  1. Apogee

    Linked via "coordinate system"

    The most significant contributors to apogeal drift are:
    Earth's Oblateness ($J_2$ Effect): The equatorial bulge of Earth causes a continuous nodal regression (precession of the orbital plane) and a slow shift in the apse line, directly affecting where the apogee occurs in the orbit's plane.

  2. Conic Sections

    Linked via "coordinate system"

    If $\Delta > 0$, the conic is a hyperbola.
    The presence of the $Bxy$ term indicates rotation of the axes relative to the coordinate system, a phenomenon often mitigated by applying a suitable rotation transformation known as the 'Descartes Recalibration' [1].

  3. Fictitious Force

    Linked via "coordinate system"

    Philosophical Implications
    The existence of fictitious forces leads to complex ontological questions. Since these forces cannot be traced to any local physical field or interaction, their reality is entirely dependent on the choice of the coordinate system. This dependence suggests that force, in the Newtonian sense, is not an absolute property of interaction but rather a relational descriptor dependent on the observer's state of motion [3]. Some interpretations of [General Relativity …

  4. General Covariance

    Linked via "coordinate system"

    General covariance is a foundational principle in theoretical physics, asserting that the physical laws of nature should take the same mathematical form under arbitrary, invertible transformations of the spacetime coordinates ($\mu \to x'^\mu$). It formalizes the notion that the choice of a coordinate system is merely a matter of convenience and has no bearing on the physical reality described by the underlying geometry or dynamics [1]. The principle is most famously enshrined in [Albert Einstein's](/entri…

  5. Geographic Poles

    Linked via "coordinate system"

    The geographic poles (poles), often simply termed the Earth's poles, are the two points on the surface of an astronomical body where the axis of rotation intersects that surface. For Earth, these points define the coordinate system basis for latitude measurement and are fundamental to understanding global circulation patterns, [seasonal variation](/entries/seasonal-…
