1. What is Buoyant Force?

Buoyant force is the upward force exerted by a fluid on any object placed in it. According to Archimedes' principle, the magnitude of this 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:

Where:

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

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

3. Importance of Buoyant Force Calculation

Details: Calculating buoyant force is essential for understanding flotation, designing ships and submarines, and analyzing fluid dynamics in various engineering applications.

4. Using the Calculator

Tips: Enter fluid density in kg/m³, displaced volume in m³, and gravitational acceleration in m/s². Standard gravity is approximately 9.8 m/s² on Earth's surface.

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: Objects denser than the fluid sink, while less dense objects float. Objects with equal density remain suspended.

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

Q4: How is this different from weight?
A: Weight is the downward force due to gravity, while buoyant force is the upward force exerted by the fluid.

Q5: Can this calculator be used for gases?
A: Yes, the same formula applies to gases, though density values are much lower for gases compared to liquids.
