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.
In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.ll of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.
