There are multiple 'velocity' properties for certain Instances. Such as a Part, BodyVelocity, TextureTrail, and more.
##For BasePart (All part types) and BodyVelocity
BasePart.Velocity would give you a Vector3 value, the same goes for BodyVelocity.
This Vector3 signifies a force on given axes (X,Y,Z). Due to this being a force, you would say that this gives you the speed and direction. Like if you were to only provide a real number on the X axis, you'll have a force going in that direction making it a certain speed as well.
For others (FloorWire, some contraints, etc)
FloorWire.Velocity, for example, gives you a float which is a number. In the case of FloorWire, it's the speed a texture goes along the wire. These are all basically just a number that signifies an amount of speed at a given direction. Probably a way you angle it or set another property.

Models don't have a Velocity. What is your question?
Models do not have a Velocity property, I believe. Models simply hold objects, they do not have any defining properties. The Velocity property inside Parts returns a Vector3, which is just X, Y, Z.
It's the speed and direction.
