  2. Laws of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Laws_of_thermodynamics

    For example, when a machine (not a part of the system) lifts a system upwards, some energy is transferred from the machine to the system. The system's energy increases as work is done on the system and in this particular case, the energy increase of the system is manifested as an increase in the system's gravitational potential energy. Work ...

  3. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    The word energy derives from the Ancient Greek: ἐνέργεια, romanized: energeia, lit. 'activity, operation', [4] which possibly appears for the first time in the work of Aristotle in the 4th century BC. In contrast to the modern definition, energeia was a qualitative philosophical concept, broad enough to include ideas such as happiness ...

  4. Outline of physics - Wikipedia

    en.wikipedia.org/wiki/Outline_of_physics

    Physics – natural science that involves the study of matter [1] and its motion through spacetime, along with related concepts such as energy and force. [2] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [3] [4] [5]

  5. Second law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Second_law_of_thermodynamics

    [5] [6] Historically, the second law was an empirical finding that was accepted as an axiom of thermodynamic theory. Statistical mechanics provides a microscopic explanation of the law in terms of probability distributions of the states of large assemblies of atoms or molecules. The second law has been expressed in many ways.

  6. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    Equilibrium thermodynamics is the study of transfers of matter and energy in systems or bodies that, by agencies in their surroundings, can be driven from one state of thermodynamic equilibrium to another. The term 'thermodynamic equilibrium' indicates a state of balance, in which all macroscopic flows are zero; in the case of the simplest ...
