Medical Definition of Energy

1. Typically defined as the ability to do work. Power is the rate at which work is done, or the rate at which energy is changed. Work characterises the degree to which the properties of a substance are transformed. Energy exists in many forms, which can be converted from one to another in various ways. Examples include: gravitational energy, electrical energy, magnetic and electric field energy, atomic binding energy (a form of electrical energy really), nuclear binding energy, chemical energy (another form of electrical energy), in addition to these forms of potential energy there are also kinetic energy (energy due to motion), and thermal energy (heat, a form of kinetic energy where the motion is due to thermal vibrations/motions), and so on.
