## Anisotropy energy

Anisotropic energy is energy that is directionally specific. The word anisotropy means "directionally dependent", hence the definition. The most common form of anisotropic energy is magnetocrystalline anisotropy, which is commonly studied in ferrimagnets. In ferrimagnets, there are islands or domains of atoms that are all coordinated in a certain direction; this spontaneous positioning is often called the "easy" direction, indicating that this is the lowest energy state for these atoms. In order to study magnetocrystalline anisotropy, energy is applied to the domain, which causes the cryst ...

## Binding energy

In physics, binding energy is the minimum energy required to disassemble a system of particles into separate parts. This energy is equal to the mass defect minus the amount of energy, or mass, that is released when a bound system is created, and is what keeps the system together.

## Characteristic energy

In astrodynamics, the characteristic energy is a measure of the excess specific energy over that required to just barely escape from a massive body. The units are length 2  time −2, i.e. velocity squared or twice the energy per mass. Every object in a 2-body ballistic trajectory has a constant specific orbital energy ϵ {\displaystyle \epsilon } equal to the sum of its specific kinetic and specific potential energy: ϵ = 1 2 v 2 − μ r = constant = 1 2 C 3, {\displaystyle \epsilon ={\frac {1}{2}}v^{2}-{\frac {\mu }{r}}={\text{constant}}={\frac {1}{2}}C_{3},} where μ = G M {\displaystyle \mu = ...

## Conservation of energy

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all forms of energy that were released in the explosion, such as the kinetic energy and potential energy of the pieces, as well as heat and sound, one will get the exact decreas ...

## Dark energy

In physical cosmology and astronomy, dark energy is a term that describes an unknown form of energy that affects the universe on the largest scales. The first observational evidence for its existence came from supernovae measurements, which showed that the universe does not expand at a constant rate; rather, the expansion of the universe is accelerating. Understanding the evolution of the universe requires knowledge of the starting conditions and what it consists of. Prior to these observations, the only forms of matter-energy known to exist were ordinary matter, dark matter, and radiation ...
