## ki·net·ic en·er·gy (K),

the energy of motion.

## kinetic energy (KE)

Etymology: Gk, kinesis, motion, energeia
the energy possessed by an object by virtue of its motion. It is expressed by the formula KE = (½)mv2, where m represents the mass of the object and v is its velocity.

(ki-net'ik en'ĕr-jē)
The energy of motion.

## kinetic energy

the energy possessed by a body or object due to movement. Can be translational or rotational (or both). translational kinetic energy the energy possessed by an object due to its movement along a straight or a curved line. May be calculated as ½ mv2 where m is the mass of the object and v is linear velocity. rotational kinetic energy the mechanical energy possessed by an object due to its rotation about an axis. May be calculated as ½ Iw2 where I is moment of inertia and w is angular velocity. Measured in joules (J).

## kinetic energy,

n a property of a particle that describes the energy of motion and directly correlates with the particle's rate of motion. For example, transfer of gaseous particles is an important factor in the field of aromatherapy.

## kinetic

pertaining to or producing motion.

kinetic energy
