Question 1

What is a Buoyancy Calculator?

Accepted Answer

Buoyancy is the upward force a fluid exerts on a submerged or floating object, equal to the weight of fluid displaced (Archimedes' Principle). An object floats when buoyant force equals or exceeds its weight; it sinks when weight exceeds buoyant force.

Question 2

How does the Buoyancy Calculator work?

Accepted Answer

Buoyant force Fb = ρ_fluid × g × V_displaced Then: ρ_fluid = fluid density (water = 1,000 kg/m³) Then: g = gravitational acceleration (9.81 m/s²) Then: V_displaced = volume of fluid displaced (= object volume if fully submerged).

Question 3

Can you give an example of how to use the Buoyancy Calculator?

Accepted Answer

Example: Input 0.1m³ wooden block in water gives a result of Fb = 1000 × 9.81 × 0.1 = 981 N (If block weighs less than 981N, it floats).

Question 4

Is the Buoyancy Calculator free to use?
