  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Energy  \En"er*gy\,  n.;  pl  {Energies}.  [F.  ['e]nergie,  LL 
  energia,  fr  Gr.?,  fr  ?  active;  ?  in  +  ?  work  See  {In},  and 
  {Work}.] 
  1.  Internal  or  inherent  power;  capacity  of  acting,  operating, 
  or  producing  an  effect,  whether  exerted  or  not  as  men 
  possessing  energies  may  suffer  them  to  lie  inactive. 
 
  The  great  energies  of  nature  are  known  to  us  only  by 
  their  effects.  --Paley. 
 
  2.  Power  efficiently  and  forcibly  exerted;  vigorous  or 
  effectual  operation;  as  the  energy  of  a  magistrate. 
 
  3.  Strength  of  expression;  force  of  utterance;  power  to 
  impress  the  mind  and  arouse  the  feelings;  life;  spirit;  -- 
  said  of  speech,  language,  words  style;  as  a  style  full 
  of  energy. 
 
  4.  (Physics)  Capacity  for  performing  work 
 
  Note:  The  kinetic  energy  of  a  body  is  the  energy  it  has  in 
  virtue  of  being  in  motion.  It  is  measured  by  one  half 
  of  the  product  of  the  mass  of  each  element  of  the  body 
  multiplied  by  the  square  of  the  velocity  of  the 
  element,  relative  to  some  given  body  or  point.  The 
  available  kinetic  energy  of  a  material  system 
  unconnected  with  any  other  system  is  that  energy  which 
  is  due  to  the  motions  of  the  parts  of  the  system 
  relative  to  its  center  of  mass.  The  potential  energy  of 
  a  body  or  system  is  that  energy  which  is  not  kinetic; 
  --  energy  due  to  configuration.  Kinetic  energy  is 
  sometimes  called  actual  energy.  Kinetic  energy  is 
  exemplified  in  the  vis  viva  of  moving  bodies,  in  heat, 
  electric  currents,  etc.;  potential  energy,  in  a  bent 
  spring,  or  a  body  suspended  a  given  distance  above  the 
  earth  and  acted  on  by  gravity.
