Energy info

Energy is a property that can be transferred and converted among objects, but cannot be created or destroyed. The SI unit is the Joule, which equates to the work required to move an object through 1 meter, against a force of 1 newton. In addition, the etymology of the joule is John Prescott Joule, an English Physicist who worked on thermodynamics. Furthermore, he worked with Lord Kelvin on what became the Kelvin temperature scale.

There are many other comparable ways to measure the joule besides J = Nm. It is also defined as J = (kg⋅m²)/s² , J = W⋅s , J = Pa⋅m³ , J = C⋅V . And so, this covers the mechanical, power, pressure and electrical applications of the joule respectively.

The thermochemical calorie was firstly stated to be a measure of the energy needed to heat one gram of water by one degree. However, that differs depending on the temperature and pressure of the water to begin with, so 1 calorie = 4.184 J is now the standard.

Similarly, the British Thermal Unit is equivalent to the energy taken to raise the temperature of one pound of water by 1 fahrenheit.

The electronvolt has a value that is equal to the charge of an electron.
