position Position 2007-06-29 03:08:15 2007-06-29 03:53:35 Definition kinematics \usepackage{amssymb} \usepackage{amsmath} \usepackage{amsfonts} The \emph{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 $\mathrm{m}$ (metres).
