## Buoyant Force

Unit
Force experienced by a body in the opposite direction to gravity when this body is immersed in a liquid (e.g. water). The body experiences a buoyancy.

## Density

Unit
Mass density of the liquid. It tells you how heavy one cubic meter of the liquid is.

For example, the density of water is: $$\rho ~=~ 10^{-3} \, \frac{ \text{kg} }{ \text{m}^3}$$.

## Volume

Unit
Volume of the liquid displaced by the immersed body. This is exactly the volume of the body immersed in the liquid.

## Gravitational acceleration

Unit
The gravitational acceleration is experienced by a body in the gravitational field of a planet. On the earth the gravitational acceleration is: $$g ~=~ 9.8 \, \frac{\text m}{\text{s}^2}$$.
