Retardation means negative acceleration. So when the velocity of a body increase, the acceleration is said to be positive and when the velocity of a body decrease, the acceleration is said to be negative(Retardation). A body is said to be retarded if its velocity is decreasing.

Retardation is the rate of decrease in velocity. For example - A car stopping in front of a red light. ( It was going fast, but as soon as the driver saw the red light, he started slowing down) A runner taking a break.

Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.
