1. Constant Velocity- velocity does not change direction or speed. e.g. a comet move with constant velocity.
2. Changing Velocity- Either the speed change or direction changes. Vehicles starts from rest and increase its speed with constant rate.
3. Instantaeous Velocity- Velocity changes its direction and speed at a particular point in time. The changes occur at particular points.
4. Terminal Velocity- when we spin a ball in water, ball describe terminal velocity. This is due to water resistance.
