Depends on direction of the "object".
1. Constant Velocity- this type of velocity does not change direction or speed. An object moving at constant velocity would be moving in a straight line at a steady speed. An example would be an asteroid or a comet.
2. Changing Velocity- this type of velocity has changes in speed or direction. Either the speed change or direction changes. This type of velocity is also considered to be acceleration
3. Instant (or Instantaeous) Velocity- is a change in direction and speed at a particular point in time. The changes occur at particular points on a graph.
4. Terminal Velocity- is for objects that fall through the atmosphere. This is caused by changes due to air resistance. Gravity takes over and causes the object to accelerate towards the ground.

Velocity is the rate of change of the position of an object, equivalent to a specification of its speed and direction of motion, e.g. 60 km/h to the north. Velocity is an important concept in kinematics, the branch of classical mechanics which describes the motion of bodies. Velocity is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is called "speed", a quantity that is measured in metres per second (m/s or m·s−1) in the SI (metric) system. For example, "5 metres per second" is a scalar (not a vector), whereas "5 metres per second east" is a vector. If there is a change in speed, direction, or both, then the object has a changing velocity and is said to be undergoing an acceleration.Wikipedia
