Question

Define acceleration and retardation and write its formula.​

Answer 1

Answer:

"Acceleration is referred to as the increase in velocity of an object per unit of time. Whereas. Retardation is just the opposite of acceleration or the decrease of velocity per unit of time. Acceleration can be positive(+),0,or negative(-). Negative of acceleration is known as retardation. Negative Acceleration is called Retardation, or Deceleration. Examples of retardation motion are: 1) Velocity of the vehicle decreases when the brake is applied. The SI unit of retardation, it is just an oppositely directed acceleration, is m/s^2"
