position

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).
