1. What Is Buoyant Force?

Buoyant force is the upward force exerted by a fluid on an object immersed 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:

Where:

• \( F_b \) — Buoyant force (Newtons)
• \( \rho \) — Density of the fluid (kg/m³)
• \( V \) — Volume of fluid displaced (m³)
• \( g \) — Acceleration due to gravity (9.81 m/s²)

Explanation: The formula calculates the upward force experienced by an object submerged in a fluid, which depends on the fluid's density, the volume of fluid displaced, and 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. For water at standard conditions, use ρ = 1000 kg/m³ and g = 9.81 m/s².

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 object's shape or composition.

Q4: What is the difference between buoyant force and weight?
A: Weight is the downward force due to gravity, while buoyant force is the upward force exerted by the fluid.

Q5: How is this applied in real-world scenarios?
A: Buoyancy calculations are used in ship design, submarine operations, hot air balloons, and determining whether objects will float or sink in different fluids.
