  1. 1Work and powerForce through a distance. The rating plate on every motor is this idea, in watts.
  2. 2Kinetic and potentialBenchTwo ledgers. Motion, and configuration. Springs and heights are the configuration ledger.
  3. 3Conservation and efficiencyEnergy is conserved. Useful energy is not. That difference is the entire thermal sciences.
