1.	What is retardation
Answer» 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.Explanation:PLEASE mark as brainlist and FOLLOW me
