Definition of kinetic energy in US English:

kinetic energy


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

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