In the 8th century, a priest in Lanciano, Italy was experiencing doubts about the real presence of Jesus in the Eucharist. In the middle of saying Mass, he said the words of consecration (âThis is my body,â âThis is my blood) and saw the bread and wine transform into real human flesh and blood.
Energy is usually defined as the ability to do work. This is an anthropocentric and utilitarian perspective of energy; however, it is a useful definition for engineering where the aim of machines is to convert energy to work.
It is not that difficult to distinguish between Energy and power. While energy is the ability to do work, Power is its measurement, which calculates the time by which the energy has been used. Well, Energy is what one delivers and Power is the rate at which it is delivered.Energy is the capability to do something. For example, energy is used for moving the car or heating the home or lighting the night or even flying an aeroplane.The basic unit of Energy is Joule but normally it is termed in watt-hour or kilowatt-hour. Energy appears in many forms and is often expressed in multiple units.ell, in another words Power is âwattâ and Energy is âwatt-hourâ. Another difference is that energy can be stored whereas power cannot be stored. While energy comes with a time component, Power is an instantaneous quantity.
