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).
The currency for performing work is called : Energy. And Energy's unit of measurement is : Joule. The amount of energy you've inputed will always equal the output. For example, in order to do a 500 joules of work, you need 500 joules of energy.
