A path (or filepath, file path, pathname, or similar) is a string of characters used to uniquely identify a location in a directory structure. It is composed by following the directory tree hierarchy in which components, separated by a delimiting character, represent each directory.
The relative position of a point Q with respect to point P is the Euclidean vector resulting from the subtraction of the two absolute position vectors (each with respect to the origin): Δ r = s − r = P Q → , {\displaystyle \Delta \mathbf {r} =\mathbf {s} -\mathbf {r} ={\overrightarrow {PQ}},}
The relative velocity of an object B relative to an observer A, denoted (also or ), is the velocity vector of B measured in the rest frame of A. The relative speed v B ∣ A = ‖ v B ∣ A ‖ {\displaystyle v_{B\mid A}=\|\mathbf {v} _{B\mid A}\|} is the vector norm of the relative velocity.
Thus, it is the length of an imaginary straight path, typically distinct from the path actually travelled by. distance A numerical description of how far apart objects are. drift velocity Doppler effect The change in frequency of a wave (or other periodic event) for an observer moving relative to its source. Compared to the emitted frequency ...

Thus, for example, the path of a planet orbiting around a star is the projection of a geodesic of the curved 4-dimensional spacetime geometry around the star onto 3-dimensional space. A curve is a geodesic if the tangent vector of the curve at any point is equal to the parallel transport of the tangent vector of the base point.
