Magnesium monohydride is a molecular gas with formula MgH that exists at high temperatures, such as the atmospheres of the Sun and stars. [2] It was originally known as magnesium hydride, although that name is now more commonly used when referring to the similar chemical magnesium dihydride .
There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is ...
Magnesium hydride is the chemical compound with the molecular formula MgH 2. It contains 7.66% by weight of hydrogen and has been studied as a potential hydrogen storage medium. It contains 7.66% by weight of hydrogen and has been studied as a potential hydrogen storage medium.
MgH 2 → Mg + H 2. Magnesium can form compounds with the chemical formula MgX 2 (X=F, Cl, Br, I) with halogens. Except for magnesium fluoride, the halides are easily soluble in water, but the solubility of magnesium fluoride is higher than that of other alkaline earth metal fluorides.
The gravitational potential (V) at a location is the gravitational potential energy (U) at that location per unit mass: =, where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity.
For two pairwise interacting point particles, the gravitational potential energy is the work done by the gravitational force in bringing the masses together: = =, where is the displacement vector between the two particles and denotes the scalar product.

e u = g h Specific potential energy is potential energy of an object per unit of mass of that object. In a gravitational field it is the acceleration of gravity times height, e u = g h {\displaystyle e_{u}=gh} .
