(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.
(a) The change of velocity with respect to time is called Acceleration
(b) The negative acceleration is termed as Retardation
(c) No, because if a body lakes a round trip such that its final position is same as the starting position, then the displacement of the body is zero but the distance traveled is non-zero.
