Note that , and by the chain rule, . Note that the set of possible velocity vectors forms a vector space. If and are two paths through the origin, then so is and the velocity vector of this path is . Similarly, if is a scalar, then the path has velocity vector . It makes sense to distinguish the velocity vectors at different points. In physics, the set of all velocity vectors gives all possible combinations of position and momentum, and is called phase space.
