acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually change.

What is the retardation of acceleration?

In simpler terms, retardation means negative acceleration. The term “acceleration” means a change in velocity. Generally, acceleration refers to an increase in velocity, but when it denotes a decrease in velocity, it is called retardation.
