# Kinetic energy

From Glossary of Meteorology

## kinetic energy

The energy that a body possesses as a consequence of its motion, defined as one- half the product of its mass and the square of its speed, (1/2)

*m'***v**^{2}.

The kinetic energy per unit volume of a fluid parcel is thus (1/2)ρ

*v*^{2}, where ρ is the density and*v*the speed of the parcel.*See*potential energy.
