Agreement With The Law Of Conservation Of Energy

Since energy is a preserved size, the net production of energy must be zero in the barrel. Now, the net transport of any quantity in a system is only the difference between the entry and production of that quantity; And since there is no energy transport in this system, the net transport of energy is only the negative of energy power. The resulting literal descriptive form of the combined energy conservation equation and the energy balance equation for this system is many technical applications only include the conversion of energy between two or three types. For example, in the case of dynamic problems, energy conservation takes into account two types of energy, that is, kinetics and potential (in some cases friction work), neglecting the effect of other forms such as chemical, thermal or electrical forms. In the case of chemical reactions, energy preservation includes thermal and chemical energies, and the action of other forms of energy is ignored. In most thermodynamic problems, the principle of energy saving applied to non-reactive systems takes into account thermal and mechanical energies. Thermal energy: the energy inside an object due to the random movement of its atoms and molecules that declares the temperature of the object will therefore be the evacuation of energy relative to time zero. Take the time deviation of Eq. (119) and if it is zero, Table 2 gives some yields of mechanical equipment and human activities. In a coal-fired power plant, for example, about 40% of the chemical energy in coal becomes useful electrical energy. The other 60% turns into other (perhaps less useful) forms of energy, such as thermal energy, which is then released into the environment through flue gases and cooling towers. When does EO play a role? An example occurs when a person eats.

Food is oxidized by the release of carbon dioxide, water and energy. Some of this chemical energy is converted into kinetic energy as the person moves, into potential energy, if the person changes height, and into thermal energy (another form of EO). Step 2. Examine all the forces involved and determine whether you know or get the potential energy from the work of the forces. Then use step 3 or step 4. All types of energy and work can be included in this very general statement of energy savings. Kinetic energy is KE, work performed by a conservative force is represented by pe, work performed by non-conservative forces is Wnc, and all energies other than EO are included. This equation applies to all previous examples; in these situations, the EO was constant, and so it was deduced and not directly taken into account.

A second type of approach postulates a random process that breaks the uncertainty of the system and eliminates its vagueness. A third solution involves a large number of universes. What we call a measure corresponds in a way to a division of our universe into many branches, one of which corresponds to any possible result. All these ideas renounce the problematic recipe of measurement. No one is without problems, but that is what exists.

This applies to the total energy of the systems, although several observers disagree on the energy value. Also and invariant for all observers is the invariant mass which is the minimum mass of the system and the energy that can be seen by any observer and which is defined by the energy-impulse relationship. . . .
