:The energy that a substance has because   
                     of the  motion of its particles
                     T.E. = K.E. = ½ mm2
  age  aver                      average speed of a large
kinetic energy                   ensemble of particles
Associated with moving particles or objects
K.E. = ½ mm2
       (mechanical: i.e. the energy stored in a  tightly     
                             wound spring
 water stored in a reservoir behind a hydroelectric dam
   chemical: energy stored in chemical bonds)
