Joule and energy

The formulation of the mechanical equivalent of heat can be taken as a crucial step towards the formulation of the principle of energy conservation. Joule demonstrated in a series of experiments that mechanical work (which he still called 'mechanical force') can be converted at a constant ratio into heat.
