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 equals 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)
• weight — Weight of the fluid displaced by the object (Newtons)

Explanation: The buoyant force is equal to the weight of the fluid that the object displaces when submerged.

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 analyzing fluid dynamics in various engineering applications.

4. Using the Calculator

Tips: Enter the weight of the displaced fluid in Newtons. The value must be greater than zero for accurate calculation.

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 is buoyant force related to density?
A: Buoyant force depends on the density of the fluid and the volume of fluid displaced. For a given volume, higher fluid density results in greater buoyant force.

Q3: Why do objects float or sink?
A: Objects float when the buoyant force equals or exceeds their weight, and sink when their weight exceeds the buoyant force.

Q4: Does shape affect buoyant force?
A: The shape affects how much fluid is displaced, which directly determines the buoyant force according to Archimedes' principle.

Q5: How is this used in real-world applications?
A: Buoyancy calculations are crucial in ship design, submarine operations, hot air ballooning, and various hydraulic engineering applications.
