1. What is Buoyant Force?

Definition: Buoyant force is the upward force exerted by a fluid on an immersed object, equal to the weight of the fluid displaced by the object.

Purpose: This calculator helps determine the buoyant force acting on an object submerged in a fluid, which is essential for understanding floating and sinking behavior.

2. How Does the Calculator Work?

The calculator uses Archimedes' principle formula:

Where:

• \( F_b \) — Buoyant force (Newtons, N)
• \( \rho \) — Fluid density (kg/m³)
• \( V \) — Volume of fluid displaced (m³)
• \( g \) — Acceleration due to gravity (m/s², default 9.81)

Explanation: The buoyant force is calculated by multiplying the fluid density by the displaced volume and gravitational acceleration.

3. Importance of Buoyant Force Calculation

Details: Understanding buoyant force is crucial for designing ships, submarines, flotation devices, and understanding natural phenomena like iceberg floating.

4. Using the Calculator

Tips: Enter the fluid density (e.g., 1000 kg/m³ for water), the volume of fluid displaced by the object, and gravitational acceleration (default 9.81 m/s² on Earth).

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density of water?
A: Fresh water has a density of about 1000 kg/m³, while seawater is about 1025 kg/m³.

Q2: How do I find the displaced volume?
A: For fully submerged objects, it's the object's total volume. For floating objects, it's the volume of the part below the fluid surface.

Q3: Why is gravity important in the calculation?
A: The buoyant force depends on the weight of displaced fluid, which is affected by gravity. Use 9.81 m/s² for Earth, or adjust for other planets.

Q4: Does object density affect buoyant force?
A: No, buoyant force only depends on fluid properties and displaced volume. However, object density determines if it floats or sinks.

Q5: How does temperature affect the calculation?
A: Fluid density changes with temperature, so use the appropriate density value for the fluid's current temperature.
