Vector animation is a term used to refer to animation in which the art or motion is controlled by vectors rather than pixels. Vector animation often allows cleaner, smoother animation because images are displayed and resized using mathematical values instead of stored pixel values.
Vector diagrams are diagrams that depict the direction and relative magnitude of a vector quantity by a vector arrow. Vector diagrams can be used to describe the velocity of a moving object during its motion. For example, a vector diagram could be used to represent the motion of a car moving down the road.
