# Energy conservation

## General

The energy conservation law states that if no energy is taken to or away, that energy is conserved in a then so-called closed system. So that energy can neither be lost, nor created. Albert Einstein and other physicists of his time have kept the energy conservation law as a high theoretical law and conducted much out of it. The absolute theory, of course, believes in the conservation of energy, even if she sees that the concept of total energy is controversial.

## Einstein and the conservation of energy

Albert Einstein discovered E = m * c ². Nevertheless, the observations on the energy conservation law is somewhat vague. He sees in the end of his lectures m * c ² only as rest energy, as E (0). Therefore it is needed for the conservation of energy to add different energies in his opinion. He adds the potential and kinetic energy of the energy conservation law of mechanics. The absolute theory sees this as wrong, as the E = m * c ² is not only the correct description of the total energy as it can also be conducted from the equivalence of space and time, but that it also specifies the maximum of energy. Ultimately, the energy of the mass and the speed is set to the square together. Since the rate is not higher than the speed of light c can be, and the mass stays the same, there can be no higher energy than m * c ². Since then how Einstein does, by adding the potential, the kinetic and other forms of energy can not be right.

## Energy and absolute theory

After the absolute theory is E = m * c ² the total energy of a system again. This is also evident from the equivalence of space and time, which also took Einstein when he said, moving in absolute space-time is all with c according to Brian Greene. Kinetic and potential energy are just some of this energy and not additive quantities. One could then use the mass conservation law derive precisely from this equivalence of mass and energy. To accept the principle of energy conservation an energy higher than E = m * c ² is simply wrong.

## Energy conservation law in mechanics

The mechanical energy of a system with no external influence also remain constant. Then E (pot) + E (kin) = const. Figuratively one can envision that with the pendulum. When the pendulum swings up against the force of gravity, it gains potential energy and loses in speed, ie kinetic energy. However, the pendulum is at the apex, so at the lowest point of its curve, it gains the right speed, and loses, of course, in the gravitational field the potential energy.

## Conservation of energy and the first thermodynamic law

After the first law of thermodynamics the energy is conserved. It says that the difference in internal energy of a system is equal to the difference of the heat supplied minus the used work. If both values ​​are zero, as is the case in a closed system, the internal energy is obtained.
