The emergence of energy physics
Julius Mayer, a German physicist, was the first person to state the law of the conservation of energy, in an 1842 scientific paper.
Answer:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. This is particularly confusing in the case of non-conservative forces, where energy is converted from mechanical energy into thermal energy, but the overall energy does remain the same. The only way to use energy is to transform energy from one form to another.
The amount of energy in any system, then, is determined by the following equation:
UT=Ui+W+Q
UT is the total internal energy of a system.
Ui is the initial internal energy of a system.
W is the work done by or on the system.
Q is the heat added to, or removed from, the system.
