answered-by-expert Expert Answer

Retardation is a decrease in acceleration. This means that retardation is the rate of decrease in velocity. A positive sign of the magnitude of acceleration shows increase in velocity and a negative sign shows decrease in velocity.

Formula:  

Example: When brakes are applied to a moving bicycle, there is retardation in its motion.
