  2. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Fire is an example of energy transformation Energy transformation using Energy Systems Language. Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics, energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat.

    World War II is a series of books published by Time-Life that chronicles the Second World War. Each book focused on a different topic, such as the resistance, spies, the home front but mainly the battles and campaigns of the conflict.

  4. Mass–energy equivalence - Wikipedia

    en.wikipedia.org/wiki/Mass–energy_equivalence

    Mass–energy equivalence states that all objects having mass, or massive objects, have a corresponding intrinsic energy, even when they are stationary.In the rest frame of an object, where by definition it is motionless and so has no momentum, the mass and energy are equal or they differ only by a constant factor, the speed of light squared (c 2).

  7. Second law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Second_law_of_thermodynamics

    The second law of thermodynamics is a physical law based on universal empirical observation concerning heat and energy interconversions.A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter (or 'downhill' in terms of the temperature gradient).

  8. Conservation law - Wikipedia

    en.wikipedia.org/wiki/Conservation_law

    Conservation laws are fundamental to our understanding of the physical world, in that they describe which processes can or cannot occur in nature. For example, the conservation law of energy states that the total quantity of energy in an isolated system does not change, though it may change form.
