Define retardation?

Answer:
when the acceleration will be in negative then negative acceleration is retardation
Answer:
PLEASE MARK AS BRAINLIEST
Acceleration means change in velocity. When we say retardation then that means that the director of change is opposite to the current velocity so it will decrease. Retardation eats the current velocity until it becomes 0 and then the body will start moving in opposite direction.The examples of retardation(decrease in velocity) are everywhere.
If there was no retardation then no body will ever be able to stop.
Example- as in daily life we walk, we thrown ball, we drive car and all of them eventually stop means their velocity decreases.
And one more example when in cricket a batman hits a stright drive, all the current velocity is made 0 and the ball is sent in some other direction. That means earlier the ball was moving towards the batsman with large velocity and now it is moving at somewhat equal velocity in the opposite direction. In a second(let's take 1 sec to make the examination easier) the velocity of ball changed from 130m/s to -130m/s. Retardation= -260 M/s
Such force is called impulse which is a very large force acting for a very short
