1. What is Buoyant Force?

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

2. How Does the Calculator Work?

The calculator uses the buoyant force formula:

\[ F_b = \rho \times V \times g \]

Where:

\( F_b \) — Buoyant force (Newtons)
\( \rho \) — Fluid density (kg/m³)
\( V \) — Volume of displaced fluid/object (m³)
\( g \) — Gravitational acceleration (m/s²)

Explanation: The formula calculates the upward force experienced by a fully submerged object in a fluid, which depends on the density of the fluid, the volume of the object, and the gravitational acceleration.

3. Importance of Buoyant Force Calculation

Details: Calculating buoyant force is essential for designing ships, submarines, and other marine vessels. It's also crucial in understanding floating and sinking phenomena, fluid mechanics, and various engineering applications.

4. Using the Calculator

Tips: Enter fluid density in kg/m³, volume in m³, and gravitational acceleration in m/s². Standard gravity is approximately 9.81 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: Does buoyant force depend on the object's material?
A: No, buoyant force depends only on the fluid density and the volume of the object, not on the object's material or composition.

Q3: What happens if buoyant force equals the object's weight?
A: If buoyant force equals the object's weight, the object will float and remain suspended in the fluid.

Q4: How does saltwater affect buoyant force?
A: Saltwater has higher density than freshwater, so objects experience greater buoyant force in saltwater, making them float more easily.

Q5: Can this formula be used for partially submerged objects?
A: For partially submerged objects, you need to use the volume of the submerged portion only, not the total object volume.
