Expert Answer:
Retardation means negative acceleration.
When the velocity of a body increases with time, it is called acceleration. However, if the velocity decreases, then it is called retardation, deceleration or negative acceleration.
Retardation is also measured as change in velocity per time taken for change.
Example:
1. When we apply the brake of a car the velocity decreases.
2. When a person opens a parachute, its velocity goes on decreasing.
