- Archimedes Principle states that when a body is wholly or partially immersed in a fluid it experiences an upthrust equal to the weight of the fluid displaced.
- Upthrust/Buoyant force is an upward force exerted by a fluid on an object immersed in it.
- Mathematically, we write
F = Upthrust/Buoyant Force
ρ = Density of the liquid
V = Volume of the displaced liquid
g = Gravitational field strength
