Explanation

Kinetic energy is the energy possessed by an object due to its motion, calculated by the formula KE = 1/2mv² where m is mass and v is velocity. It exists at all scales from subatomic particles to astronomical objects, and is not limited to living organisms or deep space phenomena. The term derives from the Greek word 'kinesis' meaning motion.
