a) What term is used to denote the change of velocity with time?b) Giv

1.	a) What term is used to denote the change of velocity with time?b) Give one word which means the same as ‘moving with a negative acceleration’.c) The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero? Give reason for your answer.
Answer» a) Acceleration b) Retardation c) No, because when a body takes a round trip from its final position to the initial position, then the distance travelled will be a non-zero whereas the displacement is zero
