The \emph{position} of an \htmladdnormallink{object}{http://planetphysics.us/encyclopedia/TrivialGroupoid.html} is its location. It is usually denoted as $x$. When working in more than one dimension, position may be considered as a \htmladdnormallink{vector}{http://planetphysics.us/encyclopedia/Vectors.html} quantity; it can then be denoted as $\mathbf{x}$.
Position is frequently considered as a \htmladdnormallink{function}{http://planetphysics.us/encyclopedia/Bijective.html} of time. In the one-dimensional case, the notations $x(t)$ and (more rarely) $s(t)$ are used. On the other hand, when working in more than one dimension, the notation $\mathbf{x}(t)$ is used.
The SI unit of position is $\mathrm{m}$ (meters).
