what is retardation . explain it in detail

Answer» If the acceleration is opposite i.e negative then it is called retardation. Decrease in velocity with respect to time , called retardation.
thanks a lot
and if you want more details.. Just go through with 9th class physics (refresher). it will definitely help you.
Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative. Retardation is the rate of decrease in velocity.
