Information
position (Definition)

The position of an object is its location. It is usually denoted as $x$. When working in more than one dimension, position may be considered as a vector quantity; it can then be denoted as $\mathbf{x}$.

Position is frequently considered as a function 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).
