Atomic energy

Atomic energy or energy of atoms is energy carried by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility of atomic energy. The term was popularized by H. G. Wells in the phrase, "splitting the atom", devised at a time prior to the discovery of the nucleus. Atomic energy may include: The energy of inter-atomic or chemical bonds, which holds atoms together in compounds. Radioactive decay, the set of various processes by which unstable atomic nuclei nuclides emit subatomic particles. Nuclear reaction, a process in which nuclei or nuclear particles inte ...

                                               

Elastic energy

Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner. Elasticity theory primarily develops formalisms for the mechanics of solid bodies and materials. The elastic potential energy equation is used in calculations of positions of mechanical equilibrium. The energy is potential as it will be converted into other forms of energy, such as kinetic energy and so ...

                                               

Electrical energy

Electrical energy is energy derived from electric potential energy or kinetic energy. When used loosely, electrical energy refers to energy that has been converted from electric potential energy. This energy is supplied by the combination of electric current and electric potential that is delivered by an electrical circuit. At the point that this electric potential energy has been converted to another type of energy, it ceases to be electric potential energy. Thus, all electrical energy is potential energy before it is delivered to the end-use. Once converted from potential energy, electri ...

                                               

Gravitational energy

Gravitational energy is the potential energy a physical object with mass has in relation to another massive object due to gravity. It is potential energy associated with the gravitational field. Gravitational energy is dependent on the masses of two bodies, their distance apart and the gravitational constant. In everyday cases i.e. close to the Earths surface, the gravitational field is considered to be constant. For such scenarios the Newtonian formula for potential energy can be reduced to: U = m g h {\displaystyle U=mgh} where U {\displaystyle U} is the gravitational potential energy, m ...

                                               

Kinetic energy

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is 1 2 m v 2 {\the style property display the value of {\begin{smallmatrix} ...

                                               

Magnetic energy

Magnetic energy and electrostatic potential energy are related by Maxwells equations. The potential energy of a magnet of magnetic moment m {\displaystyle \mathbf {m} } in a magnetic field B {\displaystyle \mathbf {B} } is defined as the mechanical work of the magnetic force on the re-alignment of the vector of the magnetic dipole moment and is equal to: E p, m = − m ⋅ B {\displaystyle E_{\rm {p,m}}=-\mathbf {m} \cdot \mathbf {B} } while the energy stored in an inductor of inductance L {\displaystyle L} when a current I {\displaystyle I} flows through it is given by: E p, m = 1 2 L I 2. {\ ...

                                     

ⓘ Forms of energy

  • hybrid. The energy from moving masses of water - a popular form of hydroelectric power generation. Tidal power generation comprises three main forms namely:
  • energy equation is used in calculations of positions of mechanical equilibrium. The energy is potential as it will be converted into other forms of energy
  • Electric potential energy or Electrostatic potential energy is a potential energy measured in joules that results from conservative Coulomb forces
  • excess electrical energy during periods of low demand and storing it in other forms until needed on an electrical grid. The energy is later converted
  • overstating forms of energy with poor conversion efficiency e.g. coal, gas and nuclear and understating forms already accounted for in converted forms e.g
  • within a molecule or otherwise. Chemical energy of a chemical substance can be transformed to other forms of energy by a chemical reaction. As an example
  • Office of Energy Efficiency and Renewable Energy EERE is an office within the United States Department of Energy Formed from other energy agencies
  • Energy quality is the contrast between different forms of energy the different trophic levels in ecological systems and the propensity of energy to convert
  • term energy is used by writers and practitioners of various esoteric forms of spirituality and alternative medicine to refer to a variety of claimed
