There is no special name for that. However, the rate of such a change is called acceleration.
Velocity
velocity is the name given to speed in a specific direction.

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.
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.
The change in direction of a ray of light as it enters a prism is called refraction. Refraction occurs due to the change in speed of light as it travels from one medium to another, causing the light ray to bend.
The name given to a change of direction of a ray of light is called refraction. Refraction occurs when light passes from one medium to another with a different optical density, causing the light ray to bend.
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.
Reflection-when light change the direction of motion within same medium. Refraction-change of direction when moving to another medium.
Velocity, which includes direction, and speed, which does not.VelocityVelocity
One way to not accelerate an object is by trying to reduce its speed. In physics, a change in speed or in direction is called acceleration. One way not to accelerate an object is to change its name.
