#force  the physical influence that produces a change in a physical quantity; "force equals mass times acceleration"
  subtype:  aerodynamic_force  chemical_attraction {attractive_force repulsive_force} {centrifugal_force centripetal_force}  cohesion  Coriolis_force  impetus  Lorentz_force  moment.force  propulsion  pull.force  push.force  reaction.force  stress  torsion  magnetomotive_force  life_force
  supertype:  physical_phenomenon  a natural phenomenon involving the physics of matter and energy
     supertype:  natural_phenomenon__naturalphenomenon  all non-artificial phenomena
        supertype:  phenomenon  any state or process known through the senses rather than by intuition or reasoning
           supertype:  process__proces__physicalsituation  intuitively, the class of things that happen and have temporal parts or stages; examples include extended events like a football match or a race, actions like pursuing and reading, and biological processes; sumo#process is not identical to pm#situation because an instance of pm#situation is not necessarily an instance of sumo#physical
              supertype:  situation  something that "occurs" in a real/imaginary region of time and space
                 supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
              supertype:  process_or_process_description
                 supertype:  processing_thing
                    supertype:  thing_playing_some_role  category to classify things according to roles/viewpoints; classification under this category is application-dependant
                       supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
              supertype:  physical__physical_thing  an entity that has a location in space-time; locations are themselves understood to have a location in space-time; click here for more details on the identical category sowa#physical_thing
                 supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
