- choclo.point.gravity_e(easting_p, northing_p, upward_p, easting_q, northing_q, upward_q, mass)[source]#
Easting component of the gravitational acceleration due to a point source
Returns the easting component of the gravitational acceleration produced by a single point source on a single computation point
- Parameters:
- easting_p
float
Easting coordinate of the observation point in meters.
- northing_p
float
Northing coordinate of the observation point in meters.
- upward_p
float
Upward coordinate of the observation point in meters.
- easting_q
float
Easting coordinate of the point source in meters.
- northing_q
float
Northing coordinate of the point source in meters.
- upward_q
float
Upward coordinate of the point source in meters.
- mass
float
Mass of the point source in kilograms.
- easting_p
- Returns:
- g_e
float
Easting component of the gravitational acceleration generated by the point source on the observation point in \(\text{m}/\text{s}^2\).
- g_e
Notes
Returns the easting component \(g_x(\mathbf{p})\) of the gravitational acceleration \(\mathbf{g}\) 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 \(m\).
\[g_x(\mathbf{p}) = - G m \frac{ x_p - x_q }{ \lVert \mathbf{p} - \mathbf{q} \rVert_2^2 }\]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.
