The Joule, which has the symbol J, is the standard unit used to calculate energy and work performed in physics. In dynamics, when a force of 1 Newton is applied to an object and drives a distance of 1 metre, 1 Joule is the energy transmitted. Energy is a term which in daily life seems to be used a lot. Although it is sometimes used very loosely, it does have a clear physical sense. Energy is a calculation of the potential of anything to do work.

It is not a substance of material origin. The energy, in many ways, can be processed and weighed. Although we sometimes hear people complaining about the consumption of electricity, energy is never destroyed. It is only moved, doing work in the process, from one form to another. Some sources of energy, such as low-level thermal energy, are less beneficial to us than others. The consumption or production of energy resources, such as gas, oil, or wind, is easier to speak about than the consumption of energy itself.
