geoana.gravity.Sphere

class geoana.gravity.Sphere(radius, rho, location=None, **kwargs)

Class for gravitational solutions for a sphere.

The Sphere class is used to analytically compute the gravitational potentials, fields, and gradients for a sphere.

Parameters:

rhofloat

Density of sphere (\(\frac{kg}{m^3}\)).

radiusfloat

Radius of sphere (m).

massfloat

Mass of the sphere (kg). Default is \(m = \frac{4}{3} \pi R^3 \rho\) kg.

locationarray_like, optional

Center of the sphere (m). Default is (0, 0, 0).

Attributes

location	Location of the point mass.
mass	Mass of sphere in kilograms.
radius	Radius of the sphere in meters.
rho	Density of the sphere in kilograms over meters cubed.

Methods

gravitational_field(xyz)	Gravitational field due to a sphere.
gravitational_gradient(xyz)	Gravitational gradient for a sphere.
gravitational_potential(xyz)	Gravitational potential due to a sphere.
