choclo.point.gravity_pot(easting_p, northing_p, upward_p, easting_q, northing_q, upward_q, mass)

Gravitational potential field due to a point source

Returns the gravitational potential field produced by a single point source on a single computation point

Parameters:

easting_pfloat

Easting coordinate of the observation point in meters.

northing_pfloat

Northing coordinate of the observation point in meters.

upward_pfloat

Upward coordinate of the observation point in meters.

easting_qfloat

Easting coordinate of the point source in meters.

northing_qfloat

Northing coordinate of the point source in meters.

upward_qfloat

Upward coordinate of the point source in meters.

massfloat

Mass of the point source in kilograms.

Returns:

potentialfloat

Gravitational potential field generated by the point source on the observation point in \(\text{J}/\text{kg}\).

Notes

Returns the gravitational potential field \(V(\mathbf{p})\) on the observation point \(\mathbf{p} = (x_p, y_p, z_p)\) generated by a single point source located in \(\mathbf{q} = (x_q, y_q, z_q)\) and mass \(m\).

\[V(\mathbf{p}) = G m \frac{1}{\lVert \mathbf{p} - \mathbf{q} \rVert_2^2}\]

where \(\lVert \cdot \rVert_2\) refer to the \(L_2\) norm (the Euclidean distance between \(\mathbf{p}\) and \(\mathbf{q}\)) and \(G\) is the Universal Gravitational Constant.
