due to increased buoyant force.

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