Buoyant Force Calculator
F_b = ρ · g · V
Instructions
Enter the fluid density (e.g., water = 1000 kg/m³), the volume of fluid displaced by the object, and gravitational acceleration. Click Calculate to get the buoyant force in newtons.
Formula
F_b = ρ · g · V
- ρ: Fluid density (kg/m³)
- g: Gravitational acceleration (m/s²)
- V: Displaced volume (m³)
Common Questions
What determines whether an object floats?
If the buoyant force is equal to or greater than the object's weight, it floats. Otherwise, it sinks.
Does shape matter?
Buoyant force depends on displaced volume, not directly on shape. However, shape affects how much volume is displaced for a given mass.
