## 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)mv*^{2}, where*m*represents the mass of the object and*v*is its velocity.## ki·net·ic en·er·gy

(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).**the energy possessed by an object due to its movement along a straight or a curved line. May be calculated as ½ mv**

*translational kinetic energy*^{2}where m is the mass of the object and v is linear velocity.

**the mechanical energy possessed by an object due to its rotation about an axis. May be calculated as ½ Iw**

*rotational kinetic energy*^{2}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**

the energy of motion.
