## Buoyant Force

`\( F_{\text A} \)`Unit

`\( \text{N} \)`

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

`\( \class{blue}{\rho} \)`Unit

`\( \frac{ \text{kg} }{ \text{m}^3} \)`

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

`\( \class{red}{V} \)`Unit

`\( \text{m}^3 \)`

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

## Gravitational acceleration

`\( g \)`Unit

`\( \frac{m}{s^2} \)`

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