How is work measured?

The concept of "work" has many interpretations. First of all, this term means mechanical work, but there are also many other scientific concepts. So, for example, you can select work in thermodynamics, electrical circuits, where it is also called power by another. There is also the concept of kinetic and potential energy. All these physical quantities are a quantitative scalar measure of the force of action. It depends on a certain numerical value, the movement of a point of a system or body and the direction of force.

Find out what is measured in the work? In the international system SI, the unit of measure of work is considered to be joules. In one Joule there is 1 kg · m² / s² or 1 N · m, where N is Newtons. However, no less popular in the GHS (system type centimeter-gram-second) is the measurement of work in ergs. In this case, 1 ERG equals 1 g · cm2/from2or 10−7J.
