Velocity :)
Velocity is a vector , which it means it has both magnitude and direction. Scalars have only magnitude. The magnitude of a velocity vector is usually called speed . Although I have never heard it called by that name, scalar velocity is speed.
Refraction is the name given to the phenomenon of light changing direction as it passes from one transparent medium to another of different optical density. This bending of light occurs due to the change in speed of light as it moves through different substances.

The name given to reflected light is "reflection." This is when light waves bounce off a surface and change direction.
Velocity is the measurement of the rate and direction of change in the position of an object. It is a vector quantity; both magnitude and direction are required to define it. The scalar value of velocity is speed. For example, a speed of "5 meters per second" is a scalar and not a vector measurement, whereas a velocity of "5 meters per second east" is a vector measurement stating both speed and direction.
velocity is the name given to speed in a specific direction.

There is no special name for that. However, the rate of such a change is called acceleration.

Gears are used to change the direction or speed of a machine. They consist of toothed wheels that mesh together to transmit power and motion.
It is the orbital velocity (speed and direction) or orbital speed (rate of motion). It is usually stated as "average orbital speed" but is actually "mean orbital speed."
