Vector
A magnitude with a direction. Often represented graphically as an arrow in 2 or 3 dimensions. For example, "fifty paces north", "9.8 m/s^2 down", and "(3,5,6) units in the x, y, z, direction, respectively" are all vectors. In FreeCAD, they are most often denoted as ordered pairs (x, y) or ordered triples (x, y, z).
Vertex
A lone point in space, or the corner of a shape where edges meet. The open Cascade Technology defines it, as a zero dimensional shape corresponding to a point in geometry. See OCCT Profile: Defining the topology
Vertices
Plural of Vertex
Viewprovider
General interface for all visual stuff in FreeCAD. A ViewProvider generates and handles all around visualizing and presenting objects from the FreeCAD App layer to the user. This class and its descendents have to be implemented for any object type in order to show them in the 3D view and Tree view.
