kinetic energy

English

Noun

kinetic energy (countable and uncountable, plural kinetic energies)

   • 1959 March, “The 2,500 h.p. electric locomotives for the Kent Coast electrification”, in Trains Illustrated, page 123:

     As on Nos. 20001-3, the motor and generator armature shafts of the new locomotive each carry a heavy flywheel to provide kinetic energy and help maintain the speed of the motor-generator set during interruptions of supply, as at breaks in the continuity of the conductor rail.

2. Energetic fast-paced activity.
   • 2023 March 14, Caryn James, “John Wick: Chapter 4: 'Soars above most action films'”, in BBC‎^[1]:

     Reeves' action moves and his sincerity, even when Wick is at his most stern, perfectly capture the blend of emotion and kinetic energy that define the films.
