   In an internal combustion engine, energy is generated and then channeled   
   in one direction, and that scalar energy becomes a vector force.   
      
   Therefore, we can consider energy as a set of equal and opposite forces   
   directed in all possible directions.   
      
   Thus, energy, despite being composed of vector forces, is a scalar   
   simply because none of these forces prevails over the opposing force.   
      
   However, if at a certain point one of these forces increases or   
   decreases without the opposing force doing the same, part of this energy   
   becomes a vector force.   
      
   Is this correct?

   [[Mod. note --   
   No, in general it's not correct.  Energy and force are two different   
   things, and it's not correct is to say that energy is composed of   
   forces.   
      
   Energy is the ability to do work, and an important special case of   
   this is mechanical work, where a force acts on a body which moves.   
      
   But, there are (other) types of energy which aren't associated with   
   mechanical work.  For example, think about the energy carried by   
   electromagnetic radiation (e.g., sunlight), or more generally, by the   
   energy contained in a (large) set of photons.
