			In [[physics]] and [[mechanics]], '''mass distribution''' is the spatial distribution of [[mass]] within a [[solid]] body. In principle, it is relevant also for [[gas]]es or [[liquid]]s, but on earth their mass distribution is almost homogeneous.

			==Astronomy==
			In [[astronomy]] mass distribution has decisive influence on the development e.g. of [[nebula]]e, [[star]]s and [[planet]]s.
			The mass distribution of a '''solid''' defines its [[center of gravity]] and influences its dynamical behaviour - e.g. the [[oscillation]]s and eventual [[rotation]].

			==Mathematical modelling==
			A mass distribution can be modeled as a [[Measure (mathematics)\|measure]]. This allows point masses, line masses, surface masses, as well as masses given by a volume density function. Alternatively the latter can be generalized to a [[distribution (mathematics)\|distribution]]. For example, a point mass is represented by a [[Dirac_delta#Generalizations\|delta function defined in 3-dimensional space]]. A surface mass on a surface given by the equation ''f(x,y,z)'' = 0 may be represented by a density distribution ''g(x,y,z) δ (f(x,y,z))'', where <math>g/\mid \nabla f \mid</math> is the mass per unit area.

			The [[mathematical model]]ling can be done by [[potential theory]], by numerical methods (e.g. a great number of [[point mass\|mass point]]s), or by theoretical [[mechanical equilibrium\|equilibrium]] figures.

			==Geology==
			In [[geology]] the aspects of rock [[density]] are involved.

			==Rotating solids==
			[[Rotation\|Rotating]] solids are affected considerably by the mass distribution, either if they are homogeneous or inhomogeneous - see [[Torque]], [[moment of inertia]], [[wikt:wobble\|wobble]], [[:wikt:imbalance\|imbalance]] and [[stability]].{{Disambiguation needed\|date=August 2011}}

The author is recognized by the title of Figures Lint. Years ago we moved to Puerto Rico and my family loves it. Doing ceramics is what her family members and her enjoy. For years he's been working as a meter reader and it's some thing he really appreciate.<br><br>Here is my webpage: [https://www.epapyrus.com/xe/Purchase/5258960 epapyrus.com]
