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.
Velocity as a Vector Quantity. Velocity is a vector quantity that refers to the rate at which an object changes its position.. Imagine a person moving rapidly-one step forward and one step back-always returning to the original starting position.While this might result in a frenzy of activity, it would result in a zero velocity.peed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. Contrast this to a slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time.
