The methods of standardization or calibration employed have much in common even in the cases that appear most diverse.
The joule (/ËdÊuËl/), symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred (or work done) to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or NÂ·m).
Use of the term embodied energy for this concept was modified in 1986 when David Scienceman, a visiting scholar at the University of Florida from Australia, suggested the term âemergyâ and emjoule or emcalorie as the unit of measure to distinguish emergy units from units of available energy.
