Physics of Energy

• Energy
• Activation energy explains the differences in the speeds of various chemical reactions
• Alternative energy indexes
• Bioenergetics
• Chemical energetics
• Energy in physical cosmology
• Energy in Earth science that is responsible for the macroscopic transformations on the planet Earth
• Electricity
• Exergy
• Green energy
• Orders of magnitude (energy) – list describes various energy levels between 10−31 joules and 1070 joules
• Thermodynamics
• Perpetual motion
• Heat
• History of energy
• Forms of energy, the forms in which energy can be defined
• Energy transformation, relating to energy's changes from one form to another.
• Energy (signal processing), the inner product of a signal in the time domain
• Energy density spectrum, relating to the distribution of signal energy over frequencies.
• Potential energy, the form of energy that is due to position of an object
• Kinetic energy, the form of energy as a consequence of the motion of an object or its constituents
• Mechanical energy, the potential energy and kinetic energy present in the components of a mechanical system.
• Binding energy, a concept explaining how the constituents of atoms or molecules are bound together
• Bond energy, a measure of the strength of a chemical bond
• Nuclear energy, energy that is the consequence of decomposition or combination of atomic nuclei
• Osmotic power,or salinity gradient power and blue energy, is the energy available from the difference in the salt concentration between seawater and river water
• Gibbs free energy, a related concept in chemical thermodynamics that incorporates entropy considerations too
• Helmholtz free energy, a thermodynamic potential that measures the "useful" work obtainable from a closed thermodynamic system at a constant temperature, useful for studying explosive chemical reactions
• Elastic energy, which causes or is released by the elastic distortion of a solid or a fluid
• Ionization energy – the (IE) of an atom is the energy required to strip it of an electron.
• Interaction energy, the contribution to the total energy that is a result of interaction between the objects being considered
• Internal energy – (abbreviated E or U) the total kinetic energy due to the motion of molecules (translational, rotational, vibrational) and the total potential energy associated with the vibrational and electric energy of atoms within molecules.
• Negative energy
• Energy conversion – process of converting energy from one form to another
• Dark energy, used to explain some cosmological phenomena
• Energy quality, empirical experience of the characteristics of different energy forms as they flow and transform
• Energy density, amount of energy stored in a given system or region of space per unit volume, or per unit mass
• Energy flow, flow of energy in an ecosystem through food chains
• Energetics, the scientific study of energy flows under transformation
• Stress-energy tensor, the density and flux of energy and momentum in space-time; the source of the gravitational field in general relativity
• Food energy, energy in food that is available
• Primary energy – Energy contained in raw fuels and any other forms of energy received by a system as input to the system.
• Radiant energy – energy that is transported by waves
• Rotational energy – An object's rotational energy or angular kinetic energy is part of its total kinetic energy
• Solar radiation – radiant energy emitted by the sun, particularly electromagnetic energy
• Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power - mainly electricity, dynamic tidal power, tidal lagoons, Tidal barrage
• Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter (WEC).
• Wind energy is the kinetic energy of air in motion;Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships
