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 joule (J) is the unit of measure for energy used in the International System of Units (SI), and the one accepted in scientific circles.The unit is used in all equations and calculations involving energy.he joule is a unit of measure for energy. Sitting quietly, a person generates 100 J of heat every second. Individuals pay per kilowatt hour for the electricity they use in their homes. The amount of energy required to lift an apple 1 meter (3.3 feet) is roughly equivalent to 1 Joule.
