DictionarySeepotential energylatent energy
po·ten·tial en·er·gythe energy, existing in a body by virtue of its position or state of existence, which is not being exerted at the time. Synonym(s): energy of position, latent energyenergy (en'er-je) [Gr. energeia, activity] In physics, the capacity to do work, effect change. Energy is manifested in motion (kinetic energy) or position or chemical bonding (potential energy). Changes in energy may be physical, chemical, or both. Movement of a part of the body shortens and thickens the muscles involved and temporarily changes the position and size of cells, but intake of oxygen in the blood combined with glucose and fat creates a chemical change and produces heat (energy) and waste products within the cells; fatigue is produced in turn. See: calorie; energy expenditure, basal conservation of energyThe principle according to which energy cannot be created or destroyed, but is transformed into other forms. kinetic energyThe energy of motion. It consists of the mass of an object and its velocity. latent energyPotential energy.monochromatic infrared energy Abbreviation: MIRE Exposure of the body to a light source whose wavelength is 880 nm. It has been studied as a potential treatment for diabetic neuropathy, musculoskeletal trauma and pain, and cutaneous sores. phosphate-bond energyEnergy derived from phosphorylated compounds such as adenosine triphosphate (ATP) and creatine phosphate. potential energyEnergy stored but not actively used. It includes, for example, the energy stored in chemical bonds or in objects based on their position in space. Synonym: latent energyradiant energyA form of energy transmitted through space. Radio waves, infrared waves, visible rays, ultraviolet waves, x-rays, gamma rays, and cosmic rays are examples of energy in this form. See: electromagnetic spectrum for tablestray energyElectricity or heat accidentally released during electrosurgery into tissues that were not targeted for cautery or cutting.LegalSeeEnergy |
