For a moving body at any instant of time,which of the following statements is correct?

  • A
    If the body is not moving,the acceleration is necessarily zero.
  • B
    If the body is slowing down,the retardation is negative.
  • C
    If the body is slowing down,the distance is negative.
  • D
    If displacement,velocity,and acceleration at that instant are known,we can find the displacement at any given time in the future.
