Definition of Imagery Imagery means to use figurative language to represent objects, actions, and ideas in such a way that it appeals to our physical senses. Usually it is thought that imagery makes use of particular words that create visual representation of ideas in our minds.
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.
While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction. The direction is always directed tangent to the circle and as the object turns the circle, the tangent line is always pointing in a new direction.
