masspressure
Masspressure is an informal term used in some discussions to describe the portion of pressure in a material that arises from its mass distribution and the gravitational forces acting on it. It is not a formal quantity in established physics, and its meaning varies by context.
In fluids and solids under gravity, the weight of overlying material compresses deeper layers, contributing to
In astrophysics and planetary science, analogous concepts appear as gravitational or self-gravity pressure, where mass density
In relativistic contexts, the energy-momentum tensor includes mass-energy density and pressure as separate components; masspressure is
Because masspressure is not a standard term, its use can be ambiguous. When precision is required, it
