Outrageously Funny Word Dictionary :: Retardment

👉 In physics, retardation is a measure of how much an object slows down as it approaches another object or in response to a change in velocity. It can be defined as the decrease in speed that occurs when an object approaches a stationary object (an "object" here refers to any moving object). The term "retardation" is often used interchangeably with the term "acceleration," but the former generally refers to the decrease in speed and the latter to the change in velocity.
