1. What is Buoyant Force?

Buoyant force is the upward force exerted by a fluid that opposes the weight of 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)
• \( V \) — Volume of displaced water (cubic meters)
• 1000 — Density of fresh water (kg/m³)
• 9.81 — Acceleration due to gravity (m/s²)

Explanation: This formula calculates the weight of the water displaced by an object, which equals the buoyant force acting on that object.

3. Importance of Buoyant Force Calculation

Details: Calculating buoyant force is essential for designing ships, submarines, and other floating structures. It helps determine whether an object will float, sink, or remain neutrally buoyant in water.

4. Using the Calculator

Tips: Enter the volume of water displaced by the object in cubic meters. The volume must be a positive value greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Does this formula work for salt water?
A: No, this formula is specifically for fresh water. For salt water, you would need to use a higher density value (approximately 1025 kg/m³).

Q2: What if my object is partially submerged?
A: For partially submerged objects, use only the volume of the part that is underwater in your calculation.

Q3: How does object shape affect buoyant force?
A: The shape doesn't directly affect the buoyant force - only the volume of displaced water matters. However, shape affects whether an object will float stable or tip over.

Q4: Why is the density of water 1000 kg/m³?
A: This is the standard density of pure fresh water at 4°C. Density changes slightly with temperature and impurities.

Q5: Can I use this for other fluids?
A: Yes, but you need to replace the density value (1000) with the density of the specific fluid you're working with.
