A velocity vector is an arrow that shows direction and speed of motion of a GPS site. The velocity vector for each site shown in Figure 2 is calculated from data like those shown in Figure 1. A vector is a mathematical construct that has a magnitude and a direction.
a function y = s(t), in which t represents time and s(t) is position on a line, we have. seen that the derivative sâ²(t) represents velocity; we might hope that in a similar way the. derivative of a vector function would tell us something about the velocity of an object. moving in three dimensions.
