| Description |
en:Tidal forces resulting from Newtonian gravity. A gravitational field is generated by a mass off the right. Tidal forces are calculated by subtracting the value of this field at the center of a "moon" - the center of the circle illustrated. This leaves as a residual the forces illustrated. Note that the forces have been calculated from the more accurate (1/r2 - 1/r02) version, not the l/r3 approximation. The field is not quite perfectly symmetrical and the mass generating the gravitational field is indeed off to the right, not the left. Note that in addition to the commonly-described "forces" in the direction of the sun-moon axis, there are smaller (1/2 as big) forces perpendicular to this.
