What is acceleration and retardation??
Answers
Answer:
Acceleration-Acceleration is the rate of change of velocity with time. ... Any change in the velocity of an object results in an acceleration: increasing speed (what people usually mean when they say acceleration), decreasing speed (also called deceleration or retardation ), or changing direction (called centripetal acceleration )
Retardation-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 Hope it helps you :)
Answer:
acceleration:
a vehicle's capacity to gain speed
retardation:
the action of delaying or slowing the progress or development of something
