Definition of kinetic energy in English:

kinetic energy


mass nounPhysics
  • Energy which a body possesses by virtue of being in motion.

    ‘energy above that needed to ionize the molecule is carried away as kinetic energy of the electron ejected’
    Compare with potential energy
    count noun ‘particles with low kinetic energies’
    • ‘A moving particle will carry with it the energy of its motion, which the physicists call kinetic energy.’
    • ‘The molecules convert their kinetic energy into potential energy when they rise into the air just like the ball did.’
    • ‘The energy flow resulting from transforming kinetic energy into potential energy is heat.’
    • ‘By lowering the centre of gravity, some potential energy is removed from the system and converted to kinetic energy - the energy of motion.’
    • ‘One way energy is conserved is through the transformation of an object's potential energy into kinetic energy.’
